Re: [flexcoders] Using an Alert when handling another event?
You need to use preventDefault() in the confirmTabDelete function and then
display the Alert box. Then when the user clicks ok, close the tab
programmatically. I'm not familiar with SuperTabNavigator but normally this
kind of events are only dispatched as a result of a user action, so when you
close the tab programmatically the second time, this will really close it
without going through the event handler.
private function confirmTabDelete( event:SuperTabEv ent):void {
Alert.show(" Are you sure you want to delete this tab?", "Confirm
delete", Alert.YES | Alert.NO, this, alertListener, null, Alert.NO);
event.preventDefault(); // Prevent default here
}
private function alertListener( eventObj: CloseEvent) :void {
if (eventObj.detail= =Alert.NO) {
closeTab(); // Really close the tab here
}
}

I'm using a SuperTabNavigator control from the flexlib package.
When
the user clicks on the close button for a tab it fires the tabClose
event. I have specified a handler for this in the mxml for the
SuperTabNavigator component:
tabClose="confirmTa bDelete(event) ;"
In the confirmTabDelete function I would like to pop up an Alert with
YES | NO buttons. According to the SuperTabNavigator docs I can
cancel the delete action by calling event.preventDefaul t() within the
confirmTabDelete function. My problem is that the Alert box uses its
own handler function for the YES/NO button clicks. I'm not sure how
that handler function can reference the event object to call
preventDefault( ).
private function confirmTabDelete( event:SuperTabEv ent):void {
Alert.show(" Are you sure you want to delete this tab?", "Confirm
delete", Alert.YES | Alert.NO, this, alertListener, null, Alert.NO);
}
private function alertListener( eventObj: CloseEvent) :void {
if (eventObj.detail= =Alert.NO) {
//Now what? How to call preventDefault( ) on the event object
in confirmTabDelete?
}
}
Is the secret in the "this" which is being used as the parent for the
Alert?
Any help would be great.

Re: [flexcoders] Re: Flex server language
Although I prefer open source software, it's true that most of the time it's harder to use an open source version that a "paid for" equivalent. Coldfusion is easier to setup than PHP, Photoshop or Word are more user friendly than Gimp or OpenOffice and so on. Open source software is free but you're kind of expected to make more efforts to use it - i.e. read the doc, search Google. Once you are used to it though, it's just as good as the paid equivalents. -- Laurent Cozic Flash, Flex and Web Application development http://pogopixels.com --- On Fri, 2/20/09, Jeffry Houser wrote: From: Jeffry Houser Subject: Re: [flexcoders] Re: Flex server language To: flexcoders@yahoogroups.com Date: Friday, February 20, 2009, 4:29 PM It's easy to get things done / setup if you already know what you're doing.

Re: [flexcoders] Drawing on skinned component
> I have tried using a Sprite as the topmost child and drawing on it
I think that's the way to do it. To make sure that your sprite is always on
top, just add "addChild(yourSprite)" at the end of the updateDisplayList
function. If the sprite is not on the display list, it's going to be added to
it, and if it's already there, it's going to be pushed on top of all the other
sprites.

Hello,
I'm trying to draw something on a component skinned using a Flash
skin, but nothing is drawn (or better said, I don't see anything
because the drawing is done beneath the skin).
My code looks something like
public class TestButton extends Button
{
public function TestButton()
{
super();
}
override protected function updateDisplayList( w:Number, h:Number):void
{
super.updateDisplay List(w, h);
var g:Graphics = graphics;
g.moveTo(0, unscaledHeight / 2);
g.lineStyle( 1, 0x00);
g.lineTo(unscaledWi dth, unscaledHeight / 2);
}
}
I have tried using a Sprite as the topmost child and drawing on it,
but apparently there's always something above my Sprite and I still
can't see what I draw.
I've googled and searched the group archives for a similar problem,
but either I'm not using the right search terms or nobody had such a
problem before because I can't seem to find anything of help.
So, does anybody have some pointers as to what might one do to draw on
such a component?
Thank you!

Re: [flexcoders] Re: is it possible to track visitors / the page an swf is embedded on
Application.application.url will give you the url of the *swf file*, not the
url of the document within which the app is embedded. For that, the only way is
to use Javascript and ExternalInterface. I think the syntax is:
var docURL = ExternalInterface.call("location.href");
or it might be "document.location.href" - not sure which one is right.

RE: [flexcoders] Displaying custom items in ComboBox
The exact order of events is described in "Creating and extending Flex
components" of the help file. However, in general you shouldn't expect the
update handlers to be called in any particular order, since a subclass could
force a call to updateDisplayList() or measure() without your objects being
ready. So basically you should always check if an object exists before trying
to access it.
Also, if I'm not mistaken, createChildren() might be called more than once
during the life time of a component (I think that's when it's removed from the
stage and added back), so you also need to check that "lineHolder" is not null
before creating it.

updateDisplayList just as you have. I’m a C/C++ developer new to
Adobe Flex and am trying to grasp everything. I guess I’m not fully
understanding the call stack on this and the order of methods it calls to
render the dropdown. Is there a good place to learn this? I had to
put a check in place inside of updateDisplayList to check for null because the
function was being call initially, even before the combobox was rendered.
I figure I’m just missing the whole picture which is why I’m not
understanding where the selected label is being set. Thanks.

