The player's is-the-mouse-over-this-DisplayObject logic checks whether the mouse is over a part of the DisplayObject that has been drawn into. This lets a DisplayObject have non-rectangular hit areas.
If you haven't drawn into the Sprite, the mouse can't detect it at all. If the Sprite has any background color (including white or the background color or whatever), all of it has been drawn into, and the whole thing is the hit area. If you draw a circle or something into the sprite, you'll get a mouseOver only for that circle. But "drawn into" isn't the same as "visible". If you need a visually transparent area that the mouse can detect, the trick is to draw into that area with zero alpha! You can probably get this to happen by setting backgroundAlpha="0" on your renderer. - Gordon -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Greg Morphis Sent: Wednesday, January 04, 2006 1:00 PM To: [email protected] Subject: [flexcoders] Re: custom cell renderer onMouseover.. This is strange!!! If we set the backgroundColor then I can mouseOver from the text to the image.. if we do not then the mouseOver only works on the text.. WTF?? Is there a way for the cellrenderer to know what row the user is on (in the below code)? I suppose I could set the backgroundColor back to the row color defined in the datagrid? This sounds like a bug though...
