CMCursorChanged is an overridden method in TGraphicControl. It ensures that the control is Visible before the temporary cursor shape is changed.
Visible must be set to True, and the Parent control (with the window handle) must be assigned before the control can be displayed. No actions are performed in the method if Visible is False, or Parent is Nil.
In addition, the mouse must be over the control to apply the cursor shape using SetTempCursor and the value in the Cursor property.
