[flexcoders] Application file doesn't launch

[Kevin]

Does anyone know the reason an flex application would not launch and  
instead just fail silently in Eclipse?

I am trying to run the main application file and the launcher starts  
up, but then stops and nothing is launched in the browser.  However,  
if I create a new blank test project, then everything works fine.   
There must be something in this project that is causing it to not  
launch.

I am trying to rebuild a project from my SVN after a hard drive crash.

Thanks, Kevin

RE: [flexcoders] Re: Treat a string as a reference to an object?

[Gordon Smith]

I'm not sure what obj1, obj2, etc. are in your example. But if they're
instance variables in your class, then
 
obj1.foo
this.obj1.foo
this.obj1["foo"]
this["obj1"].foo
this["obj1"]["foo"]
 
are all equivalent. So you can look up a property by name on an object
by name as
 
this[object_name][property_name]
 
Keep in mind that when you write a class in MXML, the id's of MXML tags
become instance variables of the class. For example, if you have
 

 
then
 
this["b"]["label"]
 
will be "OK".

Thanks Gordon,

Following your example, can you create the name of the root object 
dynamically and have it be treated as a valid property reference at 
runtime? 

example: If i wanted obj1.foo, obj2.foo, or objsome_string.foo

RE: [flexcoders] My problems with Events

[Gordon Smith]

If you're listening for MouseEvent.CLICK, you're not going to get it
when the mouse pointer simply enters anything. You get it only when you
click the mouse button!
 
If you want to detect entering and leaving sprites, use
MouseEvent.ROLL_OVER and MouseEvent.ROLL_OUT.

Hi,
I'm doing a little application example while learning different
topics. I'm in the Events topic now ,which I'm still struggling to
understand (Capture, bubble phases). The application is very simple
having a display list as follows.
MainSprite
ChildSprite
TextField

The Child Sprite has a certain dimension width, height. It contains
the Text Field, width also dimension set smaller than Child Sprite.
I've added an EventListener to the Child Sprite, the Event type is
CLICK. The event handler will change the backgroung of the Child Sprite.

The problem is that the event is triggered only if the mouse pointer
enters the TextFiled area, which is a non expected behaviour. The
Event should be dispatched as soon as the mouse pointer enters the
Child Sprite area. 
Can please someone explain brievely if this is the correct behaviour
and what should I do to trigger the handler event as soon as the mouse
pointer enters the Child Sprite are, not until it goes the the text
field area.
Thanks

RE: [flexcoders] How to use UIComponentDescriptor "type" property

Lets say that your custom component class is MyComponent. Are you trying
to determine whether the descriptor is for any instance of MyComponent,
or for a particular instance of MyComponent?
 
If it is the latter, I would do
 
if (someDescriptor.type == MyComponent)
 
rather than
 
if (someDescriptor.type.toString() == "class MyComponent")
 
In other words, use MyComponent as a Class literal value.
 
If it is the former, do
 
if (someDescriptor == myComponentInstance.descriptor)

I want to use the 'type' property of the UIComponentDescriptor object
to find out if the component that it is describing is my custom
component.

The only way I have been able to do this so far is by calling
toString() on the 'type' property and doing a string compare with the
name of my custom component. This seems all wrong. It seems like I
should be able to do a compare with the 'type' property as is, or use
the 'is' operator or something, but so far I have been unsuccessful in
my attempts.

Any thoughts? I think I am missing something basic and obvious on
this one. :-)

RE: [flexcoders] Question about delete

[Gordon Smith]

Just to be pedantically correct...
 
In AS3 you can't destroy any object... only the garbage collector can. But by 
nulling the (only) var referring to your Podz instance, it becomes elegible for 
garbage collection at some point in the future.
 
Setting the var to null is not the only way to release the reference to the 
Podz instance.. Setting it to refer to a second Podz instance would make the 
first instance eligible to be GCd. Or if the var was of type Object or *, you 
could set it to 17 or "abc", but null is the obvious convention.
 
And if the var is a local variable, then that var automatically goes out of 
scope at the end of the function (not at the end of its block!) and the Podz 
instance becomes GC-eligible then.

RE: [flexcoders] Re: Is there any way to call super.super.method in AS3?

[Gordon Smith]

Alex meant to say "If a method is overridden, you can NOT skip around
the override like you can in some other languages." And you can't
directly, with super.super. But you can, indirectly.
 
The way the framework codes around the lack of super.super is to use the
following pattern:
 
class A
{
function f()
{
doSomething();
}
}
 
class B extends A
{
// This will hide A's f()
override function f()
{
doSomethingElse();
}
 
// But this makes A's f() available as B's $f
final function $f()
{
super.f();
}
}
 
class C extends B
{
override function f()
{
$f(); // call A's f() -- which is effectively super.super.f()
}
}
 
Using $ in the name is just a convention which indicates that you're
getting the original, un-overridden function. We also make it final to
guarantee that it remains un-overridden.

