(Document and Medical Imaging toolkits)
The HotSpot annotation object (ANNOBJECT_HOTSPOT) is a rectangle that can be activated for an application-defined purpose. With the automated functions, in design mode, the rectangle contains a scaled image. The user clicks and drags to specify the rectangle in the current window. In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object. Clicking on the button sends a WM_LTANNEVENT message that indicates an activation event.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must specify the defining rectangle. Other applicable properties have the following defaults, which you can change:
