In my custom button component, I want to get a handle on the textField (The internal UITextField object that renders the label) in the Button so I can modify some properties on it. It exists as a protected var in Button.as How can I do that in my mxml component?
View 1 RepliesI'm trying to extend a class like panel so that I can fire click events only when the title area is clicked on. The title area is a protected uicomponent of Panel called titleBar. So I want to make that component public.It seems like I'm almost there but I'm getting a "TypeError: Error #1009: Cannot access a property or method of a null object reference." when it tries to add an event listener to the titlebar.
here is my extended panel
package custClass{
import mx.containers.Panel;
import mx.core.UIComponent;
public class ExtPanel extends Panel{
[code]....
And then this in the AS:
newPanel.getTitleBar().addEventListener(MouseEvent.ROLL_OVER,over);
Still getting the same error.
Assign an event listener to a protected timer variable in the parent class.
I am working with Adobe LCCS, and created a BatonProperty which implements Baton
Now, Baton has a protected timer variable declared like this, and for some reason, I am unable to get access to this _autoPutDownTimer, from a BatonProperty instance.[code]...
Is it possible to have a property with a public getter and protected setter? I have the following code:
public class Mob extends Sprite {
// snip
private var _health:Number; // tried making this protected, didn't work
public function get health():Number { return _health; }
protected function set health(value:Number):void {
[Code]...
I did have this.health -= dmg; but I split it out to get more details on the compiler errors. I don't understand how the property would be considered read-only within the same class. I also don't understand how it's inaccessible. If I make the backing field, getter, and setter all protected, it compiles but it's not the result I want; I need health to be readable externally.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
I keep getting this error :1150 The protected attribute can only be used on class property definitions.
panel1.addEventListener(MouseEvent.CLICK, onClickPanel);
panel2.addEventListener(MouseEvent.CLICK, onClickPanel);
panel3.addEventListener(MouseEvent.CLICK, onClickPanel);
panel4.addEventListener(MouseEvent.CLICK, onClickPanel);

Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.
View 2 RepliesI would like to bind a variable from my ActionScript to a property of a component that is in a ItemRender. But I always get this error:

I have a custom Flex 4+ component that I am trying to make and have the skin be aware of changes to a custom property. This property will determine the graphic on the button (and some other visual changes) but the data will change constantly as it will be updated by a timer.
I've looked at untold examples and still seem unable to get the syntax correct or discover how things should be separated. I've looked at overriding commitProperties and the PropertyChangeEvent without success. So I have two questions.
1) How can I get a skin to be notified of a bound property when it changes?
2) If the data for a bound property of the component is an object, will binding work properly if a property of the object changes (or would it be better to pass each property separately)?

I would like to know if it is the same to assign properties to my custom component in its own class, or from the parent document. Here I assign the property bottom in my custom component class:
<?xml version="1.0"?>

<mx:Script>
Here I assign the property bottom when I use the component in my main MXML file
<myComp:Brick bottom="10"/>

In Flex I've got a component, which is based on a Canvas.It looks like this (I removed the <mx:Script> for better reading):
<mx:Canvas verticalScrollPolicy="off" showEffect="showFX" hideEffect="hideFX" horizontalScrollPolicy="off" creationComplete="doComplete()" xmlns:mx="http://www.adobe.com/2006/mxml" width="63" height="63">[code]....
If I set customComponent.Visible to false, the component gets hidden (as expected). But doesn't trigger the hideFX at all. Am I doing something wrong? Or isn't this the correct way to use hideEffect and showEffect?
how do i get an ordered list using htmltext property of Text component? I tried using this: <ol><li>item</li><li>item</li></ol> but it rendered like an unordered list.
View 2 RepliesI'd like to use a button within a component to remove it. So, you click it and the component is gone. But, I haven't figured out how you reference the component from within the component. What should I put in click=""?

