[flexcoders] charting and/or grid replacements

[Pan Troglodytes]

Are there any 3rd-party charting and/or grid replacements in progress that
anyone wants to talk about?  I'm looking to move away from the
AdvancedDataGrid and possibly also Flex charting and am wondering what might
be on the horizon.  Right now Adobe pretty much has the only game in town
for these Flex components as far as I know.

I really wish DevExpress could be brought around to developing for Flex.
Their grid components can have a incredibly steep learning curve due to the
staggering amount of features, but I've found them to be quite a perfect fit
with a professional quality application.  I can only imagine what they'd
build from scratch for Flex.

This is not to dump on Adobe, necessarily.  They're trying to organize their
budget where they thing it's most effective, even if I disagree with it.
But without a rich 3rd-party component ecosystem, I'm afraid that this great
technology (I'm totally in love with the general process of programming for
Flex) might wither on the vine.

Re: [flexcoders] custom components destroy Flex design mode ....

[Pan Troglodytes]

I've run into similar situations before with 3rd party components.  For some
reason, some of them just utterly break the MXML design mode.  I've also
done it myself when subclassing the charting components.  You just get a big
rectangle with a big red X over the whole area.

Re: [flexcoders] Re: why does my MXML act differently than my AS?

[Pan Troglodytes]

Yes, that's what I was referring to in the first post about digging through
the generated source.

I'm torn on whether to submit this as a "bug."  I wish someone at adobe
could step in and say "well, that's not equivalent MXML because you forgot

Re: [flexcoders] Re: how can you make the icon in an AdvancedDataGridGroupItemRenderer accept clicks?

[Pan Troglodytes]

Yes, I wondered why they set it, too.  It's quite mysterious.

And as far as extending ADGGIR - have you looked at that code?  They were
good about making very little of it private or mx_internal (yes, I know I
can get around the latter), but the bulk of it is done in commitProperties.
So you'd be limited to just stuff you could take on to the end of the
overridden function.  Likely I'd just clone the unit and change the bit of
code I was interested in.

Re: [flexcoders] Re: how can you make the icon in an AdvancedDataGridGroupItemRenderer accept clicks?

[Pan Troglodytes]

Well, the main reason I wouldn't want to write my own itemRenderer is that
AdvancedDataGridGroupItemRenderer does a lot of stuff I wouldn't want to
have to reinvent.  It also interacts with stuff like iconFunction that would
be annoying to re-implement.  Plus, there's the fact that there's a high
likelihood that what I wrote would be much less efficient.

But good news!  I found a simple way to achieve what I want:


http://www.adobe.com/2006/mxml";
  >
  
<![CDATA[
  // put any icon you want in the embed below, doesn't matter
  [Bindable] [Embed(source="imageA.png")] private var imgClass:Class;

  private function geticon(item:Object):Class
  {
return imgClass;
  }
]]>
  
  

  

  


  


  
 
  


The key was setting mouseEnabled=true.  It is set to false in the
constructor for ADGGIR.  I'm not sure why, and I am a little worried that I
may be messing up something important.  So far I haven't noticed any odd
behavior.  But if anyone knows a good reason WHY mouseEnabled is set this
way, please followup.

No ideas on how to do this at all?

[flexcoders] why does my MXML act differently than my AS?

[Pan Troglodytes]

I have a test program that, as far as I can tell, does the same thing using
an MXML component and the equivalent actionscript.  When I click on the
button to execute the AS version, everything is fine.  But when I click on
the button to execute the MXML version, I get a layout flicker.  It's bad
enough that if you try to click on the MXML button over and over really
fast, you'll wind up clicking the main app and the menu will go away.
Here's the code:



http://www.adobe.com/2006/mxml";
  layout="absolute"
  >
  

  

  

  

  

  


  

  

  

  


TestGridRow.mxml:

http://www.adobe.com/2006/mxml";>
  

  



I've dug through the generated code and have not been able to find anything
that I think would account for the problem.  This is frustrating, because
what I really want to do is a more complicated MXML component to make it a
lot nicer to add rows in my addCategory function.  But I can't as long as
it's going to be so jittery.

Thanks!

Re: [flexcoders] Re: how can I get a popupButton's popUp to resize while popped up?

[Pan Troglodytes]

Yet another correction:
grid.scrollRect = new Rectangle(0, 0, Math.max(grid.width,
gr.measuredWidth),
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));

Didn't make sense to add the width in this example.

I thought you were referring to the last couple of threads of mine you've
posted on.  :D

But yes, I do remember that old post.  Can't believe it was "years ago"!
Where does the time go?

Oh, that's right, the bugs in my program eat most of it!

Re: [flexcoders] Re: how can I get a popupButton's popUp to resize while popped up?

[Pan Troglodytes]

I should know better by now to never declare victory until you tried your
test app solution in your REAL app.

A problem occured that if your popupbutton is embedded in another control,
the "y" value will no longer be in the same frame of reference as the popup,
which is no a child of the same control as the popupbutton.  So this may not
be the BEST way to do it, but it works:

gr.validateSize(true);
var verticalGap:Number = grid.getStyle("verticalGap");
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));
if (grid.localToGlobal(new Point(0, 0)).y < grid.owner.localToGlobal(new
Point(0, 0)).y)
  grid.y -= gr.measuredHeight + (isNaN(verticalGap) ? 0 : verticalGap);

Re: [flexcoders] Re: how can I get a popupButton's popUp to resize while popped up?

[Pan Troglodytes]

C'mon, Tim, your posts help me loads of times and you don't even realize
it.  My #1 place to go for searching for answers to tough problems is my
flexcoders archive and your name pops up a lot with the answer!  And
RowColorDataGrid was a lifesaver.


Okay, back to the topic.  Just realized that there's a little something
missing.  If you have the popupButton on the bottom of the window so that it
causes the popup to appear ABOVE it, then the code above glitches in that it
makes the window grow down and cover the popupbutton.  Here's a fix:

gr.validateSize(true);
var verticalGap:Number = grid.getStyle("verticalGap");
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));
if (grid.y < myPopupButton.y)
  grid.y -= gr.measuredHeight + (isNaN(verticalGap) ? 0 : verticalGap);

To see this in action in the above example, set the application
layout="absolute" and the myPopupButton bottom="0".

Of course, when you add so many categories that it gets taller than the
window its in, then you're screwed!  You'd have to implement your own "don't
grow when bigger than this and turn on scrollbars instead" logic.  Luckily I
don't need that right now.

Re: [flexcoders] Re: how can I get a popupButton's popUp to resize while popped up?

[Pan Troglodytes]

Thanks, Tim.  Knew there must be something, just couldn't find it.

I found this to be a good way to do it, as long as I'm not missing
something:

gr.validateSize(true);
var verticalGap:Number = grid.getStyle("verticalGap");
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));

This seems more "right", though if you add some big numbers to height and
width it will always auto-calc them.  But I found if you add numbers that
are too small, you wind up with it chopped off a bit.

[flexcoders] how can I get a popupButton's popUp to resize while popped up?

[Pan Troglodytes]

Okay, so given the following application:


http://www.adobe.com/2006/mxml";
  >
  

  
  

  

  

  


  

  
  

  


  

  
  

  


  

  

  

  


I want to be able to click the popupButton, click the "Add Category" button,
and have the popped up window resize right then so you can see everything.
Is there a good way (or even an ok way) to do this?

