As you https://forums.adobe.com/thread/1333070 know flash builder does not include fl.controls package by default. I have added this package to my project as source path or swc file so that I can use the default components (e.g. Buttons, RadioButtons, Checkboxes) and now I am writing the following code.package{ import flash.display.Sprite; import fl.controls.Button; [SWF(width = "640", height = "480", frameRate = "60", backgroundColor = "#FFFFFF")] public class Test extends Sprite { private var btn:Button; public function Test() { btn = new Button(); btn.label = "CLICK ME!"; btn.x = 100; btn.y = 100; addChild(btn); } }}I am creating a fl.controls.Button instance in Test class and trying to add it on stage. When I run the project, it always gives me the following error for the bold red line.TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/addChildAt() at fl.controls::BaseButton/drawBackground()[C:\Program Files (x86)\Adobe\Adobe Flash CS5.5\Common\Configuration\Component Source\ActionScript 3.0\User Interface\fl\controls\BaseButton.as:615] at fl.controls::LabelButton/draw()[C:\Program Files (x86)\Adobe\Adobe Flash CS5.5\Common\Configuration\Component Source\ActionScript 3.0\User Interface\fl\controls\LabelButton.as:724] at fl.controls::Button/draw()[C:\Program Files (x86)\Adobe\Adobe Flash CS5.5\Common\Configuration\Com

All fine - now! Reply With Quote August 20th, 2014,08:09 AM #
