Hot Spots

Hot spots are a convenient way to add user interaction to objects (or controls) without going to the overhead of using Windows controls (standard, custom, or otherwise). With hot spots you can add clickable bitmap areas (the '?' help button in check box controls), or even Right mouse click short-cut menus.

Clickable bitmap areas can also be seen below in the edit, combo and graph objects.

Most objects with hotspots provide a property to turn the hotspot off.