[flexcoders] getting files in additional Source Paths to automatically recompile

[Pan Troglodytes]

I have a couple of external folders listed in my project's Flex Build
Path->Source Path section.  These folders are outside of my project
hierarchy and contain some common  files I share between several different
projects.

When I'm in my project and ctrl-click on an object in these files, it opens
the file properly.  But if I make changes and hit save, it doesn't recompile
my project to include those changes.  If I make changes in the project and
it rebuilds, it still doesn't get the changes in that external file.  Only
when I do a Project->Clean does it recompile those external files in.

Is there some better way of setting it up so that it will be more
intelligent about figuring out it needs to recompile those files on changes?

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

I think you missed the part above where I said more than one item could be
activated.  Some items can be locked on, and it also includes the currently
selectedItem (which can be different than the one being moused over).  The
examples were dumbed down so people could easily figure out where I was
seeing the problem.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

Yes, a mushroom indeed - well put!  By the way, I found your posts about
your fun with the various ADG item renderers quite informative.  Though you
did leave me wishing for some source code of the working examples.

The problem here is that this data serves to link up different parts of the
UI.  It's so that many different pieces can look in one place and hook to
one set of variables.  It also serves as abstraction.  I have a chart that I
can instantiate any number of copies of (with different views of the data,
etc.)  I don't want this chart to have to have knowledge of this one fixed
grid.  The grid is also reused in a couple of different ways, so i don't
want the grid to be hardcoded to the chart.

It's the perils of abstraction and modularization.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

This seems like probably the best option.  I suspected that it was something
to do with properties changing causing excessive refresh, but the fact that
Alex didn't point that out as the problem kind of threw me off track.

It appears that the highlight is set in drawItem, so I subclassed ADG and
overrode it, setting the highlight property.  I added a bit to the highlight
to make sure the event only gets fired if the value actually changes.

As to your question of using selectedItem, the problem is twofold.  First,
the problem is that the grid doesn't provide any property for
highlightedItem.  Yes, as Tim said I could subclass and create one (much
like I did above).  But the secondary problem is that I want several bits of
code that aren't interconnected to do something when a given item in the
data list is "active."  I don't want these different bits of the code to
have to know about controls and grids.  I just want them to see a data
element changing and respond to it.  Secondly, this is complicated by the
fact that I can "lock" some elements into the active state.  So I might have
item 2, 4 and 8 locked on and be mousing over item 5.  The other component
will show items 2, 4, 5 and 8 all active.

By the way, Tim, I had composed this as a response to your suggestions but
not go around to sending it to you yet:
Well, the problem with that and with your example is that they rely on the
itemRenderers to do the management of the highlighted variable.  That was a
tangent I got on to show that it wasn't just the fact that it runs through
an ArrayCollection that was breaking it.  The problem with the itemRenderers
managing it is that there is "dead space" between item renderers (i.e.
padding) that the renderers never see.

Thanks everyone for your input on the problem!

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

1) Yes, this works fine, for the display portion only.  It doesn't address
the actual problem of needing to set a flag in the data that indicates it is
the currently highlighted one, that flag being also used by other things
that bind to the data that don't want to know about UI details like the
grid.  In this case, I had a number of chart listeners that would toggle
series on/off depending on which one was highlighted in the grid.

2) There is no commitProperties on AdvancedDataGridItemRenderer.  Perhaps
you meant validateProperties.  In this example, it gets called only when the
grid is first displayed and not when any item is highlighted/de-highlighted
or selected/de-selected.

3) Yes, the styleFunction does get called when the highlighted object
changes.  But if you move the code to set data.highlighted there, you get
the same result!  It just seems like anything that changes this bound
variable on every repaint of the cell is doomed to break the rollover
highlight.

[flexcoders] how can you make the icon in an AdvancedDataGridGroupItemRenderer accept clicks?

[Pan Troglodytes]

I've got a bit of a problem and haven't been able to figure it out.  When
using hierarchical views with ADG, I find that the icon can't be clicked on
to select the row.  I can't figure out how to capture a click on the icon at
all.

If you click anywhere but the icon, the gridclick and itemclick events both
fire.  But if you click on the icon, you get only the gridclick.  And the
gridclick event doesn't get anything useful for target/currentTarget, as far
as I can tell.

The main thing I really want to do is have clicking on the icon select the
row, just like clicking anywhere else will do.  Tangentially, it would be
nice to know how to capture the event in case I wanted to do something
different with clicking on the icon.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

Oh yeah, another thing I should point out is that in the real grid, I have
multiple columns.  As such, a solution that relies on the itemRenderer might
be problematic due to gaps between items and such.  I would just use the
itemRollOver and itemRollOut to do it all, but rollOut doesn't get reliably
called for every highlighted row when the highlight leaves it.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

That was a good idea and it does get rid of the arraycollection walking.
But I get the SAME problem with the grid losing highlighting when I did it
using AdvancedGridItemRenderer, thought the symptoms are slightly different:

  private function cc():void
  {
for (var i:int = 0; i < ITEM_COUNT; i++)
{
  var item:TestObject = new TestObject;
  item.label = "Item " + i;
  d.addItem(item);
}
  }

  }
]]>
  

  

  

  



In this example, I don't loop through the dataprovider but instead only
affect the itemRenderer being redrawn.  Yet if you try this example with
highlighted being a [Bindable] variable, it breaks, not just failing to show
the highlighted item in bold but also breaking the grid's blue highlight.
Comment out the [Bindable] part in TestObject, and it works just fine.

I'm hoping Alex is still following along.

I'm trying to get my itemRenderers in a big complicated grid as lean as
possible, as per Alex's suggestions on his blog.  The highlighted data is
also being used in a couple of different places that are abstracted a bit,
otherwise I'd hardcode something a bit more kludgy.

Re: [flexcoders] how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

Yes.  A gigantic 15 items.  ;)  I wouldn't have thought going through a list
of 15 items would be quite so processor intensive.

Though even if it's just 5 items and I use Array instead of ArrayCollection,
it's still choppy.

The problem isn't so much that it's scanning through the entire collection,
as if you change "item.highlighted = list.isItemHighlighted(item)" to "
trace('here');", the choppiness disappears.

So, the problem is that it's setting this bound variable highlighted 15
times (or even just 5) for each item as it rolls over them.  And the strange
thing is that the data all gets set behind the scenes.  What happens that
the grid cells don't get repainted properly.  If you actually play with the
program a little, dragging your mouse around a bit, you'll see what I'm
talking about.  Here's a video that might be helpful:

http://www.youtube.com/watch?v=7LQFlQtiHsc

So it seems odd to me that the data is getting updated but the grid is
losing track of the ability to highlight.

You know what's really interesting?  Change the style function this:
private function getColStyle(data:Object,
column:AdvancedDataGridColumn):Object
{
  return { fontWeight:(data.highlighted ? "bold" : "normal") }
}

Now you'll see that the bolding tracks perfectly!  The reason it failed
before was the same reason the blue mouseover highlight was failing.
Internally, the grid is losing the ability to highlight.

