Hi guys,

I've just started making an app for the PlayBook so pardon my "n00b-ishness".

I have a simple question about drop down menus. My code is below. When I view this on the simulator I get a drop down with just the word "Background" and when I click on the arrow, I get one blank line. Nothing inside it. I've searched the forums and can't find anything specific to this one. Please let m e know.

var backgroundOptions:DropDown = new DropDown();
			backgroundOptions.rowCount = 8;
			backgroundOptions.rowHeight = 30;
			backgroundOptions.prompt = "Background";
			backgroundOptions.x = 20;
			backgroundOptions.y = 300;
			var dp:DataProvider = new DataProvider();
			var listOfBackgrounds:Array = new Array([{label: 'Black'},
				{label: 'Green'},
				{label: 'Blue'},
				{label: 'White'},
				{label: 'Slow Lines'},
				{label: 'Abstract'},
				{label: 'Lines'},
				{label: 'Aurora'}]);
			
			dp.setItems(listOfBackgrounds);
			backgroundOptions.dataProvider = dp;
			addChild(backgroundOptions);

Any help would be great!

Thanks!

Try:

var backgroundOptions:DropDown = new DropDown();
backgroundOptions.rowCount = 8;
backgroundOptions.rowHeight = 30;
backgroundOptions.prompt = "Background";
backgroundOptions.x = 20;
backgroundOptions.y = 300;
			
var listOfBackgrounds:Array = new Array([{label: 'Black'},
				{label: 'Green'},
				{label: 'Blue'},
				{label: 'White'},
				{label: 'Slow Lines'},
				{label: 'Abstract'},
				{label: 'Lines'},
				{label: 'Aurora'}]);
			
backgroundOptions.dataProvider = new DataProvider( listOfBackgrounds );
addChild( backgroundOptions );

Hey jtegen,

I tried the solution you posted, but unfortunately I still get the same blank line as the first.

Sorry.

I see it now.  You're creating an array of arrays.  Try:

var listOfBackgrounds:Array = new Array({label: 'Black'},
				{label: 'Green'},
				{label: 'Blue'},
				{label: 'White'},
				{label: 'Slow Lines'},
				{label: 'Abstract'},
				{label: 'Lines'},
				{label: 'Aurora'});

No square brackets in the Array constructor.  Just an array of objects.

Perfect kind sir!

It worked!

Thanks so much! I've been racking my brain since 8am this morning and its 1.30pm now.

Time for a break maybe?

Just think, you'll never make that mistake in your lifetime again (or for at least a week).

Good luck.
