Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
Some of the Cursor objects in this class can take on a different appearance than those described. The user can change the cursor appearance by adjusting the mouse pointer settings in their operating system. The panning and no move cursors are static and cannot be changed by the operating system.
The panning and no move cursors are used during mouse wheel operations. Depending on the direction the window can be scrolled, the cursor changes to the appropriate no move cursor when the mouse wheel is clicked. The cursor then changes to the appropriate panning cursor as the mouse is moved.
Example
[Visual Basic, C#, C++] The following example demonstrates changing the mouse cursor using the Control.Cursor property, the Cursor class, and the Cursors class. The example creates a form that contains a ComboBox control, a Panel control, and a ListView control. The ComboBox contains all cursors provided by the Cursors class. When the user selects a mouse cursor in the ComboBox, the Control.Cursor property is set to the selected cursor, which updates the cursor for the Panel. The ListView is updated every time the Control.CursorChanged event occurs.