[flexcoders] how to fix poor performance in this example (AdvancedDataGrid and Binding)

[Pan Troglodytes]

I have the following example that is a very simplified form of what I need
to do in my much larger program.  The goal is to have a mouseover on a grid
item set a variable in the data object.  In the real program, this fires off
some other code which makes that item visible and the others hidden, etc.
But here, I'm just trying the first part.

*TestObject.as:*
package
{
  public class TestObject
  {
[Bindable] public var label:String;
[Bindable] public var highlighted:Boolean;
  }
}

*GenericTest.mxml:
*
http://www.adobe.com/2006/mxml";
  creationComplete="cc()"
  layout="horizontal"
  >
  

  
  

  

  
  

  

  


To see the problem, run your mouse up and down the list on the left and the
list on the right.  If you get the same results I do with SDK 3.0.2 and
player 10,0,12,36 (FF 3.0.6 or IE 7), you'll see that the list on the right
tracks very smoothly but the one on the left is choppy.  The only difference
between the two is that the one on the left has a rollOver handler that sets
a Bindable variable in the data object.

If you comment out the [Bindable] on TestObject's highlighted variable, the
choppiness goes away.  So it's something to do with all the binding glue
being fired behind the scenes.  Is there some good way to work around this
while still being able to use binding in this way?

Re: [flexcoders] Re: using "as" breaks data binding?

[Pan Troglodytes]

I'm not sure I fully understand what you mean, Alex.  In my button click
code, I modify the properties.  Could you clarify that?  Do you also mind
jotting in a comment on the but reports I entered to just confirm that you
were able to reproduce it in 4.0?

Does this mean "as" should be avoided and only used in cases where the
ClassName() syntax will wind up doing more than just type coercion (like
Array) for now?

Thanks.

Re: [flexcoders] Re: using "as" breaks data binding?

[Pan Troglodytes]

Well, I entered the two related issues as:

https://bugs.adobe.com/jira/browse/SDK-21100
https://bugs.adobe.com/jira/browse/SDK-21101

Maybe someone at Adobe can manage to reproduce them.  I'm not really sure
how much harm is being done, since the code appears to work right in the
end.  But someone weird and unexpected seems to be going on under the hood.

Re: [flexcoders] Re: using "as" breaks data binding?

[Pan Troglodytes]

Thanks for giving me some confirmation.  Now if we could just figure out
what Alex/Adobe need to do to replicate our tests.

The reason it doesn't give a warning on "y" is due to what I referenced
(perhaps unclearly) above.  Notice in the warning it tells you it can't bind
to that value on the *itemRenderer *(GenericTest_inlineComponent1 in my
test), not on the *TestObject* instance.  The itemRenderer has an x and y
object, so that's why it doesn't complain.  It doesn't make any sense that
it should be looking at binding to the itemRenderer instead of the
TestObject instance, though.

Re: [flexcoders] using "as" breaks data binding?

[Pan Troglodytes]

I wonder if I wasn't clear enough on this - these are run-time warnings that
output to the console.  You don't get those?

Re: [flexcoders] using "as" breaks data binding?

[Pan Troglodytes]

3.3.0.  I also get it with 4.0.0.6137.  Just downloaded and got it in 6772,
too.  I'm using player version 10,0,12,36.  Do you need to know anything
about my Flex Builder version?  Let me know anything else I can provide.

When you say you don't get it with the soon-to-be 3.4, what exactly do you
mean?  You just don't get the run-time warning?  Did you track down why it
would be okay with "x" and see if that's still doing whatever weird thing it
is in 3.4?

[flexcoders] using "as" breaks data binding?

[Pan Troglodytes]

I've run across some peculiar behavior and I am trying to figure out if I
should report it and if so, how exactly to explain it.  Given these two bits
of code:

*TestObject.as:*
package
{
  public class TestObject
  {
[Bindable] public var a:uint = 2;
[Bindable] public var b:uint = 3;
[Bindable] public var x:uint = 1;
  }
}

*Main Application:*

http://www.adobe.com/2006/mxml";
  >
  

  
  

  

  
  
  

  

  
  


If you run this application, you get the following warnings:
warning: unable to bind to property 'b' on class
'GenericTest_inlineComponent1'
warning: unable to bind to property 'b' on class
'GenericTest_inlineComponent1'
warning: unable to bind to property 'b' on class
'GenericTest_inlineComponent1'
warning: unable to bind to property 'b' on class
'GenericTest_inlineComponent1'
warning: unable to bind to property 'b' on class
'GenericTest_inlineComponent1'
warning: unable to bind to property 'b' on class
'GenericTest_inlineComponent1'

There's a couple of things that stand out here.  First, it doesn't complain
about properties "x" or "a".  The reason it doesn't complain about property
"a" is that I used "TestObject(data).a" instead of "(data as
TestObject).a".  If you change it to the other way around, you will get a
warning on "a" as well.  I find this rather bizarre, as I thought there was
no functional difference to the two, other than "as" returning null if the
object wasn't of the appropriate type rather than just erroring out like
straight type coercion does.  But type coercion/as are very (ahem) "lightly"
documented so I admit I don't know a lot.  But I don't think it's because of
the null problem, since you can replace it with "TestObject(null).b" and it
stops giving the warning.

The second weird thing is that it doesn't complain about "x" when using
"(data as TestObject).x" like it does with a.  As you can see, it's claiming
this error is on GenericTest_inlineComponent1.  This is significant because
it appears that it's instead doing some binding to the "x" property on the
item renderer, which is *very* odd.  You can try this yourself by changing
"x" to other strings.  Ones where there is a property of HBox named the same
thing won't give you a warning.  Others will.

Yet for all this griping, it seems the data binding IS working.  If you
click on the button, you'll see all the labels in the list change as the
data is being changed.

So, anyone want to shed some light on these two behaviors?

Re: [flexcoders] where does AdvancedDataGridColumn.id come from?

[Pan Troglodytes]

Well, there is an there isn't.  UIComponent actually defines a property of
called "id."  AdvancedDataGridColumn isn't a UIComponent, its a descendant
of CSSStyleDeclaration, which does not define "id", nor does its ancestors.
So I guess I really knew the answer before I asked it in that it's a bit of
a kludge to let you name objects in MXML so you can refer to them later.
Then at runtime, this information just isn't there because it really never
existed.

[flexcoders] where does AdvancedDataGridColumn.id come from?

[Pan Troglodytes]

This puzzles me a bit.  There is no such property as "id" on
AdvancedDataGridColumn or its ancestors.  So why doesn't the compiler barf
and give you an unknown property at compile time (it does at runtime)?  Is
this some kind of kludge in FB such that it always allows an element called
"id" to be stuck on some components (like CSSStyleDeclaration descendants)?

Re: [flexcoders] for better performance, use "as" rather than just leaving an object as Object?

[Pan Troglodytes]

Thanks for the input, Alex.  True, it did take a lot of iterations to get a
one second difference, but that's with only one reference to a property.  If
I had something like:   o.foo.bar[3].baz = o.foo.getBaz(), I've suddenly
quintupled the number of FindProperty calls.  Ditto if I had a few lines of
calls, all working off of o.

