Selects or deselects the specified annotation object.

L_LTANN_API L_INT L_AnnSetSelected(hObject, fSelected, uFlags)



Handle to the annotation object.

L_BOOL fSelected

Flag that indicates whether to select or deselect an object. Possible values are:

Value Meaning
TRUE Select the specified object and all objects that it contains.
FALSE Deselect the object and all objects that it contains.

L_UINT uFlags

Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:

Value Meaning
0 Process only the specified object.
ANNFLAG_SELECTED [0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the L_AnnGetSelected and [L_AnnSetSelectedfunctions functions.
ANNFLAG_NOTTHIS [0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.
ANNFLAG_RECURSE [0x0008] Process objects within a container, and within any subcontainers, down to any level.
ANNFLAG_NOTCONTAINER [0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.
ANNFLAG_NOINVALIDATE [0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.


Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.


Most L_AnnSetXXX functions let you change properties of selected objects in a container. Therefore, if you set individual objects' selected properties to TRUE, you can then use the other L_AnnSetXXX functions on the container to change the properties of only those objects in the container that have been selected.

This function applies to multiple and selected objects based on values of the uFlags parameter. The possible flags are the same as for other L_AnnSetXXX functions.
