#include "l_bitmap.h"

L_LTANN_API L_INT L_AnnSetRestrictToContainer(hObject, bRestrict, uFlags)

HANNOBJECT hObject;

handle to the annotation object

L_BOOL bRestrict;

flag that specifies whether to restrict the object to the container

L_UINT uFlags;

flags that determine which objects to process

Restricts one or more annotation objects to a container.

Parameter Description
hObject Handle to the annotation object
bRestrict Boolean value that specifies whether to restrict the object to the container. Possible values are:
  Value Meaning
  TRUE Restrict the object to the container.
  FALSE Do not restrict the object to the container.
uFlags Flags that determine which objects to process. Possible values are:
  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_AnnSetSelected 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.
  ANNFLAG_CHECKMENU [0x0020] Process objects only if the ANNAUTOTEXT_MENU_BACKGROUNDCOLOR menu item has been selected.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

If an object is restricted to the container, then no part of that object can be moved outside of the container using automation.

All annotation objects support restriction.

Example

This example toggles the "restrict to container" property of the annotation to the container. If an object is restricted to the container, no part of it can be moved outside the container.

L_INT AnnSetRestrictToContainerExample(HANNOBJECT hObject)

   L_INT nRet; 
   L_BOOL   bRestrict; 
   L_TCHAR* pszMsg; 
 
   nRet = L_AnnGetRestrictToContainer(hObject, &bRestrict); 
   if (nRet == SUCCESS) 
   { 
      bRestrict = !bRestrict; 
      L_AnnSetRestrictToContainer(hObject, bRestrict, 0); 
      pszMsg = bRestrict ? TEXT("Restricted to container") : TEXT("Not restricted to container"); 
      MessageBox(NULL, pszMsg, TEXT(""), MB_OK); 
   } 
   else 
      return nRet; 
   return SUCCESS;