But mainly I agree that you have to consider whether a given "optimization"
is worth it if the code doesn't actually need optimizing and the
optimization will make the code harder to understand and maintain.  That's
why this is such a good tip, since I wanted to use "as" anyway to make the
code more maintainable!  Good point about SWF/RAM size, though.

You finally got me to bother setting up some RSS subscriptions in
thunderbird.  I always mean to read the various excellent Flex blogs, but
never get around to it.  Maybe this way I'll be more likely to get those
useful nuggets of knowledge.  I'm already looking forward to implementing
some of your tips on itemRenderers (especially the image centering ones) to
try to speed up a particularly painful ADG redraw.

[flexcoders] for better performance, use "as" rather than just leaving an object as Object?

[Pan Troglodytes]

I was curious as to the difference between a few different ways of
approaching the situation of an itemRenderer having a "data" property and
deciding whether or not to use "as" to make all the type checking happy.  So
I tried some test code and found that it made a big difference whether you
use "as" or just leave the data property as an Object.  If you leave it as
an Object, you get a performance hit on the order of 40%+ longer than if you
use "as" to cast it first.

Here are the ways I tested it.  I just decided to pull the "id" property
because it's something that is just a simple access of a private variable,
no complicated stuff.

var b:Button = new Button;
var o:Object = b;
var s:String;

s = b.id;
s = (o as Button).id;
s = Button(o).id;
s = UIComponent(o).id;
s = (o as UIComponent).id;
s = o.id;

I did get a bit fancy and put them in a loop and a timer to isolate each
one.  The full code is included below.

What I found was along the lines of this (give or take a few %):

Button: 3.16
Button():   4.06  129%
as Button:  4.14  131%
UIComponent():  3.98  126%
as UIComponent: 4.03  128%
Object: 5.38  170%

I put in the UIComponent ones because sometimes I cast it to a superclass
because I might get several different subclasses passed into a function.

So what I've found is that if you ignore than noise, the middle four methods
are also approximately the same in timings.  But the Object one is far
worse.  This probably won't come as any surprise to the Adobe folks or the
people who have been working with Flex a bit more in-depth.  I found it
rather useful information, though, considering I'm trying to shave off some
time in various places in one of my apps.  Granted, it won't matter as much
outside of loops.

So many things return the items as objects, such as Arrays/ArrayCollection,
the "data" property of item renderers, etc.  I think I'm just going to make
it a habit to put "as" in my code (and not the format of Class(variable)
because sometimes that triggers a function rather than just doing a casting)
all the time.  It helps catch errors by doing strict type checking (as long
as you aren't using dynamic classes) and it's a little faster to boot.

Still, I wish it was as fast as the top line where you don't have to do any
casting/as at all.  Any thoughts on that or anything else I've missed?  Any
flash insiders want to give your insight on why it works this way under the
hood?

Re: [flexcoders] ADG Code Completion Missing

Well, either I got confused before and though it was working when it was
still broken, or it's more complicated.

It's back to not working at all for me under 3.3.0 for any Advanced* classes
n MXML or ActionScript.

Re: [flexcoders] ADG Code Completion Missing

[Pan Troglodytes]

I had the exact same problem with 3.3.0.  After switching it to 3.3.0, it
wouldn't bring up code completion for either MXML or ActionScript on
AdvancedDataGrid/AdvancedListBase/Advanced*.  It would bring it up for the
chart classes, though, which are also in the same SWC.  Switching it back to
3.2.0 and the code completion would work.

I found that when I switched it back and forth a few times, it started
miraculously working even for 3.3.0.  Seems like something in FB is getting
gummed up that eventually resets itself.

[flexcoders] very strange combobox problem when switching dataproviders

[Pan Troglodytes]

I'm running into something fairly perplexing.  Read the following code and
think of what you'd expect it to do when you click the change button.  Then
run it and click the change button.


http://www.adobe.com/2006/mxml";
  layout="vertical"
  creationComplete="cc()"
  >
  

  
  
  



What does it do?  Well, the combobox changes from saying "b" to "a".  The
trace says the following:
  before change:
c1.selectedIndex: 1
c1.selectedItem:  b

  after change:
c1.selectedIndex: 0
c1.selectedItem:  b

This is completely baffling.  My only guess is that somewhere in the guts of
combobox or its ancestors, it is registering for changes on a dataProvider
and not unregistering them when the dataProvider changes.  List does not
seem to suffer the same problem.

If you comment out the ArrayCollection-based version and uncomment the
Array-based version, it works as expected.

My next stop is a bug report, but I figured it'd be worth bringing up in
case anyone already knows of a bug report (kind of hard criteria to search
for) or a workaround if you need to use ArrayCollections.

[flexcoders] What determines a component's initial skin?

[Pan Troglodytes]

I've been dinking with extending PopUpButton and have run into something
that really puzzles me - how does it know to load PopUpButtonSkin by
default?  There is no code that mentions it in PopUpButton.  Is it somehow
selected based on the class name?

In my PopUpButton descendant, I want it to load a different skin by
default.  Do I just have to hardcode it into the constructor (or somewhere
else that initializes the component), or is there some more
standard/graceful way?

Hmm, I should also mention that the error I'm getting is:
TypeError: Error #1009: Cannot access a property or method of a null object

at
mx.charts.series::BubbleSeries/findDataPoints()[C:\work\flex\dmv_automation\projects\datavisualisation\src\mx\charts\series\BubbleSeries.as:933]

Which is really odd, considering I don't have a C:\work folder.  It looks
like for some reason it's showing the Adobe developer's paths.

[flexcoders] where is the FB Pro 3.0.2 datavisualization source?

[Pan Troglodytes]

I upgraded to 3.0.2 and seem to have a bit of an issue.  The last time I've
seen the datavisualization source distributed is in 3.0.0.  Sometimes when I
trace into SDK units (BubbleSeries.as at the moment), you can tell the
debugger is going to a line from a different version of the file.  Crashing
on a line that contains "var minItems:Array /* of BubbleSeriesItem */ = [];"
is kind of a dead giveaway.

Is there some way to actually get the updated source or are we screwed?

3\sdks\3.2.0\frameworks\libs\framework.swc(mx/core/Container).
GenericTestUnknown123152185967429620

First, I'm pretty sure the claim that it's Container causing the problem is
wrong, as TestStyle is a subclass of UIComponent, not a subclass of
Container.  In the help for UIComponent, there is no color style or property
listed.  Plus if you make it inherit from other things like Object,
DisplayObject, Sprite, etc., the error changes to different files, including
saying the file conflicts with itself (Declaration of style 'color'
conflicts with previous declaration in C:\dev\GenericTest\src\TestStyle.as);

If I change it to inherit="yes", it does not have a problem with it.  My
best guess is that there's something hidden and undocumented.  Doing a
search on all the SDK code found no declaration for it.  If I take out my
Style declaration and call getStyle("color") on a newly created TestStyle
object, I get 0x0B333C.  So it's getting set somewhere.

Anyone want to offer their two cents?  I'm considering filing a bug report
but I don't know exactly if this should be considered a bug (well,
definitely a bug in the compiler error text) or poor documentation or what.

[flexcoders] Anyone written a ComboBox that can take an AdvancedDataGrid as a dropdown?

