GdkEventButton

Used for button press and button release events. The type field will be one of GDK_BUTTON_PRESS, GDK_2BUTTON_PRESS, GDK_3BUTTON_PRESS or GDK_BUTTON_RELEASE, Double and triple-clicks result in a sequence of events being received. For double-clicks the order of events will be: GDK_BUTTON_PRESS GDK_BUTTON_RELEASE GDK_BUTTON_PRESS GDK_2BUTTON_PRESS GDK_BUTTON_RELEASE Note that the first click is received just like a normal button press, while the second click results in a GDK_2BUTTON_PRESS being received just after the GDK_BUTTON_PRESS. Triple-clicks are very similar to double-clicks, except that GDK_3BUTTON_PRESS is inserted after the third click. The order of the events is: GDK_BUTTON_PRESS GDK_BUTTON_RELEASE GDK_BUTTON_PRESS GDK_2BUTTON_PRESS GDK_BUTTON_RELEASE GDK_BUTTON_PRESS GDK_3BUTTON_PRESS GDK_BUTTON_RELEASE For a double click to occur, the second button press must occur within 1/4 of a second of the first. For a triple click to occur, the third button press must also occur within 1/2 second of the first button press.
