Has anyone been able to successfully load a TileList into an
ActionScript project without using MXML?
If so, can you please help me out?
Code Snippet:
public var t:TileList = new TileList();
public function Entertainment()
{
t.x = 5;
t.y = 5;
t.addItem( {label:'Robert', data:'Roebrt'} );
t.setSize(316, 251);
t.columnWidth = 310;
t.direction = ScrollBarDirection.VERTICAL;
t.cacheAsBitmap = true;
t.allowMultipleSelection = false;
//t.horizontalScrollPosition = 30;
t.setStyle("cellRenderer", Thumb);
addChild(t);
}
ERRORS:
I am trying to simply add a TileList component to my application. The
error I am getting is that nasty Error: #1009:
Main Thread (Suspended: TypeError: Error #1009: Cannot access a property
or method of a null object reference.)
fl.containers::BaseScrollPane/drawBackground
fl.controls::TileList/draw
fl.core::UIComponent/callLaterDispatcher
After review, the error occurs in the fl/containers/BaseScrollPane.as
file on line 983. This is because the following method:
var bg:DisplayObject = background;
background = getDisplayObjectInstance(getStyleValue("skin")); // This
returns a NULL
background.width = width; // Here is the ERROR because I try to use a
property of a NULL object.
//---------------------------
I figured that this is something to do with the application trying to
draw the TileList before its time, or something to that effect. I have
no trouble adding a TileList component using Flash CS3 but in this
application it is complete as with NO Flash intervention nor any MXML
files, therefore dragging a component to the stage is not an option.
//----------------------------
Has anyone run into a similar issue. In the above example, I am simply
using an AS file attempting to add a TileList component to the stage.
When I invoke the addChild(TileListComponentInstance) is when I get the
above error. If I comment out this line (addChild) I will not get an
error.!?!?