[Pan Troglodytes]

I find myself in the position of really needing a ComboBox that can take an
AdvancedDataGrid descendant in the dropdownFactory.  Unfortunately, ComboBox
is pretty hardcoded to use ListBase and AdvancedListBase does not inherit
from it.  Recreating a DataGrid version of my existing ADG descendant will
be a total pain.

Unfortunately, CombBox is written in such a way that mx_internals and other
muck is threaded throughout, making it difficult if not impossible to just
clone and replace references to ListBase.

Anyone here already tilted at this windmill?

[flexcoders] My frustrations with the Adobe Bug Report system

[Pan Troglodytes]

I've put off writing this for a while out of laziness.  Going out of my way
to report bugs is already sort of outside of the scope of what I should be
working on, but I consider it very important for the quality of the
product.  And it helps that my bugs are typically answered and fixed.  But
griping about the bug report system itself seemed a little too meta.  Plus,
I kept debating on whether I should file it as a bug or email it here or dig
someone at Adobe's address up or what.

So I've settled on this, here goes.

Generally, the bug system works well.  Yes, it can be a bit frustrating to
find out if there's already a bug with the issue you're going to report.
Yes, those old bugs imported from the old DB are maddening when the subject
line makes you think they're the same.  But all in all, it works ok.  There
are really only a few things that really bug me.  Also, I'm sorry for the
terrible pun.

My main problem is with documentation.  There needs to be some explanations
as to what choices in the various combo boxes mean so that we, as users, can
more intelligently give you feedback.

Take for example the bug I'm about to enter.  I found a bug in the compiler
so that it's not parsing the code right.  This happens both in Flex Builder
and in mxmlc.  I start out and it asks "Project".  I wasn't sure on the
dropdown if it should be "ActionScript Compiler (ASC)" or "Flex Builder".  I
finally figured out I could go through Browse Projects and click on
individual projects to get descriptions of them, though not all of them had
descriptions.  Even after entering enough bugs to get a t-shirt, it took me
this long to find that.  There's plenty of room on that first page to have a
list of the projects and a short paragraph defining the scope of the project
so submitters can more easily pick the project.  FYI, I eventually decided
on ActionScript Compiler.

Next you have the Issue Type.  If you click on the little help box, you get
this help for feature requests versus minor enhancements:
 *Feature Request* A new feature to the product.  *Minor Enhancement* A new
enhancement to the product.
I had a better idea about the difference between those two BEFORE I clicked
on the help.

No matter if you choose Bug, Feature Request or Minor Enhancement, you still
get the same list of severities on the next page.  So you can choose
Bug->Enhancement/Task or you can choose Minor Enhancement->Crash Hang.  I
realize that this may just be a limitation of JIRA, but it's a little
distracting.  Along with this, minor enhancements get all the other boxes
like Discoverability, Reproducibility, Regression, etc. that really don't
apply to them.  Feature requests don't get that, but then again there's the
whole fuziness about the difference between those two things.

Now you go on to choose the Component the bug is found in.  I have never
found a page that actually gives descriptions of the various components.
And some of these leave me scratching my head.  Much as with the projects,
there should really be an easy way to get a sentence or three about each
component so you can more easily decide where to put new bugs.  Either that,
or force all bugs to go to an "unassigned" component and let the bug
reviewers sort it properly.

That's a lot of versions.  I have Flex Builder 3, the current version of FB
that is being sold on Adobe's website, and it is the seventh one on the
list.  I think.

Go to Help->Product Details->Feature Details:
Flex Builder 3
Version: 3.0.205647

I used to think I had version 3.0.2.  Only now as I'm typing this post do I
realize that I misread that and if I go here:

Help->About Adobe Flex Builder 3...  Splash screen comes up and in the
bottom right:
Version 3.0 (build 3.0.1.205647)

Well that's a bit more obvious, isn't it.  It should be, I guess, but since
there was no 3.0 on the list I though they must have some weird numbering
that meant 3.0.205647 was actually 3.0.2 builder 05647.  Not a huge quibble,
but those version numbers need to be a bit more tightened up.

Addendum.  I ju

[flexcoders] any overhead for calling simple getters?

[Pan Troglodytes]

If I have this:

private var _myvar:int;
public function get myvar():int
{
  return _myvar;
}

should I try to refer to it in other parts of the same class as _myvar, or
is myvar equally efficient?  In Delphi, you can define a property like:

FMyVar: Integer;
property MyVar:Integer read FMyVar;

and all references to MyVar automatically get optimized to FMyVar.  But I'm
wondering if Flex optimizes out the unnecessary function call represented
above.

[flexcoders] Replacement Date class?

[Pan Troglodytes]

Now that the whole ECMAScript thing has blown over, Adobe is free of being
quite so bound to it as a standard.  They've expressed interest in doing
some things that they previously shied away from because of divergence from
the standard.

Is anyone else really interested in ditching the Date class?  That thing
drives me nuts.  The number one problem is that it's an object.  So you get
something like this:

var myDate:Date = new Date(2008, 1, 1);
var myDate2:Date = myDate;
...
myDate2.month++;

It's an easy mistake to miss, especially for beginners, and it can be very
annoying to track done.  It's also a pain that you can assign values to the
time, day, month, etc. properties and it screws up data bindings and
setters/getters.  For example, if I have:

private var myDate:Date;
[Bindable] public function set myDate(value:Date):void
{
  _myDate = value;
  invalidateDisplayList();
}
public function get myDate():Date
{
  return _myDate;
}

It works great until you do something like:
  myDate.time = newDate.time;
or
  myDate.date++;


Simliar difficulties exist when using a date dropdown control.

So is it time to get a new Date class?  Perhaps a new one called DateTime
and make the old one deprecated.

What I'd love is for it to be a new primitive type (like Number, int,
Boolean) that would be stored the same way as the time property of Date and
would be manipulated through static functions of the DateTime class.
Examples:

var myDate:DateTime = DateTime.now();
trace("myDate:", myDate);
>> myDate: 1228248636245

myDate = DateTime.incHour(myDate);
myDate = DateTime.incMinute(myDate, 20);
myDate = DateTime.incMonth(myDate, -3);
myDate = DateTime.incHourUTC(myDate);
myDate = DateTime.encode(2008, 1, 1);
var hours:Number = DateTime.getHours(myDate2 - myDate1);

No more "date" or "fullYear" - use the much more intuitive "day" and
"year".  I would also like month to be one-based, but that'd probably make
enough people grumble that I'd be willing to live without it.

I dream of seeing all the existing controls and such that use Date updated
to use this code instead.  I would have already created the DateTime class
if it wasn't for how much trouble daylight savings time, leap year and
internationalization would be.

Re: [flexcoders] Can you spare 5 minutes to reproduce this 12 line bug?

[Pan Troglodytes]

Just FYI for anyone reading, the bug has been reopened and the tester has
commented.  Apparently the problem was that they were alt-tabbing between
the flex app and flex builder to see the trace output.  Once I posted the
version that outputs the null to the screen, they reproduced it.  Chalk this
up to just providing a user-unfriendly test case.

Thanks Maciek and Tom.

Re: [flexcoders] Can you spare 5 minutes to reproduce this 12 line bug?

