[flexcoders] Synchronous HTTPService possible? Need to verify edit inside of Edit Event..

[Alex]

Quick question,


   I'm trying to devise a table-edit view of a set of database tables,
and am successfully pulling records using e4x etc.

   At the cell-edition stage, I'm capturing an "itemEditEnd" event on my
DataGrid, and that's going well also.

   My question however, surrounds actual edition, and the cancellation of
an edit event.

   The code should look like this:

private function editHandler( e:DataGRidEvent ):void{
   if( e.reason == DataGridEventReason.CANCELLED )
   return;

// get the new input
   var newData:String = TextInput(
e.currentTarget.itemEditorInstance).text;

// request the edit
??

if( "edit was bad" ){
 e.preventDefault();
 // TextInput( dataGrid.itemEditorInstance ).errorString = "Invalid
input";
}
}


"Requesting the edit" above, involves using HTTPService to send the edit
request to the server, which will respond with OK, or NOT OK.  How can I
"wait" for an HTTPService request inside of that function, so that I can
call e.preventDefault() if required?  AFAIK, the HTTPService only works
with a callback-type model?

Can I synchronize and wait on a lock like in Java in this case?

Much appreciated.

I create simple charting using flex in my website,I have a problem regarding 
candlestick chart , its seems that first and end value of the drawing cut in

That would make sense to me.  UIComponents don't like having the parent
chain broken by non-UIComponents.

Sorry gents, can't post the code, for an NDA project.

Regardint the Label component... it's weird.  If I add him to
rawChildren, no problem.  If I add him to my background (the Sprite you
suggested be the container Michael), it gets pissed during measurement;
something about anti-aliasing being null.  I'm not removing it all; my
guess is, because the parent isn't actually in a UIComponent, or perhaps
he's not yet added to the DisplayList during measure, that somehow ticks
it off? 

:: shrugs ::

rawChildren, for now, works fine as does the extending of the creating
of the contentPane to shove my custom chrome content backwards.

I don't have a problem, Jesse asked a question, I threw some code at him
to try and that is that. 

I don't want to create a second child and hack that way, I want a
rawChild that is it. 

I was just responding to him, what I am doing works for the container I

RE: [flexcoders] Data binding: How to detect data change has happened?

[Alex Harui]

You can listen to events from the collection as well.

 

dg.addEventListener(CollectionEvent.COLLECTION_CHANGE, ...)

 

Check out the doc on that event.

Thanks Alex,

 

I'm not looking for when the dataSource is assigned, it more the second

In the mx.controls.DataGrid, the dataProvider property is not a var, it
is a get/set function pair.  When someone assigns dataProvider, the set
function is called so we know it changed.

 

All dataProviders must implement ICollectionView or will be wrapped in
an ICollectionView.  When you change things in an ICollectionView, the
contract is the ICollectionView will spew events which the DataGrid is
listening for.

 

There is no general property watching in AS, so you have to define
contracts and use events and whatnot.

[flexcoders] Re: Chrome behind content?

[Paul DeCoursey]

Could you post the code of the problem?  I think I understand the
problem but I need to see what you are doing to help with the solution.

I understand the background in front of things now, but I don't think
that it was the wrong way to code chrome.  It fits too narrow a use case.

That is precisely what I have created, in fact my ideas came from
looking at how other components worked.  My issue was different.  I
was using the graphics class to draw on the Canvas in addition to
having a few child elements.  The problem came when I set the
background.  It put the background over my drawing, which in my
opinion is wrong and in fact a bug.  When I looked at how the code was
working I saw that I needed to implement the same kind of thing for my
component. I created a content page that the drawing and children were
in, and then the background could be set without interfering with my
drawing.

It's a similar approach, but I have more control over the parts.

RE: [flexcoders] Displaying single bar/column (Type: 100%)

[Ely Greenfield]

 
 
More detail would be helpful to understand exactly what you want, vs.
what you're seeing. Please be as specific and pedantic as possible.
 
If you want to get rid of the surrounding chart graphics, you can:
 
1) zero out the backgroundElements array
2) assign axisRenderers that hide all of their elements.  I don't
remember exactly which set of styles/properties you need, but if you
look at the APIs for AxisRenderer it should be apparent. something like:

You certainly know the charting components BarSeries or
ColumnSeries They are great, if you need exactly this kind of
view. But I am currently in a bit of a problem, because I need a
column-/bar component which only is able to show ONE bar or column for
a series of data.
You probably say: 'Easy thing!' - just use bar-/columnseries with type
set to 100% and you will get only one bar with all data... but in
fact, you also get the cartesian chart around it, which annoys me. I
just want to have one simple Bar/Column which is able to show me
different values (Type 100%) without anything. I tried already to use
the "IBar" Interface, but no luck. 
Someone told me I have to have a look in the samples.zip of FDS (1.0)?
for an example 'Sector' but have not found it

Any help or hint is really appreciated...

btw, i've done the same a few months ago and found the learing curve to 
be very smooth (coming from a c++/c# background -- and returning there 
now :)). AS3 is close enough to other c-syntax-like (garbage collected) 
languages. Flex Builder close enough to other common IDEs I've used before.

I got started by just having a look at the quick starts at the adobe 
site (http://www.adobe.com/devnet/flex/?tab:quickstart=1). Adobe also 
provides the source code for a lot of the basic controls, having a look 
at that also helped me. Also the adobe docs/help are fairly good and 
complete all in all.

Anyways, have a nice Sunday (or what's left of it)

Paul > I'm not really sure what that is all about, Background isn't chrome

is background. Children need to be in front of background.

I have a spec where I need another background behind the view children and
in front of the border.

Trust me, I have 1000's of hours of investigation into this. This applies if
you are doing low level coding in the framework.

Not to mention, when the container holds more then 1 view child, the
children get put into a content pane. It is impossible to get something
behind child 0 without using this hack.

Jesse,

with the text area, after removing it from the display list did you set;

textField = null;

??

do you ever get here? In case you don't know: you can set breakpoints 
when using FlexBuilder. There trace(string) function is also handy for 
debugging?

I've tried this code and it works as expected, what are you doing different?

FooClass.as:

package {
public class FooClass   {
public var Callback :Function = null;
public function Fire() :void {
if (Callback != null) {
Callback(42);
}
}
}

[flexcoders] Dynamically create widgets? (Flex noob)

[Alex]

Hi there,

  Is there any way to dynamically load windows whilst inside a given
state?

  For example, replicate the behavior in Java where we do:

  JFrame f = new JFrame();
  f.setSize( 100, 100 );
  f.setVisible( true );

  Is there a Component.create( ) type of method?

Thanks Always!
Alex

[flexcoders] Re: Function pointers? (Solved)

[Alex]

NM I got it, seems it hasn't actually instantiated objects, even
though it's in a creationComplete block!  Adding the callback
attribute directly into the actual tag worked.

[flexcoders] Re: Function pointers?

[Alex]

Hrm,

  Seems that what may have seemed intuitive, throws this error:

TypeError: Error #1009: Cannot access a property or method of a null
object reference.

At this line

fisheye.callback = menuSelect;

Any ideas?

[flexcoders] Re: Function pointers?

[Alex]

Thanks Ben,

  I've been poking through the docs, I just have no concept of what
each element is called yet - jumping in head first with tons of heavy
programming experience, but zero Flash/AS/Flex experience. Your
answers here are incredibly appreciated

  Back on topic..

1. I've added 

public var callback:Function = null;

..to the object class.  Further, at the point where the callback
object should fire, I've added this code:

if( callback != null )
  callback( 3 );

2. In the main app where I'm creating this object, I've added, inside
of a "creationComplete" block, the following:

customObject.callback = menuSelect;

private function menuSelect( index:int ):void{
   
}
  

Unfortunately, it doesn't seem to fire..

you can pass functions as arguments or assign to properties just as you

eg.

private function foo(callback :Function = null) :void {
   callback();
}

It is possible to define a public variable of type Function

are preferred in AS3/Flex 2 though

Paul, if you look in mx.containers.Container, you can see how they
override and abstract the DisplayList API so that you have 2 types of
children; raw and regular.  This allows you to have "those you put in
Canvas" and "those that make Panel".  For example, the title bar, close
button, title, etc. are NOT something you want inside your Panel container
to interact with your children.  If you put a CheckBox control into a Panel,
you would expect only 1 child to be in your container (numChildren,

others to use without "knowing" how your child setup works.

You're right. In Tomcat you must to install JOTM and use a file "context.xml"

You can see the test drive example from Christophe Coenraets to see an

[flexcoders] Re: Flex CacheKeyUtils error on JBoss Portal

[johan.wasserman]

Is there no one out there that can give any response to the error?  I 
have searched Adobe Labs for any groups or comunities on the Flex Tag 
library to no avail.  Is there any other way to intigrate Flex into 
JBoss portal other than using the Flex taglibs?  I desperately need to 
prsent flex apps as portlets on JBoss portal.

[flexcoders] Re: Chrome behind content?

[Paul DeCoursey]

I'm not really sure what that is all about, Background isn't chrome it
is background.  Children need to be in front of background.  I know at
one point I was having trouble with a background rendering over some
graphical elements that I had.  So to fix that I did my graphical
elements on a child item, that way the canvas background rendered
behind my content. I'm not sure you have the same issue, but perhaps
you could use that technique to solve your issue.  Create a container
with two children, one for display elements and one for chrome.  Add
the chrome first and the children second and your children will be
above the chrome.

Also this really sounds like a bug.  You should report it.

Re: [flexcoders] Chrome behind content?

[Michael Schmalle]

Well man, this is a hack and it works though :)

I had the same issue and so far this hasn't blown up in my face.

Try this on for size... the backgroundInstance is what is going behind the
content but infront of the border.

   override mx_internal function createContentPane():void
   {
   super.createContentPane();

   if (contentPane &&
   backgroundInstance)
   {
   var border:DisplayObject = rawChildren.getChildByName("border");
   var index:Number = (border) ? 0 : -1;

   rawChildren.setChildIndex(DisplayObject(backgroundInstance),
index + 1);
   rawChildren.setChildIndex(contentPane, index + 2);
   }
   }

Peace, Mike

The hack, for now, is to NOT have my chrome draw a background.  If it
doesn't, I can click on children just fine.  That, however, sucks because I

Suggestions?

[flexcoders] Data binding: How to detect data change has happened?

[Greg McCreath]

Hi all,

 

I'm interested to know how in an object with a data binding I can detect
a change in the datasource.

 

For example, if I were to develop (say) a custom datagrid that (in MXML)
a user of that datagrid can set the datasource property to something
like "{blah.blahblah}".

 

Then, in that custom datagrid how do I detect that that blah.blahblah
has changed and take some action when it does?  In the custom component
I do not want to know of the existence of blah.blahblah, just that it
has changed and what its new value is.

 

All help appreciated.

 

Greg.