Yes, exactly how you wrote it.  However in order to have the top level
function actually run before adding methods etc... with level 2 you need
to call super.myMethod(); from B or not override it at all in B to be
able to access it's functionality! from C.  In other words, if you
override a function and then try to override it again in a class
extending the one with the original override and don't call the super
version in the intermediate class then you end up with an empty function
at the end.

Re: [flexcoders] Re: Accessing the illusive stage Object through sprite (a near impossible feat)

[quote by Troy Gilbert]
"Not in the constructor."

Assuming your SWF is being loaded into another SWF.

[quote by Alex Harui]
"The stage should be there for the root class right away."

If your SWF is the main (root) SWF, then Alex is correct. Although listening
for ADDED_TO_STAGE would be the safest way since it means never having to
refactor your code if it ever is loaded by another SWF.

Also, ADDED_TO_STAGE is only triggered if the loaded SWF is added to the
display list. If you load the SWF and do nothing with it, the event will
never fire and the SWF won't have a stage property value.

  Not in the constructor. During the constructor of a Sprite it has not
yet been added. What you need to do in your constructor is:

this.addEventListener(Event.ADDED_TO_STAGE, handleAddedToStage);

valid. If you need to know when you're removed from the stage (which, AFAIK,
won't happen to your root class in an AS3 project, but will happen to other
classes, potentially) is to listen for REMOVED_FROM_STAGE.

If you wanna know when this.parent is valid, listen for Event.ADDED.

ok,

just realized that you can accomplish something similar by using

circumstances and is quite hacky.

i need to destroy children when the condition changes, to avoid
parameter problems... but still. that only leaves me with binding
issues.

OTOH, the ideal way would be to create a custom component that
implements IRepeater so that containers don't add it, and then play
with createChildrenFromDescriptors and such.

i just gave the latter a try and got it kinda working, but it would

it. i give up.

You could setup a hyperlink by creating a custom cellrenderer, but the
easier way would be to listen for the change event. That will give you the
rowIndex and columnIndex so you can get the data for the cell pressed and
execute the navigateToURL (or whatever other code) based on that data.

Re: [flexcoders] TabNavigator/ToggleButtonBar Style conflict

[Derek Vadneau]

Thank you for the workaround, it will work great for my project.

Now, I can maybe understand that it's perhaps not a bug but it definitely is
a shortcoming of the style system and docs.

There is no mention of Tab in the docs. I had to go look for the class in
the SDK just to know how you got that.

Also, other than searching through the component code, the only method given
for setting the styles on the components is what I gave. In fact I got that
from the Adobe style explorer app.

And if I had a TabBar component in my project (I don't but bare with me) it
would take on the style I set with Tab, which I would expect, but not
necessarily want.

When I explicitly set a style for a component I expect that it takes on that
style. I understand what you mean by TypeSelectors and inheritance, but that
just means the style system (or code implementing it) might be flawed. When
I set a style for ToggleButtonBar, I would expect ALL instances of
ToggleButtonBar to take on that style. However, in the case of the
TabNavigator (and any other component that contains other components) when
there is a way to explicitly affect a child instance within, that should be
honoured.

Going back to my code, I would expect that the text in each TabNavigator tab
might be red (because of the ToggleButtonBar styles), but they aren't. Only
the first and last are. And I would expect that the cornerRadius set by the
TabNavigator style be honoured. If I set the cornerRadius as you mention in
mytoggleButtonBarFirstButtonStyle, I would expect the TabNavigator style to
override that style. Why? Because that style was explicitly set for the
TabNavigator's children.

A simplified example, but just to show where my head is at: Take an HTML
page with CSS. If I have a list item of an unordered list and specify a
style for li to be color:#FF and font-weight:bold, the text would be red
and bold. If I set a particular list item to use a class style where the
color is #FF, that one list item would be blue and bold. That would be
my expectation anyhow.

Hopefully you get my meaning.

Thanks for you time!

  Hi,

The reason it doesn't work is because TypeSelectors order in inheritance.

Solves your Problem. This is not a bug.

Since you are setting a firstButtonStyleName on an actual selector,
TabNavigator will not pick it up since it is undefined to begin with and now
defined on the super class TypeSelector of TabBar.

If you set

.mytoggleButtonBarFirstButtonStyle {color: #FF;cornerRadius: 0;}

You will see that changes the radius of the first tab button.

Re: [flexcoders] Error #1009 - Problem running swf on production server

[Flexing...]

This is basically a null pointer exception.
In your itemrenderer you must be trying to access the variable of an  
object to probably display the value.

The object in this case is null.
You need to add nullity check in your code.

