GI.Gdk.Structs.EventButton

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.
