how to change the Focus area to be transparent

Options

Hello,

 

I have a bitmapField. When I have the trackball focused on this bitmapField, the transparent area of this bitmap is highlighted to the Blue. Is it possible to have the highlighted area still been transparent, just like when we use windows XP,the highlighted area is still transparent even though we click on an icon on desktop?

 

Some sample code will be great! I just started blackberry java development 2 weeks ago.

You can extend the BitmapField and override the method drawFocus( Graphics graphics, boolean on ).  Just change this method to draw your bitmap using the graphics.drawBitmap() function.