Re: [flexcoders] Re: Accessing the illusive stage Object through sprite (a near impossible feat)

[Troy Gilbert]

Not in the constructor. During the constructor of a Sprite it has not yet
been added. What you need to do in your constructor is:

this.addEventListener(Event.ADDED_TO_STAGE, handleAddedToStage);

And then in handleAddedToStage() method of your class this.stage will be
valid. If you need to know when you're removed from the stage (which, AFAIK,
won't happen to your root class in an AS3 project, but will happen to other
classes, potentially) is to listen for REMOVED_FROM_STAGE.

If you wanna know when this.parent is valid, listen for Event.ADDED.

Michael,

Thanks so much, where was that event hiding? I was using a hackish
timer to do the job. However, your solution doesn't work from within
the class that I create (haven't tried outside yet). Is there a way
to do this all from inside the class I am using, or does the event
listener have to sit outside the class?

Really, I think it would have been better, but maybe it's not even
possible to make the constructor function of classes automatically
have access to the stage object on instantiation?

Also, to trap keyboard events the only way I could make it works is
the following:

stage.focus = this.parent;
this.stage.addEventListener(KeyboardEvent.KEY_DOWN,keyHandler);
this.stage.addEventListener(KeyboardEvent.KEY_UP,keyHandler);

It would seem that the Flash designers/implementors thought that
perhaps the ubiquity of the Flash plug-in for deployed web browsers is
such that unfettered server access could promote a market for
bot/drone developers and privacy eroding spyware/malware.

I can't really see it myself. I guess they thought that Flash would
not be as widely deployed if there was any sort of media noise related
to security problems it might cause for the user.

Any standard HTTP server or mail, or DNS, or other server on its
standard (low) port. The only option seems to be to write your own
generic TCP proxy, then host it on your own bandwidth... sigh.

That certainly does cut down the usefulness of Flash as an application
platform. 

In the past, I've deployed a Flex app on XULRunner and used the XPCOM
socket apis. Very fragile, hard to debug, and seemingly pointless.

I see it as a show-stopper (in consideration of Flash) for small
projects that require decent access to external resources (sans
hosting bandwidth)... I just have to use another language for those
projects.

Hi all,

The component below gets to instantiate its chid correctly but it
doesn't show up in the displaylist.

any clues??

package foo.conditionals
{
import mx.containers.HBox;

/**
 *
 * Does not support changing the condition property at runtime yet
 *
 * @author abucchi
 *
 */
public class ConditionalContainer extends HBox
{

private var _condition:Boolean;

public function get condition():Boolean
{
return _condition;
}

public function set condition( value:Boolean ):void
{
_condition = value;
}

override public function createComponentsFromDescriptors(
recurse:Boolean = true ):void
{

if ( childDescriptors.length == 0 )
return; // no children specified

if ( condition ) // condition met, create first child
{
createComponentFromDescriptor( 
childDescriptors[0] , recurse );
}
else if ( childDescriptors.length == 2 ) // not met, 
create second
child if specified
{
createComponentFromDescriptor( 
childDescriptors[1] , recurse );
}

}   

}

}

[flexcoders] Re: Brainstorming; Dynamic Conditionals in MXML

[Aldo Bucchi]

ok,

just realized that you can accomplish something similar by using
navigators... just set creationPolicy="auto" and conditionally set the
selectedIndex... only it will just work under some particular
circumstances and is quite hacky.

i need to destroy children when the condition changes, to avoid
parameter problems... but still. that only leaves me with binding
issues.

OTOH, the ideal way would be to create a custom component that
implements IRepeater so that containers don't add it, and then play
with createChildrenFromDescriptors and such.

i just gave the latter a try and got it kinda working, but it would
take too much time to make it work with bindings and stabilize
it. i give up.

c'mon adobe guys!
you can do it ;)

Yep... thought of that... but if your label widths change that labelGap

[flexcoders] Hyperlink in datagrid

Hi,
   
  I am displaying some data in a datagrid where dataprovider is a XML file. 
Now, I have a requirement where I need to provide a hyperlink on each data cell 
of the datagrid, so that clicking on the item can take me to some other page. 
e.g. 
   
   
  --
  column1column2 
  -
   FailPass
   FailPass
  --
   
  Clicking on fail/pass should display the log results.
   
  Any idea, how to provide the hyperlink?

[flexcoders] Re: Dynamic LineSeries based upon Array Collection?

[Aaron Wright]

You set the data provider of the series to nothing.
myService.lastResult is not set to anything until the HTTPService has
returned.

I normally call send(), and then in a seperate function handle the
complete event. Then the the lastResult will be set.

I suppose you could data bind the data provider of the line series to
the lastResult of the HTTPService via BindingUtils.

[flexcoders] Re: Deploying Flex app to web server

[arieljake]

I think this is happening because you are trying to access a property 
or method of a null object reference.

:) I couldn't help myself.