I want to create a custom button in ActionScript. [code]...
View 2 Repliessince i started using Flash Builder (Flex 4) i could see that it can auto-generate some handlers for example if i have a <s:Button> and i add a click="" i get a hint of "Generate Click Handler" and when i click Enter he writes this code:
Code:
protected function button1_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
}
Now i knew about public and private things(functions/vars) and if a function was public i could execute it form outside of the class and inside. But if it was private i could only execute it from inside of the class and i couldn't execute it from outside of the class.
So anyway, what does "protected" mean? what does it do?I was thinking that if i load a SWF in my app I can go inside of that SWF and execute functions, read values from variables, or anything like that ... and that seems like a security problem ... So i was wondering if the "protected" keyword could help me with this security problem. And if not, I would like to know what is it good for
I'm generating buttons dynamically that I want it to call a method like this:

buttonVGroup.addElement(button);

I installed Eclipse with Flex plugin. And I found in my current workspace, IntelliSense can only show the public methods, it cannot show me the protected methods (but it can compile and the app runs well).However, in other workspaces, it works well.If I create a new workspace, it's the same, that the IntelliSense can only show me the public methods, not protected methods.
View 1 RepliesI am building a Flex application with ActionScript 3. Unfortunately I've hit a wall with this one...I would like to be able to apply an upSkin to my dynamically generated button like this:
//this theSkin variable is dynamic in my app, but for this example it's a simple string
var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif";
var navBtn:Button = new Button();
navBtn.id = "thumb1";
[code]....
When I attempt this, I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class.
How do I skin this button with my image dynamically? A couple of things to consider:The upSkin image must be remote. It can't be local.The button must be generated dynamically (it's in a for loop).
I want my custom button to look like the button sample below. More specifically, I want the width of the button to be determined by the width of the largest word in the label (i.e. width of "Elongated" in my example). The label must wrap, not truncate. And I want only one pixel between the top edge of the icon and my button's top edge. I have tried lots of things but to no avail so far. I have reduced the horizontalGap and verticalGap to zero and padding to zero. But still nothing.

Just wondering How I would place the Flex button component on the stage with actionscript and make it execute a function when pressed...this is easy in MXML:
PHP Code:
<mx:Button label="Button" click="function();"/>
but I need to do it with actionscript..
I am trying to create a custom component in flex that consists of a Button, and a TileList directly below that button. On button click event the TileList should open/close. The component works fine, but when I add it to my main flex app, inside a VBox, it simply opens and closes within the VBox. Because the height of the VBox is much smaller than the custom component's TileList, it causes scrollbars. My issue with it is that it should behave like a ComboBox/Pull-down menu and go over the VBox, instead of going inside it. how to overlay the custom component, so it behaves like a ComboBox/Pull-down?
View 1 RepliesIt is possible to bold some part of label in standard Button? example:ICON - normal_normal_text BOLD_BOLD_text.
View 2 RepliesIn Flex, lets say I have a super-class... something like:
class SuperComponent extends DragStack {
private var _childReference:UIComponent;
public function SuperComponent() {
// ???
addEventListener(FlexEvent.CREATION_COMPLETE, onCreationComplete);
} private function onCreationComplete(e:FlexEvent):void {
//The 'this[]' technique doesn't seem to work and causes run-time errors:
//trace("Component found: " + this["myButton"]);
}}
And then I make use of the following derived-class in my application (just a mockup MXML as an example):
<!-- Component ChildComponent.mxml -->
<mx:SuperComponent>
<mx:Button id="myButton" label="Press Me!" />
</mx:SuperComponent>
How do I go about verifying the presence of "myButton" from the SuperComponent class, and referencing it? Do I need to use getChildByName( ... ) ?
I'm having issues with implementing a flex button componentI have applied a CSS style to button and set border-color to, say #555555.So far, it works as expected.Then, when my application is resized, the border of the button component becomes blurred and its width automatically changes from 1 pixel to 2 pixels, which doesn't look very well.hen I maximize the app again, after the border is blurred, the buttons' border becomes 1 pixel and looks nice.
