Detailed Description

Interface to reference icons from within bWidgets.

Using this interface, bWidgets can reference icon objects of which it doesn't know any implementation details.

To get icon drawing to work you have to:

• implement this interface as some class for storing icon data (e.g. a bitmap wrapper),
• implement the bwPaintEngine::drawIcon() function for drawing the icon data,call the setIcon function of a widget (if available) to set the icon reference. Managing icons, including their memory, has to be done outside of bWidgets. At no point does bWidgets take ownership over icon data.
