Flex :: Access Component Properties From Extending Component
Jul 29, 2011
I have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

when extending a flex component and trying to use it, I get a RTE. I.e. I am extending a DataCanvas and am using it like this:
<MyComponent dataProvider="{dataProvider}" width="100%" height="100%" x="0" y="0" id="dc" verticalCenter="0" horizontalCenter="0" />
Has anyone seen this? How can I get around it?

I'm extending the Flex 3 panel component. I need to figure out the width of the title's text. Because, title is a private variable in panel, I can't access it via title.width.I know the font, fontsize (14), and length of the title (which will vary). Knowing this info is there a way to calculate how many pixels wide the title is?

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?

Let's say I have a defined ClassA. ClassB extends ClassA and there's a Movie Clip instance on the stage linked to ClassB. How would ClassC access the properties and methods of ClassB without extending ClassB or creating a new instance of ClassB? The way I'm currently doing it is by referencing the stage instance linked to ClassB and then using the dot syntax to access ClassB instance variables, and this works only if the the accessed variables are public or internal, depending on what package ClassC is part of. I would like to know if there's a better, cleaner way to accomplish this.

I found this sentence while googling out for Flash help: "Add 3 frames to your timeline. Drop a TextField on your Stage & make sure it extends over all the 3 frames." I was not able to accompolish the second task of this. I added the frames, dropped a TextField on the first frame, but could not find a way to extend it over all the 3 frames.

I'd like to adjust the width of the default ScrollBar that appears inside of a Flash ComboBox. From my research on various forums, it seems like the best approach would be to subclass fl.controls.ScrollBar, which I've tried doing here:
package helpers {
import fl.controls.ScrollBar;
public class CustomScroller extends fl.controls.ScrollBar {
[Code].....
Then, in my library, I've taken the "ScrollBar" movie clip that appears upon initial creation of a ComboBox and changed the base class to "helpers.CustomScroller". I've got three ComboBox instances on the stage; however, none of them are showing anything but the default width, nor am I seeing the output from the trace() statement in my constructor.

I've never extended a component class in AS2, and I'm having problems with it now.
Here's my class file:
Actionscript Code:
import mx.video.FLVPlayback;import mx.video.*;class AkamaiFLVPlayback extends FLVPlayback{
public function AkamaiFLVPlayback(){
super()}}
Here's how I'm trying to instantiate it from the FLA:
Actionscript Code:
import AkamaiFLVPlaybackvar g = new AkamaiFLVPlayback()this.attachMovie(g,myVid,1)g.contentPath = "[URL]"
Now this does not work at all. I can see that the super class FLVPlayback is creating variables, but it's not loading to the stage or initializing.

I have some generic functions like copy, paste,etc in an AS file. I want to use them for editing data present in different mxml applications embedded in one application. If I pass the child's component id as a parameter of a function in one of the events, I get the value as either null or the parent app name. But I want the id of the child's component to access the values.

I need to access topBox's grandchildren and determine whether they're buttons or not. This function belowgrabs topBox's immediate children which are the HBoxes. How do I go one level lower to topBox's grandchildren? Or is the only way to do this is to run this function on each HBox?
for (var i : int =0; i<topBox.numChildren; i++){
var child : DisplayObject = topBox.getChildAt(i);
var myButton:UIComponent = child as UIComponent;

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

This is the setup. I have created a timeline with a playhead. When my playhead is dragged I would like the timeline to scroll with the drag.
So far, the only way I can do this is by setting clipAndEnableScrolling to true. But in this case I lose the scrollbars(not to mention the impact on my view). So what I would like is to set this property to false and dynamically affect the horizontal scrollbar's position, in other words enable scrolling without the clipping.

How can I Access Items Selected in a Component from the Main App I've got a component that has a listControl and a couple of RadioButtonGroups. I need to access the selected items in the main application. What's the best/simplest way to create and access the array of selected items. So, the user clicks the button to confirm the selections and then I need to access those selections in the main app. Is there a way I can use a public var to build the array? Another idea?
<mx:Tile direction="horizontal">
<mx:Box>
<mx:Label text="Year" fontWeight="bold"/>
<mx:List id="myYear" >

I have a public variable set within fx:Script tags in a parent component that I'd like to access directly from a child component. How can I do this? I don't want to pass the variable to the child component (I know how to do this and am currently using this approach). Following is a simplified version of the mxml:
