L_ContainerSetObjectCursor

#include "LtCon.h"

L_LTCON_API L_INT L_ContainerSetObjectCursor (pContainer, nObjectType, hCursor)

pCONTAINERHANDLE pContainer;	/* pointer to a container handle */
CONTAINEROBJECTTYPE nObjectType;	/* container object type */
L_HCURSOR hCursor;	/* handle to a windows cursor */

Sets the container object cursor.

Parameter	Description
pContainer	Pointer to a container handle.
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	The new object cursor.

Returns

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 ContainerSetObjectCursorExample(HWND hWnd, pCONTAINERHANDLE * ppContainer)
{
   L_INT nRet;
   CONTAINERMETRICS Metrics ;
   /* Initiate the container handle */
   nRet = L_ContainerInit ( ppContainer ) ;
   if(nRet != SUCCESS)
      return nRet;
   /* Create the container and attach it to its owner window */
   nRet = L_ContainerCreate ( *ppContainer, hWnd ) ;
   if(nRet != SUCCESS)
      return nRet;
   nRet = L_ContainerIsValid ( *ppContainer );
   if (SUCCESS == nRet ) /* check the validity of the container handle */
   {
      HCURSOR hRectCursor ;
      /* Load some cursor */
      hRectCursor = LoadCursor ( NULL, IDC_CROSS ) ;
      /* Set the rectangle object cursor */
      nRet = L_ContainerSetObjectCursor ( *ppContainer, CONTAINER_OBJECT_TYPE_RECT, hRectCursor ) ;
      if(nRet != SUCCESS)
         return nRet;
      /* Destroy the cursor, because its not needed any more */
      DestroyCursor ( hRectCursor ) ;
      /* Set the container object type to rectangle */
      nRet = L_ContainerSetObjectType ( *ppContainer, CONTAINER_OBJECT_TYPE_RECT ) ;
      if(nRet != SUCCESS)
         return nRet;
      /* Initiate the container metrics */
      Metrics.nSize   = sizeof ( CONTAINERMETRICS ) ;
      Metrics.dwMask = CMF_LIMITS ;
      /* Set the container limits to some value */
      SetRect ( &Metrics.rcLimits, 0, 0, 500, 500 ) ;
      /* Set the container metrics */