Hi, you need to stop the event propagation so that it doesn't reach the canvas.
You do that in your button event handler:

trace("trace button " + evt.target + "/" +

Hi,
A simple question :
I have a simple Flex application, which has a canvas and a button
nested within this canvas.
Both, the canvas and the button have an event handler bound to the
"click" event.
When I click the button, both the event handlers of the button and the
canvas are called... I expected
only the event handler bound to button to be called, as this is the
"deepest nested node"..
The Adobe documentation says the following about MouseEvents :
"When nested nodes are involved, mouse events target the deepest
possible nested node that is visible in the display list. This node is
called the target node."
http://livedocs. adobe.com/ flex/201/ langref/flash/ events/MouseEven t.html
How can I accomplish only the event handler of the button to be called ?
Thanks for your help !

Re: [flexcoders] Class file in flex
You can't include a class within a class, you can only include "plain" ActionScript files. So to fix your issue, you simply need to remove the "package" and "class" statements from your actionscript file. You should probably also remove the "import Inculdes.ClassTesting;". Also it might compile, it won't make any sense once you convert the AS file. -- Laurent Cozic Flash, Flex and Web Application development http://pogopixels.com --- On Tue, 8/12/08, litesh_b321 <[EMAIL PROTECTED]> wrote: From: litesh_b321 <[EMAIL PROTECTED]> Subject: [flexcoders] Class file in flex To: flexcoders@yahoogroups.com Date: Tuesday, August 12, 2008, 10:59 AM hi guys, I am trying action script class in flex 3.0 I have action script class in "Inculdes\ClassTest ing.as" directory which is situated inside src directory.

Re: [flexcoders] Loop through all visual components
Somebody ask a similar question on this list recently. You can loop through all
the components in your app by using the numChildren property and getChildAt
method:
function checkAllButtons(container) {
for (var i = 0; i < container.numChildren; i++) {
var c = container.getChildAt(i);
if (c is Container) {
checkAllButtons(c);
} else {
if (c is Button) {
// Do your changes here
}
}
}
Then start the process by passing the application as a parameter:
checkAllButtons(Application.application);

Re: [flexcoders] Returning value inside a nested functions event?
By definition an event handler shouldn't return a value, since no object can
actually retrieve this value. You'll need to use some other way - perhaps you
could save the result in a private variable inside you class, or have the event
handler call another method. It depends on what you are trying to do.

Re: [flexcoders] Re: TextArea - Limit the amount of text
Yes that's right, that wouldn't work in that case. Then one solution would be
to save the text property when you know it's below the limit (for example in
the TextInput event), then in the CHANGE event, check the text height again. If
it's above the limit, restore the previous text property. You might also want
to save and restore the caret position as well (see selectionStartIndex and
selectionEndIndex)

the issue is this

c
is a certain textHeight, whether the cursor is on the a or the c, so
if they hit that textHeight, then no matter whree they put the cursor,
the textHeight is at the limit, so i prevent the default.
if I delete the c, the textHeight is no longer at its limit, so I can
edit anywhere I want.

Re: [flexcoders] TextArea - Limit the amount of text
You could do it by listening to the textInput event. When it's triggered, check
if the text height is above a certain limit (for example the TextArea height -
font height): if it is, cancel the event.
The code below should work:
textArea.addEventListener(TextEvent.TEXT_INPUT, textArea_textInput);
protected function textArea_textInput(event:TextEvent) {
if (textArea.textHeight > textArea.height - textArea.getStyle("fontSize")) {
event.preventDefault();
}

If so, that's an odd limitation, but sounds faesible since this bug isn't making any sense to me anyway.
Re: [flexcoders] Re: problem adding images to UIComponents using AS3
I didn't read the other replies, but in general I think it's not a good idea to
add a Flex component to a non-Flex object. You might be able to get it to work
by simulating the framework workflow - for example, by manually calling all the
"invalidateXX" methods, however it's not a very clean approach.
In this case, a better way would be to directly create an instance of your
embedded object and add it to the display list. I think the syntax would be:
var image:BitmapAsset = new _moveGroupImage() as BitmapAsset ;
this.addChild(image);