Good to hear it's not just me.  And on such a different system, as well.  I
updated the bug with my code for the simpler test version.

Does anyone know if they read bugs that say "resolved" but have been
updated?  Should I clone the bug as a new one?

Re: [flexcoders] Can you spare 5 minutes to reproduce this 12 line bug?

[Pan Troglodytes]

Not to worry.  Clearly the bug reporter couldn't reproduce it, so I'm not
shocked that someone else can't.  All I need is for some people who CAN
reproduce it to prove that my computer doesn't somehow magically work
differently than everyone else's.  But you do make me think of something -
maybe it's dependent on Flash Player 9 and the tester only used 10.  Will
have to try testing that.

[flexcoders] Can you spare 5 minutes to reproduce this 12 line bug?

[Pan Troglodytes]

I had a bug marked "cannot reproduce", even though it's reproducible with a
12 line application for me.  It might help if a few others here will give it
a shot:

http://bugs.adobe.com/jira/browse/FLEXDMV-1908


http://www.adobe.com/2006/mxml";
  layout="vertical"
  mouseMove="trace(getQualifiedClassName(getFocus()))">
  

  
  
  



Steps to reproduce:
1. Click on the app (not on one of the components) and move the mouse
around. You will see "null" output in the console.
2. Click on the chart and move the mouse around. You will see
"mx.charts::ColumnChart" output.
3. Click on the chart again and move the mouse around. You will see "null"
output.
4. Click on the text field and move the mouse around. You will see
"mx.core::UITextField" output.
5. Repeat from step 2.

[flexcoders] need some help with an effect I made and its glitches

[Pan Troglodytes]

I'm fairly new to making effects, and it's a miracle I have any hair left.
I have created the following effect so that I can transition between various
states of a component.  The problem is that I want to reuse the same
component and not make a new one for every different screen.  So I'm making
a bitmap snapshot, sliding that one out of the way and sliding in the new
one behind it.

I have two problems.  Well, probably more once you read this code, as it's
kinda hacked together.  But the two problems that happen are:
1) when the effect starts, the original box disappears then reappears. bad
flicker.
2) when the effect ends, there is a slight hitch at the end that makes it
look jumpy

Any tips on how I can fix these two problems, or any comments on other
errors in the code?  Thanks.

[flexcoders] threading, forcing code to run in the main thread, URLLoader, etc.

[Pan Troglodytes]

I've read that Flash Player runs flex code single threaded, with the
exception of network calls and rendering calls.  So if I have a URLLoader
and I add an event to it for COMPLETE, does that event handler code get run
in the main thread, or in a separate networking thread?

If it's a separate thread, is there a way to run it in the main thread?

I'm doing some work with the f-in-box component and trying to sort out some
strange problems I'm getting.  I will go further into it if necessary, but
since most people here don't use it I was thinking a more abstracted
question would be more helpful.

Re: [flexcoders] what is a String? (default encoding question)

Thanks for checking into it, Gordon.  Too bad there's no "easy" answer, but
I'll stick with UTF-8 on the basis of ByteArray's method returning it.

Re: [flexcoders] what is a String? (default encoding question)

[Pan Troglodytes]

Thousands of rows of columnar data.

Doesn't really matter, though.  The help for both readUTF and readMultiByte
says:

Returns
String — UTF-8 encoded string.

So no matter what I do, it appears the ByteArray can only return UTF-8
anyway.  Considering this, I might as well write it to the file in UTF-8.
Of course, I suppose that internally ByteArray could read it in as something
different, then convert it to UTF-8.  So that it would read my UTF-8,
convert it to something else, then convert it back to UTF-8 and return it.
That would suck but it's impossible to tell without input from the people
who can actually see that code.  Always frustrating when I bump up against
the wall where open source becomes closed.

Do you mind asking around?  I'd hate to base my conclusions on timing tests

[flexcoders] what is a String? (default encoding question)

[Pan Troglodytes]

How is a string represented internally in Flex?  It never actually says it
in the help for String.  Is it UTF-8?  I think this because because mxml
uses utf-8 as the encoding in the ?xml directive, ByteArray seems to treat
utf-8 specially, and ByteArray.readMultiByte says the return value is a
utf-8 encoded string.

The reason I ask is because I'm reading some string data in from a binary
file and I'm trying to figure out the most CPU efficient way to put it in
the file.  I want it to be in the file in the same encoding that won't
require Flex to translate from one encoding to another when storing it in a
String variable.

Thanks.

Re: [flexcoders] force SeriesInterpolate on BubbleSeries to preserve bubble order?

[Pan Troglodytes]

Well, it's been a while but I've finally been able to get back to this.
Unfortunately, there are cases where this simply won't work.  For example:

  [Bindable] public var d:ArrayCollection = new ArrayCollection([
  new ArrayCollection([
{x:1, y:1, z:10},
{x:2, y:2, z:20},
{x:3, y:3, z:30},
]),
  new ArrayCollection([
{x:1, y:1, z:20},
{x:2, y:2, z:30},
{x:3, y:3, z:10},
])
]);

There is no way you can rearrange the second data such that it won't screw
up one of the bubbles.

I think I'm just going to have to get in there and hack at it to make it
stop trying it's "smart" bubble rearranging.

Re: [flexcoders] using callLater with setter?

Thanks Mike, but that's really what I was trying to avoid.  That's the same
as my example, only the function is anonymous instead.  I thought maybe
there was some way to get Flex to realize I wanted the setter function, not
the "property."

[flexcoders] using callLater with setter?

[Pan Troglodytes]

Is there some way to use callLater to set a property that has a setter?  So
far, all I can think of is to create a dummy function that does the setting
and pass it in the callLater:

private function setSelectedChild(viewStack:ViewStack,
newChild:Container):void
{
  viewStack.selectedChild = newChild;
}

...

callLater(setSelectedChild, [someBox]);


Any better way to do it?

Re: [flexcoders] any way to integrate 3rd-party help into FB?

[Pan Troglodytes]

Michael - Thanks for the response, but I'm a little confused on what it is
you're suggesting.  Could you give a little more explanation on the steps to
do this, from the standpoint of someone who only has FB on their machine
right now?

Will this make your help show up in the context-sensitive help and search
results as well, or only in the contents page?  Is there also a way to make
your help fully linked in, so that that objects in your help like
UIComponent or EventDispatcher can be clicked on to link to the main help?

Thanks!

[flexcoders] any way to integrate 3rd-party help into FB?

[Pan Troglodytes]

I'm been hunting around to no avail on this question.  I have created help
for my components using ASDOC.  What's the recommended procedure to get that
help to show up in FB?  Is there one?

Thanks.

[flexcoders] force SeriesInterpolate on BubbleSeries to preserve bubble order?

[Pan Troglodytes]

Following is a simplified example of what I'm running into.  Basically,
BubbleSeries doesn't preserve the order of the bubbles when you switch the
dataprovider.  Run the following program and click the left and right
buttons.


http://www.adobe.com/2006/mxml"; layout="vertical">
  

  

  

  

  

  
  
  

  



  
  


  


What happens is that the blue bubble swaps places with the green bubble and
then grows to the size of the green bubble.  What I want is for the blue
bubble to just grow in place and have the green bubble stay put.  Is there
some way I'm missing to tell the chart to pay attention to the order of the
data?  I thought maybe it had something to do with transitionRenderData, but
the documentation on it is rather ... brief.

