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, and 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. GdkEventType type; the type of the event (GDK_BUTTON_PRESS, GDK_2BUTTON_PRESS, GDK_3BUTTON_PRESS or GDK_BUTTON_RELEASE). GdkWindow *window; the window which received the event. gint8 send_event; TRUE if the event was sent explicitly (e.g. using XSendEvent). guint32 time; the time of the event in milliseconds. gdouble x; the x coordinate of the pointer relative to the window. gdouble y; the y coordinate of the pointer relative to the window. gdouble *axes; x, y translated to the axes of device, or NULL if device is the mouse. guint state; a bit-mask representing the state of the modifier keys (e.g. Control, Shift and Alt) and the pointer buttons. See GdkModifierType. guint button; the button which was pressed or released, numbered from 1 to 5. Normally button 1 is the left mouse button, 2 is the middle button, and 3 is the right button. On 2-button mice, the middle button can often be simulated by pressing both mouse buttons together. GdkDevice *device; the device where the event originated. gdouble x_root; the x coordinate of the pointer relative to the root of the screen. gdouble y_root; the y coordinate of the pointer relative to the root of the screen.
