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.
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.

The following example draws the specified cursor on the form in its normal size, and in stretched mode, twice its size. This example assumes that you have a Form and a Cursor object to pass into the method when it is called.
private void DrawCursorsOnForm(Cursor cursor) { // If the form's cursor is not the Hand cursor and the // Current cursor is the Default, Draw the specified // cursor on the form in normal size and twice normal size. if(this.Cursor != Cursors.Hand & Cursor.Current == Cursors.Default) { // Draw the cursor stretched. Graphics graphics = this.CreateGraphics(); Rectangle rectangle = new Rectangle( new Point(10,10), new Size(cursor.Size.Width * 2, cursor.Size.Height * 2)); cursor.DrawStretched(graphics, rectangle); // Draw the cursor in normal size. rectangle.Location = new Point( rectangle.Width + rectangle.Location.X, rectangle.Height + rectangle.Location.Y); rectangle.Size = cursor.Size; cursor.Draw(graphics, rectangle); // Dispose of the cursor. cursor.Dispose(); } }
