L_INT LContainer::SetObjectCursor (nObjectType, hCursor)
Sets the container object cursor.
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 |
The new object cursor.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
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.
