hotspot

The class of a hotspot object. Hotspots are invisible rectangular regions on a window that can receive and respond to events just as actual windows do. They can be used to overlay images drawn on a window in order to make the images behave as graphical objects without using a separate child window that would obscure overlapping images on the main window.

The mouse-in, mouse-out, and various mouse click methods such as mouse-left-down are invoked for hotspot instances just as it is for windows. If you define mouse click methods for hotspots, the methods should return nil if you want the click to be further processed by the hotspot's parent window, or non-nil to prevent further processing of the click by the window.
