HotSpot Annotation Object

(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:

Property Defaults
Active state Defaults to disabled. It can be changed using the L_AnnSetActiveState function.
Visible Defaults to FALSE. It can be changed using the L_AnnSetVisible function.
Selected Defaults to FALSE. It can be changed using the L_AnnSetSelected function.
Name Defaults to an empty string. It can be changed using the L_AnnSetNameOptions function.
Metafile Defaults to a campfire graphic. It can be changed using the L_AnnSetMetafile function.
Fixed State Defaults to not fixed. It can be changed using the L_AnnSetFixed function.
Hyperlink Defaults to None. It can be changed using the L_AnnSetHyperlink function.
Tag (identifier) Defaults to 0. It can be changed using the L_AnnSetTag function.
Window handle Defaults to NULL or the handle inherited from the container. It can be changed for all objects using the L_AnnSetWnd function.
User mode Defaults to design mode or the mode inherited from the container. It can be changed for all objects using the L_AnnSetUserMode function.