But really, if this is happening after a deploy, maybe one of your web 
service calls or server data calls are failing and in your code you are 
not checking for valid data before operating on it. Make sure the paths 
you are using work on the server too, and if your data calls are to web 
pages that can be viewed in a browser directly, use a browser to view 
them to make sure there are no errors preventing valid data from being 
returned in the production environment.

Sorry, didn't read the whole thing.

 

The stage should be there for the root class right away.

Michael, 

Thanks so much, where was that event hiding? I was using a hackish

[flexcoders] Brainstorming; Dynamic Conditionals in MXML

Hi Guys,

Has anyone flirted with the idea of creating MXML
conditional-structure components that can be used to dynamically
generate interfaces??

just to be more graphical... something like this





  












it just makes a lot of sense...
any ideas

[flexcoders] Under flex Builder, is it possible to step into an app loaded by SWFLoader?

[Tracy Spratt]

For one of our clients, we make heavy use of SWFLoader to load
applications into a shell app.

This works very well but is hard to debug, since I haven't found any way
to debug the loaded apps (except for trace, of course).

Is it even possible to debug apps loaded this way?

Running the loaded apps alone is problematic, since they depend on data
(xml) passed in from the shell.  I could default this data for testing
purposes, but am hoping for some magic instead!

I have not explored modules yet.  Can you step into them in the FB
debugger?

[flexcoders] Dynamic LineSeries based upon Array Collection?

[tedgies]

Has anyone had any success in creating a chart with a series that 
you can add to at runtime?  (Like Yahoo finance charts 2.0).  I 
haven't yet seen an example where the LinSeries is based upon a 
changing (growing) set of external xml data files.  Below i paste a 
snippet where i try to for loop through an Array Collection and 
create a separate httpservice call for each dataset (each baseball 
player).  The httpservice URL is created dynamically based upon the 
arraycollection.  I don't get any errors, but my chart will not 
paint my data.  I think my problem is in:

newSeries.dataProvider = myService.lastResult.item;

thanks,
Ted

  
   

RE: [flexcoders] Re: Charts and Business day axis

[Ely Greenfield]

 

 

 

The DateTimeAxis doesn't currently do business weeks. It's something
we're looking at adding for the next version.

 

In the meantime, you have three choice, in increasing order of
difficulty:

 

1)  Use a category axis, and deal with tiny labels

2)  Use a category axis, set dropLabels to true on your
axisRenderer, and accept that fact that you can't control the amount of
time between labels.

3)  Write a custom axis that acts like a category axis, but
generates labels based on your heuristic (i.e., only on the first of
each month, etc). You might be able to do this by extending the existing
category axis.

4)  Write a custom axis that acts like a date/time axis but drops
weekends.  This would be difficult to do with the existing date time
axis as a base class.

 

 

Ely.

Re: [flexcoders] Empty branch in a TREE - show folder instead of file icon?

Run this method over your XML before using it as you dataProvider.
Probably a better way to do but it worked for me in similar situation.

var myXMLWithBranches:XML=iconizeXML(myOriginalXML);
//---



private function iconizeXML(xmlobj:XML):XML
{
function iconize(xml:XML):XML
{
if(xml.localName().indexOf("parent") != -1){
[EMAIL PROTECTED]"true";
}
var n:int=0;
var c:XML;
while(n < xml.children().length()){
c=xml.children()[n];
iconize(c);
n++;
}
return xml;
}
return iconize(xmlobj); 
}

Re: [flexcoders] Re: Accessing the illusive stage Object through sprite (a near impossible feat)

[Michael Schmalle]

Hi,

You could add a listener to that sprite from the inside or outside. Don't
know about the timing if it might already have passed from the out side.

The reason the stage object cannot be defined in the constructor is the
parent stage has not added it yet. :) That is where you get the event and
the stage is saying ok constructed object, your my child now, I will let you
know you have been added. Up until this point, the Sprite may have been
constructed but it still doesn't know about the stage which will eventually
be it's parent.

Peace, Mike

Re: [flexcoders] TabNavigator/ToggleButtonBar Style conflict

[Michael Schmalle]

Hi,

The reason it doesn't work is because TypeSelectors order in inheritance.

Tab {
   cornerRadius: 20;
}

Solves your Problem. This is not a bug.

Since you are setting a firstButtonStyleName on an actual selector,
TabNavigator will not pick it up since it is undefined to begin with and now
defined on the super class TypeSelector of TabBar.

If you set

.mytoggleButtonBarFirstButtonStyle {color: #FF;cornerRadius: 0;}

You will see that changes the radius of the first tab button.

Peace, Mike

On 5/31/07, Derek Vadneau <[EMAIL PROTECTED]> wrote:


  Code follows...

Setting styles for ToggleButtonBar overrides styles set for buttons of
TabNavigator.

The TabNavigator uses the ToggleButtonBar (actually, TabBar, which
extends ToggleButtonBar) for the "tabs".

What happens is if I set styles for the TabNavigator tabs, they are
ignored if I also set styles for the ToggleButtonBar.

Here is the code:


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

TabNavigator {
cornerRadius: 0;
tabStyleName: "myTabButtonStyle";
firstTabStyleName: "myTabFirstButtonStyle";
lastTabStyleName: "myTabLastButtonStyle";
selectedTabTextStyleName: "myTabSelectedButtonStyle";
}
.myTabButtonStyle {cornerRadius: 20;}
.myTabFirstButtonStyle {cornerRadius: 20;}
.myTabLastButtonStyle {cornerRadius: 20;}
.myTabSelectedButtonStyle {cornerRadius: 20;}

ToggleButtonBar {
buttonStyleName: "mytoggleButtonBarButtonStyle";
firstButtonStyleName: "mytoggleButtonBarFirstButtonStyle";
lastButtonStyleName: "mytoggleButtonBarLastButtonStyle";
selectedButtonTextStyleName: "mytoggleButtonBarSelectedButtonStyle";
}
.mytoggleButtonBarButtonStyle {color: #FF;}
.mytoggleButtonBarFirstButtonStyle {color: #FF;}
.mytoggleButtonBarLastButtonStyle {color: #FF;}
.mytoggleButtonBarSelectedButtonStyle {color: #FF;}

















All I'm trying to do is set the cornerRadius of the tabs to be some
value - I've exagerrated the value here and left out style properties
for the ToggleButtonBar buttons just so it's obvious what's going on.

The outside TabNavigator only has one tab and that takes on the style
of the TabNavigator selectedTab style. The inner TabNavigator shows
that the first and last buttons take on the ToggleButtonBar styles but
the middle button takes on the TabNavigator style.

If you comment out the ToggleButtonBar styles the TabNavigator styles
are applied properly.

As a workaround I can specify the styleName of the ToggleButtonBar I'm
using so that the style is specific to that instance rather than
global to all components.

I would classify this as a bug, unless someone can convince me why
this is expected behaviour.

[flexcoders] Re: create new button with an icon

[mazarflex]

i finally figured it out i put the buttons in a hbox and used the 
hbox.xhilddescriptors array with a loop. once the visibility is set 
it moves them into another hbox to keep the buttons side by side. i 
am not sure how to paste the code in here where it is still aligned, 
sorrry.

public function Loop():void{
var ArCtr:int
var ArMax:int = 
Holding.childDescriptors.length
do{
callCF
(499,'toolbar',Holding.childDescriptors[ArCtr].id)
ArCtr++
//Alert.show(cmdID)

Re: [flexcoders] Accessing the illusive stage Object through sprite (a near impossible feat)

Hi,

The stage object does not get defined until right at the end of the players
init cycle.

Try listening to the Sprites Event.ADDED_TO_STAGE event, then access the
stage object.

RE: [flexcoders] btn.width wont accept %

Width is of type Number.  Through MXML black magic we detect the % and
assign to percentWidth instead.

 

So, newBtn.percentWidth = 100;

[flexcoders] Re: Empty branch in a TREE - show folder instead of file icon?

[discipl4]

Richard,

Thanks for the response.  I want my leafnodes to keep the file icon,
although I will save your code snippet for the future because that
might come in handy :)

I really want my empty branch node to be treated as a branch.  But if
you have an empty branch, apparently it shows up like a leaf.  I want
it to look like an empty folder, with the triangle next to it for
expanding but with nothing underneath it.  

If I tack isBranch="true" onto each branch node, it works.  I just
dont want to have to manipulate the xml file if theres a way to do it
on the tree.

Thanks!

RE: [flexcoders] Re: Web Service Problems

1. You need fds.swc from LCDS 2.5. I'll send you details offlist (it's
due out publically very very soon). 
 
Actually, are you using the flex webtier compiler on tomcat to also
compile or are you using flex builder? If you're using the webtier
compiler you could just get the new flex.war from LCDS 2.5 as it has
been updated with hotfix 2 too.
 
2. I'll help you offlist with this as I'll need some more details from
you.

1) I updated flex builder 2.0.1 to hotfix 2. Since I am running my

relevant files I found in updated Flex SDK 2. After this I can't even
compile my app I get an error. Not sure if i am doing this right?
Error is the following /

2) If I don't update my tomcat WEB-INF/flex.
I removed format="xml" from my request so it doesn't binding issues.
and I carefully looked at my WSDL, so my parameters have the same name
as the part(WSDL is inluded above just in case).
My send() function returns me null object, so when I debug I cannot
see the SOAP body, cuz message=null. So eventually I get an error from 
fault-faultString = Required parameter 'orderId' not found in input

I believe the displaying of the tooltip causes the itemEditor to lose
focus which fires an itemEditEnd event.. thus destroying your
itemEditor.  I had tried something similar in the past and could not get
it working so had to take a different approach.

