LAnnContainer::Enumerate

Summary

Lets you process all of the annotation objects in a Container.

Syntax

#include "ltwrappr.h"

virtual L_INT LAnnContainer::Enumerate(uFlags=ANNFLAG_SELECTED, pUserList=NULL)

Parameters

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 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.

L_TCHAR *pUserList

Character string that contains the list of users associated with the specified object. pUserList has the form "User1,User2,,UserN". This must be a NULL terminated string with user names separated by a comma. This parameter is valid only if ANNFLAG_USER is set in uFlags.

Returns

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

Comments

The LAnnContainer::Enumerate function calls LAnnContainer::EnumerateCallBack as it gets the handle of each annotation object.

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!
