Pointer cursor.

The pointer cursor is created in a similar way to a sprite. After creating it, one or more sprite members containing the bitmaps to be displayed are added.

After a pointer cursor has been created and activated, it does not become visible until the application calls RWindowTreeNode::SetPointerCursor() or RWindowTreeNode::SetCustomPointerCursor(). The pointer cursor's origin automatically tracks the position of the pointing device, or position of emulated single pointer if there are more pointers in the system (see documentation of RWindowBase::EnableAdvancedPointers() for more details), and the origin forms the pointer cursor's "hot spot", i.e., the point whose co-ordinates are sent to the client if a pointer event occurs. If the pointer cursor's bitmap needs to extend to the left or upwards from the pointer position, its sprite member should be given a negative offset in TSpriteMember::iOffset.

Note:

Pointer cursors are rarely used in pure pen architectures, but they are supported for mouse or tablet use.