 

If you find a solution, please repost to the list.

[flexcoders] TabNavigator/ToggleButtonBar Style conflict

[Derek Vadneau]

Code follows...

Setting styles for ToggleButtonBar overrides styles set for buttons of
TabNavigator.

The TabNavigator uses the ToggleButtonBar (actually, TabBar, which
extends ToggleButtonBar) for the "tabs".

What happens is if I set styles for the TabNavigator tabs, they are
ignored if I also set styles for the ToggleButtonBar.

Here is the code:


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

TabNavigator {
   cornerRadius: 0;
   tabStyleName: "myTabButtonStyle";
   firstTabStyleName: "myTabFirstButtonStyle";
   lastTabStyleName: "myTabLastButtonStyle";
   selectedTabTextStyleName: "myTabSelectedButtonStyle";
}
.myTabButtonStyle {cornerRadius: 20;}
.myTabFirstButtonStyle {cornerRadius: 20;}
.myTabLastButtonStyle {cornerRadius: 20;}
.myTabSelectedButtonStyle {cornerRadius: 20;}

ToggleButtonBar {
   buttonStyleName: "mytoggleButtonBarButtonStyle";
   firstButtonStyleName: "mytoggleButtonBarFirstButtonStyle";
   lastButtonStyleName: "mytoggleButtonBarLastButtonStyle";
   selectedButtonTextStyleName: "mytoggleButtonBarSelectedButtonStyle";
}
.mytoggleButtonBarButtonStyle {color: #FF;}
.mytoggleButtonBarFirstButtonStyle {color: #FF;}
.mytoggleButtonBarLastButtonStyle {color: #FF;}
.mytoggleButtonBarSelectedButtonStyle {color: #FF;}

















All I'm trying to do is set the cornerRadius of the tabs to be some
value - I've exagerrated the value here and left out style properties
for the ToggleButtonBar buttons just so it's obvious what's going on.

The outside TabNavigator only has one tab and that takes on the style
of the TabNavigator selectedTab style. The inner TabNavigator shows
that the first and last buttons take on the ToggleButtonBar styles but
the middle button takes on the TabNavigator style.

If you comment out the ToggleButtonBar styles the TabNavigator styles
are applied properly.

As a workaround I can specify the styleName of the ToggleButtonBar I'm
using so that the style is specific to that instance rather than
global to all components.

I would classify this as a bug, unless someone can convince me why
this is expected behaviour.

[flexcoders] Accessing the illusive stage Object through sprite (a near impossible feat)

[patricklemiuex]

Dear Actionscript wizards:

I have an all as3.0 project.

I can never seem to access the stage object (I've posted several times
and never can get any appropriate solutions)?  i thought this was
automatic with every class that extends sprite... I get a null object
reference trying to access the stage object.  I must be doing
something incorrectly, though I have studied this in a few places.


public class AbstractSlideView extends Sprite 
{
protected var _data:PictureProviderXML;
//protected var _data:PictureProvider;
private var _paramObj:Object;

public function AbstractSlideView() {
var timer:Timer = new Timer(1000,1);
timer.addEventListener(TimerEvent.TIMER, installVars);
timer.start();
this.stage.focus = this;
this.addEventListener(KeyboardEvent.KEY_DOWN,keyHandler);
this.addEventListener(KeyboardEvent.KEY_UP,keyHandler);
}

[flexcoders] Re: coldfusion wizard

[David]

Sounds like a path problem. Make sure you check your syntax for each
component to see if the root folder is first. IE - if you have a
website path of mysite/flexapp/etc and your components are in the
flexapp, they won't be found. Make sure your components say
mysite.flexapp.component . 
Hope this helps,
David

[flexcoders] Dynamic Icon for Button

[Matt]

Is there any way to dynamically load a "icon" for a Button at runtime
instead of embedding it?  If not, is there any third-party components
that add support for this or am I left to do this for myself?

[flexcoders] Re: Empty branch in a TREE - show folder instead of file icon?

[discipl4]

Sorry - I forgot to state... this xml is coming from a webservice ..
so .. I cant just change my XML to say isBranch=true :):)  Unless the
solution is to append that attribute onto each node programatically.

[flexcoders] CSS Gurus: Different StyleManagers within one Application???

[Aldo Bucchi]

Hi all,

I have two different applications ( swfs ) that are loaded at runtime
using two SWFLoaders inside a third application ( that acts mainly as
a shell ).
I need their CSS styles, skinning, etc to be independent... but the
behaviour I get is that their styles get merged ( first one loaded
wins ).

Is it possible to achieve this separation??

What I am doing is something similar to the Flex Style Explorer, but
the controls used to tweak styles at runtime have to be stylable using
an independent, inmutable CSS file... their styling MUST NOT be
affected by any runtime modifications.

I cannot create specific class selectors for these controls, because
the CSS file already exists and makes use of type selectors as well.

One obvious solution is to make two completely separate applications
and have them talk through a LocalConnection. But this leads to some
unwanted layout problems in my specific case ( ColorPickers on the
controls application won't be able to hover over the other app, thus
not leaving them enough real estate to display correctly ).

Thanks,
Aldo

RE: [flexcoders] Array errors

[Tracy Spratt]

This error occurs because of the way the Flex compiler converts the mxml
into an as class before compiling the swf.  homeNav does not yet exist
when you make the assignment in the second line.

 

The fix is to do all posible initialization in a function, rather than
in the "root" of the script block.  Call that init function using the
creationComplete event.


public var homeNav:Array; 

Private function initApp():void {

  homeNav = new Array();

  homeNav[0] = "12";


 

This would probably work as well:

public var homeNav:Array = ["12"];

 

But it is a good habit to do most of the work in a function.

You do this the same way you would with a Flash application. You can use

RE: [flexcoders] Re: Tooltip in itemeditor of datagrid BUG or... WIsh...

I believe the displaying of the tooltip causes the itemEditor to lose

it working so had to take a different approach.
 
If you find a solution, please repost to the list.

OK -- I'll see where I might be able to redirect this.

While I'm fully aware of security restrictions -- I didn't expect to run

"works", it just seems so unnecessary.

Thanks for the input!

  Essentially, the problem boils down to this:

"If you want to connect to a socket on a different host than the one
from which the connecting SWF file was served, or if you want to
connect to a port lower than 1024 on any host, you must obtain an
xmlsocket: policy file from the host to which you are connecting."
---http://livedocs.adobe.com/flex/2/langref/flash/net/Socket.html#connect

Why do I need to implement an XMLSocket server, to open a Socket to a
service on my server that isn't an XMLSocket service? Why can't it get
the information it needs from an HTTP resource?

"A policy file obtained from an HTTP server implicitly authorizes
socket access to all ports 1024 and above; any to-ports attributes in
an HTTP policy file are ignored."
---
http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=1952.html#145389

It seems as though the intent is to prevent the Flash player from
communicating, using Sockets, to any standard HTTP server setup (port
80 open, nothing else). Why?

[flexcoders] Re: DataGrid HeaderRenderer Recreates every click

[e_baggg]

Alex-
  Thanks. The issue is when a user clicks a column header, all the
column headers are re-created and now there is no way to know what
just happened since any state of that click event is lost. So I guess
I am forced to save it outside the headerRenderer. 

I suppose I can store the column index of what was clicked, then each
column when it redraws itself can get that int (if it's not -1), look
that value up in the 'columns' array and see if itself is it. If so,
then display the appropriate up/down arrow.

The DG default code assumes that you are pulling properties for display
and stuffing them on edit.  Your label functions are not simply property
pullers so you'll need to customize an ITEM_EDIT_END handler, call
preventDefault() and stuff it yourself.

Is it just me, or is it a bit surprising that we've got to hack

enough asynchronous problems to deal with than have to worry that the

cursor is being shown. I understand that some folks may not want it to
*always* prevent mouse clicks, but a little boolean flag (or two) in the

How many components are we talking about?

Generate an Alert and position it outside the viewable area. They're
modal by default... meaning the user shouldn't be able to click on
anything till you clear it.

RE: [flexcoders] TabNavigator selectedIndex property

[Alex Harui]

Might be timing.  Try setting selectedIndex either before or after
adding children or maybe later via callLater

Subject: [flexcoders] TabNavigator selectedIndex property

 

Hey all,

I've run into a problem when trying to set the selectedIndex property
on a TabNavigator. The TabNavigator is set in mxml, however I am
adding and removing children with AS3 at runtime depending on what
node the user clicks in a Tree control (hope that makes sense). The
children are doing what they are supposed to (i.e. attaching and
removing, and getting initialised with whatever data I pass to them).
But when the selectedIndex is, say, 3 and then the user clicks a tree
node forcing the TabNavigator to remove and reload children, I am
trying to reset the selectedIndex property back to 0 (to show the
first tab) - this part works, that tabnavigator shows the right tab,
but the tab button that appears selected is still the old property (3
in this scenario). 

So is this a display problem or the way that I am adding/removing
children? I have tried invalidateDisplayList() and callLater, but
nothing seems to help. Hope someone has some insight...

Cheers.

 

RE: [flexcoders] LoadModule, creating a history so the Back Button works...

[Alex Harui]

Not sure I understand.  If you put ModuleLoaders as children of a
TabNavigator and enable History in the HTML wrapper, it should just
work.

