I cannot add VBox in UIComponent?

[HW2002]

Hello,

Whenver I add VBox container to UIComponent it never occurs on the screen, but when I added it to Application.application.addChild(vbox) then it become visible?

Can I only add Vbox to the application and not to a uicomponent? or what?

Someone please explain and thanks for your help.

Regards,

Maybe the UIComponent you're adding it to isn't in the display list yet?

You guys need to stop putting these threads in the AS 3.0 forum. There's a Flex forum dedicated to this.

If you're adding a child to a plain UIComponent, you need to remember to explicitly set the size of it's children or they won't be visible. Flex containers will do it automatically, but you have more control in UIComponents.

var w:Number = myVBox.getExplicitOrMeasuredWidth();
var h:Number = myVBox.getExplicitOrMeasuredHeight();
myVBox.setActualSize(w, h);
