Dear all,
i have the followig problem , i have using AS3 to created a
custom component (extends from UIComponent) , i find that the custom
component cannot display on the screen. But if the component extends
from HBox , it will show correctly . Can someone tell me why?
The code is attached.

public function test_item(){
super();
}
override protected function createChildren():void {
super.createChildren();
if (!item_button){
item_button = new Button();
item_button.label = "As";
addChild(item_button);
}
}
override protected function measure():void{
super.measure();
measuredWidth = measuredMinWidth = 410;
measuredHeight = measuredMinHeight = 30;