How would I do this?
Currently I have a TabNavigator, and when I click on tabs, it creates 
something that enables a browser history, how do I use whatever its 
doing to create my own history item? 

basically in the tabnavigator I have buttons that load a module, it 
would be nice to enable the back button to load the previous module.

any ideas? Thanks in Advance

Ideally what I would like to do is to controls label and ticks to
display for example only the label of the first business day of each

RE: [flexcoders] DataGrid HeaderRenderer Recreates every click

[Alex Harui]

People do some really tricky things in customized DGs like having
headers grow and shrink or other rows grow and shrink based on rollover
states and selection and what not.  Right now the DG aggressively
redraws to make sure we don't make assumptions about what can change.

 

In theory, your custom header renderers should derive their state from
some description of the sort.  That's a good model/view design and the
cost should be insignificant.  Maybe the way you're checking is
non-optimal.

Subject: [flexcoders] DataGrid HeaderRenderer Recreates every click

 

I have a server-side sort on my DataGrid which means I had to
implement my own headerRenderer to handle the click event, sort, and
server calls. 

I am trying to create the asc/desc arrow now but I realized that any
click event on the DataGrid instantiates a new Object of the
headerRenderer (all of them actually). In other words, my
headerRenderer mxml implementation, the creationComplete event gets
called any time ANYTHING is clicked in the grid, including a row.

This is a problem for many reasons, but the most significant one being
that I cannot store the state if the column is ascending/descending
based on the user's click. I could store this externally in the model
but that is very bad b/c then I'd also have to store which column was
clicked and then the other columns have to check if it is itself and
remove the arrow if they have one. Does anyone know why the
headerRenderer is re-creating an instance of itself every time or
faced this issue?

Thanks in advance.

RE: [flexcoders] BarChart - Reversing draw order?

[Ely Greenfield]

 

 

 

Nope. The all charts try to render axes consistently The 'first item' in
a category axis corresponds to zero. A horizontal axis always puts zero
on the left, and a vertical axis always  puts zero (or the lowest value)
on the bottom.  So the first item in the axis goes on the left on the
horizontal, bottom on the vertical.

 

If you wanted to change that, I'd suggest either trying to extend the
Category Axis to reverse the order in which it reports categories, or
write your own.

 

But the easiest way to do it would be to provide a separate dataProvider
to your categoryAxis that has the same values, but sorted in reverse
order. Then make sure you assign an xField to your series (if you don't
provide an xField, it just maps the items to the categories by index,
which would not work. Instead, you want to match the items to the
categories by value, which would place them in the correct spot along
your inverted category axis).

 

Ely.

Yes, or add another class layer between, or make the method replaceable,
or make the method in A callable directly, or add a flag

 

Adding another class layer is the purest form, but adds the weight of
another class

Extending from A might cause too much duplication of code from B

 

Replaceable methods and other tricks are kind of cheating but do work

 

Class A

{

// subclasses replace the actual function they need called

Protected var _myFunc:Function = myFuncA;

 

Protected function myFunc(a:Object, b:Object):int

{

return _myFunc(a, b);

}

 

Protected var myFuncA(a:Object, b:Object):int

{

// A's default behavior

}

}

Is it just me, or is it a bit surprising that we've got to hack something

problems to deal with than have to worry that the user's going to go off
willy-nilly clicking buttons while the busy cursor is being shown. I
understand that some folks may not want it to *always* prevent mouse clicks,
but a little boolean flag (or two) in the CursorManager that prevents mouse
clicks and/or focus changes/keyboard events would be very, very nice.

Generate an Alert and position it outside the viewable area. They're modal

Re: [flexcoders] Re: CheckBox check icon style - checkColor hardcoded?

[Derek Vadneau]

An update on this. I missed the style for the disabled colour, so the code
modification should be:

   /*
   Modified by {your name} (05/31/2007):

   The iconColor variable now gets its value from getStyle if it can,
otherwise it defaults to what was hardcoded in the CheckBoxIcon.as file.
   */
   var defaultIconColor:uint = 0x2B333C;
   var defaultIconDisabledColor:uint = 0x99;

   var iconColor:uint = defaultIconColor;
   if (getStyle('iconColor') != undefined) iconColor =
getStyle('iconColor');

   var iconDisabledColor:uint = defaultIconDisabledColor;
   if (getStyle('iconDisabledColor') != undefined) iconDisabledColor =
getStyle('iconDisabledColor');
   /*
   End modification.
   */

And down further in the code in the case "selectedDisabledIcon" section
(line 375 in the original CheckBoxIcon.as file), change:
checkColor = 0x99;

to:
iconColor = iconDisabledColor;

Also, make sure to change checkColor to iconColor (line 402 in the original
CheckBoxIcon.as file).


Alex Harui,

Will the disabled version be iconDisabledColor or disabledIconColor?
Personally, I prefer when styles are grouped in context, as in iconColor,
iconDisabledColor, iconOver, iconDisabled. Makes it easier to find styles in
the context of what you are modifying, instead of looking for states that
are related to the context, as in disabledIconColor, overIcon, disabledIcon,
etc. Two different ways to look at it, I guess.
