LContainer::SetObjectCursor

#include "Ltwrappr.h"

L_INT LContainer::SetObjectCursor (nObjectType, hCursor)

Sets the container object cursor.

Parameters

CONTAINEROBJECTTYPE nObjectType

An integer that represents the object type for which to set the cursor. Possible values are:

Value Meaning
CONTAINER_OBJECT_TYPE_POINT Point object
CONTAINER_OBJECT_TYPE_LINE Line object
CONTAINER_OBJECT_TYPE_SQUARE. Square object
CONTAINER_OBJECT_TYPE_RECT Rectangular object
CONTAINER_OBJECT_TYPE_ELLIPSE Elliptical object
CONTAINER_OBJECT_TYPE_CIRCLE Circular object
CONTAINER_OBJECT_TYPE_POLYLINE Polyline object
CONTAINER_OBJECT_TYPE_BEZIER Bezier curve object
CONTAINER_OBJECT_TYPE_ARC Arc object
CONTAINER_OBJECT_TYPE_TEXT Text object

HCURSOR hCursor

The new object cursor.

Returns

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

Comments

The cursor set by this function will be shown every time that specific object type is drawn in the container. For example, if a rectangle is being drawn in the container, the cursor set for object type CONTAINER_OBJECT_TYPE_RECT will be displayed. The container makes a copy of the cursor. Therefore, the user can delete a specific cursor.

Example

This example shows how to set some container object cursor.

L_INT LContainer_SetObjectCursorExample( HWND hWnd, LContainer & lcont)

   nRet = lcont.Initialize () ; 
   if(nRet != SUCCESS) 
      return nRet;

   nRet = lcont.Create (hWnd ) ; 
   if(nRet != SUCCESS) 
      return nRet; 
 
   nRet = lcont.IsValid ( );
