TKButton allows the creation and activation of region defined buttons that conform to ANY shape. It can create a full mask or use the "literal" graphics.
This XFCN is a companion to the ToolKit‚Ñ¢ Button Editor but can be used alone to create and manage a region button. You simply pass TKButton a list of button names, along with any desired effects command. If a hit occurs the name of the target button is returned.
