Freehand HotSpot Annotation Object

The Freehand HotSpot annotation object (ANNOBJECT_FREEHANDHOTSPOT) is an array of points that create a sequence of joined lines. With the automated functions, in design mode, each line segment is formed with a mouse move event when the left button is down, and the object is completed on a mouse up event. 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.

The class for Freehand HotSpot Annotation objects is LAnnFreehandHotSpot.

You can change the points of a freehand object using LAnnFreehand::GetPoints and LAnnFreehand::AnnSetPoints.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:

Property Default value
Visible Defaults to FALSE. It can be changed using the LAnnotation::SetVisible function.
Selected Defaults to FALSE. It can be changed using the LAnnotation::SetSelected function.
Name Defaults to an empty string. It can be changed using the LAnnotation::SetNameOptions function.
Line width Defaults to 0.75 points. It can be changed using the LAnnXXX::SetLineWidth function. (Note that when displayed, the line must have a minimum width of 1 pixel.)
Line style Defaults to solid. It can be changed using the LAnnXXX::SetLineStyle function.
ROP2 code Defaults to ANNROP2_COPY. It can be changed using the LAnnotation::SetROP2 function.
Nodes Defaults to displaying every node. It can be changed using the LAnnXXX::SetNodes function.
Hotspot Metafile Defaults to a campfire graphic. It can be changed using the LAnnXXX::SetMetafile function.
Fixed State Defaults to not fixed. It can be changed using the LAnnXXX::SetFixed function.
Hyperlink Defaults to ANNLINK_NONE. It can be changed using the LAnnotation::SetHyperlink function.
Tag (identifier) Defaults to 0. It can be changed using the LAnnotation::SetTag function.
Window handle Defaults to NULL or the handle inherited from the container. It can be changed for all objects using LAnnContainer::SetWnd.