Subject: [flexcoders] Re: problem adding images to UIComponents using AS3
OK, let me back up here. First, thanks to those who responded. So I thought
by isolating my problem with an example (heck, I'm not even using Canvas) it
would shed light on why this bug is occuring, but it isn't unfortunately, I'm
more or less confusing the real problem with y'all. Sorry. So maybe what I
thought was the problem was instead something else.
Here is my actual project code, and a description of the setup. The problem
is, the image is not getting attached to the sprite, even though the sprite is
showing up in the display list just fine (the graphics draw from code - but the
image doesn't show). I know the path to the image is right, I can use the same
embed and new Image() code elsewhere in my app to make the image appear. Here
is the code and the setup in the application:
package com.venice.view. network.grouping Tool
{
import flash.display. Sprite;
import mx.controls. Image;
public class GroupHandle extends Sprite
{
public var id:int;
public const FILL_COLOR:uint = 0xff;
public const FILL_ALPHA:Number = .5;
public const STROKE_COLOR: uint = 0x00;
public const STROKE_THICKNESS: Number = 1;
public const STROKE_ALPHA: Number = 1.0;
public const SIZE:Number = 10;
[Embed(source = "/media/icons/ control_repeat_ blue.png")]
[Bindable]
private var _moveGroupImage: Class;
public function GroupHandle( ):void
{
//this works:
graphics.clear( );
graphics.lineStyle( STROKE_THICKNESS , STROKE_COLOR,
STROKE_ALPHA) ;
graphics.beginFill( FILL_COLOR, FILL_ALPHA);
graphics.drawRect( -(SIZE/2) , -(SIZE/2), SIZE/2,
SIZE/2);
graphics.endFill( );
//this doesn't:
var icon:Image = new Image();
icon.source = _moveGroupImage;
addChild(icon) ;
}
}
}
This class, GroupHandle. as, which extends Sprite, is added in the display list
in my application as follows:
Application(main MXML) > network(Panel based MXML component) >groupsLayerUI
(a UIComponent, necessary because it's added to a Panel container)
>groupingTool(.as class that extends Sprite) >groupHandle(.as class that
extends Sprite)
The groupsLayerUI UIComponent seems to be fine holding other content, and even
in the groupHandle, it renders drawn graphics just fine. Just not the image.
Even if I size the UIComponent, it doesn't work. It's not making any sense to
me why this image doesn't appear in this sprite, even though it will appear in
other places in my app, and even though other graphics in the sprite appear
fine. I thought maybe it had something to do with also drawing on the same
sprite, but that's not it either, I removed that code and it still fails to
load the embedded image. Can someone figure out what could be wrong? Thanks.

Re: [flexcoders] Re: Fading out text
Actually it doesn't really matter what the defautl font is or if it's installed on the user's system or not. If you want to change the alpha, rotation or, in general, use any effect on a text component, you have to embed the font. This is actually a limitation of the Flash Player, not Flex, so there's not much we can do about it. If I'm not mistaken, this limitation will be gone in Flash 10 though. -- Laurent Cozic Flash, Flex and Web Application development http://pogopixels.com - Original Message From: cesarerocchi <[EMAIL PROTECTED]> To: flexcoders@yahoogroups.com Sent: Friday, August 1, 2008 3:50:42 PM Subject: [flexcoders] Re: Fading out text > You need to use an embedded font in order for the fade effect to work. Simply > create a new style for your text, then tick the "Embed this font" check box in the style properties. Thanks for the quick reply. A follow up question. What if I am ok with the default font (I work in Adobe Air) and I didn't embed any font in my application? Isn't that font, the default one, already embedded? If not, what's the name of the default font? Thanks, -c.

Hi, You need to use an embedded font in order for the fade effect to work.

If the format function is a custom function you have written, you could just have it check whether you like the result it is about to return, and if not, return something else. If that is not the case, I believe that you should be able to put tests into your binding statement. You could test for NaN with something like this: I'm not sure about infinity, but I assume that you can test for this by looking for the greatest possible value of the number. Assuming that you have set up the variable maxValue to contain that value, you should be able to do something like this: If you put the two together, it would look something like this: Sid Maskit Partner CraftySpace Better Websites for a Better World http://www.CraftySp ace.com blog: http://smaskit. blogspot. com/

Normally, the way to pass parameters to the item renderer is through its "data" property.

How did I get this and how do I fix it? I also get a security sandbox violation error on a flex project after checking out from SVN. I have a flex project that compiles and runs fine on the original development computer. I then check in my source code to an SVN repository. When a fellow developer checks the project out from SVN and tries to compile on their system, they encounter the security sandbox violation error. My flex application never tries to access a remote file. The security sandbox violation occurs while trying to access a local XML file in the project directory (source code in src/, swf in bin-debug/ and xml file in assets/ --- all three are sister directories) .

[flexcoders] Re: How do you identify a component created in a repeater????
Within which context? If you need to know which component has
triggered an event, you can use event.currentTarget, as in:
Then in a script block:
function clickHandler(event) {
var yourComponenet = event.currentTarget;
// From then you can also get this.parent.getChildAt(n)
// to get the other components
}