Re: [flexcoders] possible to get bytes from a pre-existing Image?

[Pan Troglodytes]

Well, for one thing, the program is a bit up in the air on final
specifications.  Sometimes it's running off the network, other times it's
running locally.  It's just very handy to move around one single SWF and not
have to drag along all the various logos.  It's also handy for the SWF to
have a builtin list of possible logos to use.  I admit that part of the
reason is just to see if I could, and therefore to add to the toolbox of
abilities I have.

And I'm pleased to announce that I have succeeded!

There might be a better way to do it, but what I'm doing now is this:

var svg:DisplayObject = new logo;
var bd:BitmapData = new BitmapData(svg.width, svg.height);
bd.draw(svg);
var ba:ByteArray = new PNGEncoder().encode(bd);

for (var i:int = 0; i < testtext.numChildren; i++)
{
  var o:DisplayObject = testtext.getChildAt(i);
  if (o is UITextField)
  {
var r:Loader = UITextField(o).getImageReference("logo") as
Loader;
r.loadBytes(ba);
  }
}

There's the minor issue of resizing the svg before converting it to a
bitmap.  But I've made some progress on doing that.  And I'll probably
subclass Text or some component so I can get at textField without having to
iterate through the children.

Thanks to everyone for their help, and I look forward to hearing any further
suggestions, tips or mockery.  ;)

I'll try to write up a more complete example for posterity and post it as a
followup.

Re: [flexcoders] possible to get bytes from a pre-existing Image?

[Pan Troglodytes]

Excellent tip!

Well, here's what I'm trying to do.  I have logos for various companies
embedded in my SWF.  I also have various graphs where the logos will be
shown in the datatip popup.  The contents of this datatip are returned in an
SQL statement.  Why SQL?  Because this is an easy place my boss can change
the stuff so he can play with different wordings and layouts without having
me compile the Flex app every time.

So he might change the query to:

select tip = 'Results for ' from ...
or
select tip = company_name + '$' + convert(varchar, sales)

That's not exactly it, but you get the drift.  I want to be able to replace
 with the appropriate logo for the company for the point on the
graph.  It may appear anywhere in the tip text.  He could also put whatever
html markup he wanted in the tip text.

Seems to me the easiest and most flexible way would be to use a TextArea or
similiar and set the htmlText property.  But of course I need to fill in
 with whatever the correct logo image is.  I want these images to be
embedded in the SWF, so I can't just use "",
etc.

So what I have done is replace  with .  So an
example would be:

Footronics$123456

I might even go back and take out that step and just have the boss put in
"" in the first place.  That way he can control
height/width if he wants to.

Right now, I've got only as far as using a TextArea to try to work out how
to do this.  If I assign the above to htmlText, I get an ioerror.  So I set
up a handler to cloak that.  And using your tip, I find that I can
successfully do this:

var ba:ByteArrayAsset = ByteArrayAsset(new logo);

for (var i:int = 0; i < testtext.numChildren; i++)
{
  var o:DisplayObject = testtext.getChildAt(i);
  if (o is UITextField)
  {
var r:Loader = UITextField(o).getImageReference("logo") as Loader;

r.loadBytes(ba);
  }
}

Wonderful!

Well, sort of.  As I said, what I'd really like to use is SVGs.  This method
doesn't work very well with them, I'm sure due to the same problem that
forces you to only be able to use SVGs when they are embedded.  If you try
to use an SVG, you just get a continuous stream in the console log of

[SWF] C:\Documents and Settings\\My Documents\Flex Builder
3\...\bin-debug\.swf - 0 bytes after decompression

Over and over again.  Bother.  I suspect that may sink the whole
ByteArrayAsset approach.  Because I suspect I will have to embed the SVG,
then later create an object that will get make a bitmap version, THEN have
the Loader object load the bytes from it.  Somehow.  If it's even possible.

Unless someone else has a suggestion for a better way to let my boss be able
to type in all this formatted html with embedded logos that are in SVG
format.

[flexcoders] possible to get bytes from a pre-existing Image?

[Pan Troglodytes]

This question is really part of a larger ball of stuff I'm trying to
untangle.  Basically, the first part is that if I have this:

[Embed(source="logo.png")] public var logo:Class;
...
var img:Image = new Image;
img.source = logo;

Is there any way to get a ByteArray from img that can be fed to Loader?
Unfortunately, I'm stuck with Loader.  If you really want to know, I'm
trying to mess with a TextArea that has htmlText with an  tag in it.  I
want to switch the img tag to switch between different images that are
embedded in the SWF. As far as I can tell, there's no way to tell an 
tag to load an image out of the SWF.  Feel free to correct me on that.
Because of some features of the environment, I really want to embed the
images and not load them from the local file system or over the network.

Eventually, I actually want to replace the PNG with an SVG.  This is part of
why I'm wanting to have the files embedded.  But I know this will bring
further challenges, as SVG is a vector format and I will have to get a
raster rendering of the SVG at a certain size before I can ever expect to
feed it to Loader.  But I'm trying to take it one giant hurdle at a time.

Any thoughts, other than that I'm insane to do such a thing?

Re: [flexcoders] Re: Styling AdvancedDataGrid's header

[Pan Troglodytes]

I might have to see some code before I can figure it out.  But out of
curiosity, when you say you "override" headerSeparatorSkin, do you mean you
just do something like:



or are you talking about doing something in the actual actionscript code?

Re: [flexcoders] Re: Styling AdvancedDataGrid's header

[Pan Troglodytes]

I THINK I know what you're talking about.  You mean the grey line that
separates each column, right?  What you're wanting is a line that goes all
the way from the bottom-left of the first column header to the bottom-right
of the last column header, right?  If not, please post a doctored screenshot
of how you want the header to look.

If so, I think you'll need to make your own headerSeparatorSkin for ADG.
This is what is in the default skin, DataGridHeaderSeparator.

override protected function updateDisplayList(w:Number, h:Number):void
{
  super.updateDisplayList(w, h);
  var g:Graphics = graphics;

  g.clear();

  // Highlight
  g.lineStyle(1, 0xFF, 0.5);
  g.moveTo(0, 0);
  g.lineTo(0, h);
  g.lineStyle(1, getStyle("borderColor"));
  g.moveTo(1, 0);
  g.lineTo(1, h);
}

I made my own subclass of ProgrammaticSkin that just had nothing in its
updateDisplayList.  That gave me no separator at all.  I'm sure you could
get it to do just what you want.  You're still left with the default border
around the entire block of columns drawn by the grid.  There's probably
another skin you could replace to get rid of that if it's a problem.

Re: [flexcoders] Overriding parent's style in custom component

[Pan Troglodytes]

This might be kind of a hack, but you could override setStyle, catch the
backgroundcolor style being set and not call the super for it.

Re: [flexcoders] Drag and Drop question

[Pan Troglodytes]

I believe you're going to need to handle the drop events yourself and not
use the dropEnabled=true setting.  When you do that, by default drop is
denied and you have to tell it to allow it, like in the dragEnter event.
For example:

private function dragEnterHandler(e:DragEvent):void
{
  DragManager.acceptDragDrop(UIComponent(e.currentTarget));
  DragManager.showFeedback(DragManager.COPY);
}

[flexcoders] any way to use embedded image in htmlText?

