Re: [flexcoders] Re: Newbie Question - attaching a Sprite

[Tom Bray]

Here's a response from Gordon to a similar question I had way back:What does your component extend? If you're
extending a Container, you can only use addChild() to content children which implement
the IUIComponent interface. In order to support the LayoutManager, a content
child has to implement things like measure(), etc.

 

However you should able to add it as a
non-content or "chrome" child by doing rawChildren.addChild(myButton).
Non-content children don't undergo automatic sizing and layout, so you'll have
to set the size and position of myButton yourself.

            I thought so too, as it even says in the addChild for a Canvas
documentation that it takes a display object. 

but for some reason when I test and after attaching the canvas I then
attach the sprite I still get that same error:

"TypeError: Error #1034: Type Coercion failed: cannot convert
flash.display::[EMAIL PROTECTED] to mx.core.IUIComponent."

Why would it try to convert that?

this is the bit of code from the function , and the drawn bg and the
button show up totally fine.

contentBg = new Canvas();
contentBg.graphics.beginFill(0xFF0000);
contentBg.graphics.lineStyle(2, 0xFFFFFF);
contentBg.graphics.drawRoundRect(0, 0, 150, 400, 10, 10);
contentBg.graphics.endFill();
addChild(contentBg);
			
changeButton = new Button();
changeButton.label = returnData.buttons.button.label;
changeButton.move(30, 30);
changeButton.addEventListener(MouseEvent.CLICK, someFunction);
contentBg.addChild(changeButton);
			
mySprite = new Sprite();
mySprite.graphics.beginFill(0xFFFFFF);
mySprite.graphics.drawRoundRect(300, 0, 150, 400, 10, 10);
mySprite.graphics.endFill();
contentBg.addChild(mySprite);

any ideas?
