.NET Windows Forms in a Nutshell

Name

MouseEventArgs

Synopsis

This class encapsulates the data for the Control.MouseDown, Control.MouseUp, and Control.MouseMove events. You can determine the X and Y coordinates of the mouse (in client coordinates—contrast this with Control.MousePosition), the Button that was pressed (note that this is the button that caused the event, not the total set of buttons currently depressed—you should use Control.MouseButtons for this information).

You can also determine the number of Clicks that have occurred (i.e., single, double, triple, etc.), and the Delta through which the mouse wheel has rotated.