[Pan Troglodytes]

The answer to this is probably going to be "no", but I figure it's worth a
shot.

I have a number of images embedded into my flash application.  I would like
to allow the user to type some html that would include an  tag that
references those images.  That would then get applied to a UITextField's
htmlText property.  Is there any way to do this, or are you stuck with
either loading images for htmlText off the network or off the hard drive?

Re: [flexcoders] AdvancedDataGrid: Exclude last row from sorting

[Pan Troglodytes]

Glad you got the result you were looking for.  Yes, it does kind of suck
that they made the sorting method so simple.  The problem is that that part
of the code isn't grid code, it's ICollectionView code.  It winds up using
SortFields, which are very unaware of any griddish concerns.  It's a great
way to do it, from a code design point of view.  But sometimes it can throw
a monkey wrench into practical applications.

Re: [flexcoders] Re: Styling AdvancedDataGrid's header

[Pan Troglodytes]

Yeah, I think your could subclass it and override updateDisplayList for what
you're needing.  Check this out and see if it does what you need:

package nes
{
  import mx.controls.advancedDataGridClasses.AdvancedDataGridHeaderRenderer;

  public class AdvancedDataGridHeaderRendererExt extends
AdvancedDataGridHeaderRenderer
  {
override protected function updateDisplayList(unscaledWidth:Number,

unscaledHeight:Number):void
{
  super.updateDisplayList(unscaledWidth, unscaledHeight);

  graphics.moveTo(0, unscaledHeight);
  graphics.lineStyle(2, 0xFF);
  graphics.lineTo(unscaledWidth, unscaledHeight);
}
  }
}

Re: [flexcoders] Issue with runtime adding of axis labels in DateTimeAxis

Off the top of my head, I can't think of an easy answer.  But if you could

Check out the help for AdvancedDataGridHeaderRenderer.  That's what the grid

Re: [flexcoders] AdvancedDataGrid: Exclude last row from sorting

[Pan Troglodytes]

Sorry Dan, my brain must not have been fully in gear.  You do need to check
the columns sort order:

if (obj1.summaryRow)
  return col1.sortDescending ? -1 : 1
else if (obj2.summaryRow)
  return col1.sortDescending ? 1 : -1
else if (obj1.value < obj2.value)
  return -1
else if (obj1.value > obj2.value)
  return 1
else
  return 0;

Where col1 is the id of the column being sorted.  That should (hopefully) do
it.

Re: [flexcoders] tree control child node color

First off, which menu do you mean at the website?  I only saw a menu at the
top, and all the nodes were all one color as far as I can tell.

But if you just wanted to specific a lit of colors for different levels, I
believe the depthColors style of Tree would be what you wanted.

Re: [flexcoders] Flex Charting Issue with Data Effects

[Pan Troglodytes]

Okay, I think I figured it out.  I had the same problem in the 3.1 SDK.  You
were definitely being stumped because you didn't have the Pro source code.
I went ahead and created a bug and entered the reason it's broken and how
you can go about working around it.  If you vote for the issue, there's more
of a chance it will be fixed in a future SDK release.

Re: [flexcoders] Date field in either arraycollection or datagrid

[Pan Troglodytes]

For #2, look at ArrayCollection.sort.  You can create a sort object and use
a slightly modified version of your date_sortCompareFunc for the
compareFunction of the Sort object.

I've never really found a good way to do #1, so I'd be interested in that if
you or anyone else finds a way.

Re: [flexcoders] Custom vertical axis line on plot chart

[Pan Troglodytes]

There are several ways you could go about doing it, though nothing built in
to support it.

One way would be to make your data so that 30 is actually 0 in the
underlying data.  You'd write an axis label function that would add 30 to
the values for labelling.  If you wanted datahints, you'd have to write a
function to do the same for them.  Then you'd set the major tick interval
really high so that you'd only ever get a single grid line at your fake 0
point.

Another way would be to create a ChartElement that just draws a line at 30
and stick it in the BackgroundElements, along with a GridLines that is set
to horizontal only (if thats what you want).

Re: [flexcoders] Bug ? IE & FireFox Menubar

[Pan Troglodytes]

I believe you're just running into how different browsers handle embedded
flash objects.  Once you click on a flash app, firefox generally lets it
have every keystroke after that until you actually click somewhere outside
it.  IE is less permissive and continues to listen for keystrokes even when
a flash app is focused.  Once you click outside a flash app in either
browser, your browser no longer receives keystroke messages because it's no
longer focused.

Re: [flexcoders] How to do a State Change Area Chart with Time Series State Change Source Data?

[Pan Troglodytes]

This shouldn't really be hard at all.  Have you actually tried it and are
running into difficulties?  You need to make sure your x values are in the
format that Date() likes, and if using a DateTimeAxis doesn't work, you can
use a LinearAxis and a custom axis label function.  If you want a stairstep
instead of a straight line between points, that's also possible with a
certain property/style of the series.

Re: [flexcoders] Browser Bug ? Display 2 scrollbars

[Pan Troglodytes]

It would probably help a lot if you can post a small test app the shows what
you're talking about.  Keep it as simple as possible to illustrate your
problem.

But my first instinct is that it's kind of an age-old problem in programming
with scrollbars.  Say you have an element that is 500 pixels wide, just wide
enough to show everything it contains.  Then it gets a lot of info in it,
which causes it to need a vertical scrollbar.  Well, that scrollbar then
steals some width from that 500, so that now the element can only be, say,
484 pixels wide because there's a scrollbar taking up the next 16 pixels.
Well, now if you have scrollbars set to automatically pop up when the
element isn't wide enough to display the text width, the horizontal
scrollbar shows up, too.

The fix for this in flex is to set the horizontal widths as a % of the
parent's width.  That way when the vertical scrollbar pops up, the element
and hence its children will resize to be smaller to accomodate the
scrollbar.

If this isn't clear, post your example and I can show you the changes to fix
it.

Re: [flexcoders] Not able to capture event dispached from custom state override - what's wrong?

[Pan Troglodytes]

You need to register your event handler with the object actually dispatching
events.


...
mytest.addEventListener("testEvent", handleIt)

Re: [flexcoders] AdvancedDataGrid: Exclude last row from sorting

[Pan Troglodytes]

Yes, it's fairly easy to do with a custom sort function.  Here is an example
function that assumes you set a "summaryRow" property on the last row
object:

  private function compareWithSummary(obj1:Object, obj2:Object):int
  {
if (obj1.summaryRow)
  return -1
else if (obj2.summaryRow)
  return 1
else if (obj1.fieldbeingsorted < obj2.fieldbeingsorted)
  return -1
else if (obj1.fieldbeingsorted > obj2.fieldbeingsorted)
  return 1
else
  return 0;
  }

Where "fieldbeingsorted" is the field for that column that would otherwise
be sorting on.  For example, if you had



then fieldbeingsorted would be customerName.  You'd need to make a different
compare function for each column in the grid, since Flex doesn't pass in the
column name to the sort compare function.
