LAnnotation::Destroy

#include "ltwrappr.h"

virtual L_INT LAnnotation::Destroy(uFlags=0)

L_UINT uFlags;

/* flags that determine which objects to process */

Deletes the annotation object and frees the memory used to store it. This function is available in the Document/Medical Toolkits.

Parameter	Description
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 LAnnContainer::GetSelectItems and LAnnotation::SetSelected 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.

Returns

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

Comments

This does not destroy the class object.

This function applies to multiple and selected objects based on values of the uFlags parameter.

You should not call this function during processing of WM_LTANNEVENT if wParam equals LTANNEVENT_REMOVE or LTANNEVENT_INSERT or during the LAnnContainer::EnumerateCallBack virtual function!
