Hi,

I want to change the background color of the screen, i have used the following code but it doesn't worked out, can anyone help me please

package
{

    [SWF( frameRate="30", backgroundColor="0xFFFFFF", width="800", height="600" )]
    public class MyDocumentClass extends Sprite
    {
        public function MyDocumentClass()
        {
            super();
        }
    }
}

Even i tried the following

graphics.beginFill(0xBBBBBB, 1);
graphics.drawRect(0, 0, 800, 600);
graphics.endFill();

But melt down, please help

The background colour is set with HTML notation. You use #FFFFFF or #BBBBBB.

Hey ramesh,

Try changing the width value to 1024. The width of the playbook screen is actually 1024.

Edit: i tried copy and pasting your exact line:

[SWF( frameRate="30", backgroundColor="#FFF000", width="800", height="600" )]

and it worked fine even before changing the width to 1024 and got a yellow background. maybe you arent inserting that bit of code into the rite place. what is the exact code you are writing for your app?

Edit #2: i just noticed you were missing the Sprite class import in your initial code. copy and paste the following code:

package
{
	import flash.display.Sprite;
	
	// The following metadata specifies the size and properties of the canvas that
	// this application should occupy on the BlackBerry PlayBook screen.
	[SWF(width="1024", height="600", backgroundColor="#FFF000", frameRate="30")]
	public class MyDocumentClass extends Sprite
	{
		public function MyDocumentClass()
		{
			
		}
	}
}

that should give you a grey yellow background. hope that helps!

Here where i am placing the code

[SWF( frameRate="30", backgroundColor="#FFF000", width="800", height="600" )]

public class Page1 extends Sprite
 {

 var btn:Button = new Button();
   var lab:Label = new Label();
   page2 = new Page2();
   lab.text = "Click";
   btn.addChild(lab);
   btn.setPosition(10,50);
   btn.addEventListener(MouseEvent.CLICK,dothis);
   addChild(btn);
   stage.nativeWindow.visible = true;
   
  }

}

any help ?

here is what i pasted in the other thread that seems to pertain to this thread too.

again assuming all your classes are set up this should run:

package
{
	//Remember to import all of the classes that you
	//are using
	import flash.display.Sprite;
	import flash.events.MouseEvent;
	
	import qnx.ui.buttons.LabelButton;
	
	// The following metadata specifies the size and properties of the canvas that
	// this application should occupy on the BlackBerry PlayBook screen.
	[SWF(width="1024", height="600", backgroundColor="#FFF000", frameRate="30")]
	public class Page1 extends Sprite
	{
		private var page2:Page2;
		
		public function Page1()
		{
			//initiate new object here to use later
			page2 = new Page2();
			
			var labButton:LabelButton = new LabelButton();
			
			labButton.label = "Click";
			labButton.setPosition(10,50);
			labButton.addEventListener(MouseEvent.CLICK,dothis);
			
			addChild(labButton);
			
			//addChild(log); //dont know where you declared this so commented out
			stage.nativeWindow.visible = true;
		}
		//change the event to MouseEvent since that is what you
		//are listening for
		public function dothis(event:MouseEvent):void {
			
			addChild(page2);
			//addChild(log); //dont know where you declared this so commented out
			
		}   
	}
}

remember to import all your class definitions inlcuding Sprites, Events, etc. also remember whatever event you are listening for you have that same event in your listener. good luck!

I actually had the same problem before when I first started coding.

I don't think its in the code.  What happened was i couldn't get my head around why it wasn't changing so i just copied and pasted the HelloWorld example over and it still didn't work.

I just restarted a new flex application and restarted a new file.  Sure enough that did the trick.

It might be a bug, or the application wasn't set up properly.  But try starting a new file.

Let me know how it goes.
