Event Structures
A common mistake is to forget to set the event mask of a widget so that the
required events are received. See gtk_widget_set_events().
Contains the fields which are common to all event structs.
Any event can safely be cast to a #GdkEventAny to access these fields.
@type: the type of the event.
@window: the window which received the event.
@send_event: TRUE if the event was sent explicitly (e.g. using XSendEvent).

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 treble-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.
Treble-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
@type: the type of the event.
@window: the window which received the event.
@send_event: TRUE if the event was sent explicitly (e.g. using XSendEvent).
@time: the time of the event in milliseconds. This wraps around roughly every
50 days.
@x: the x coordinate of the mouse relative to the window.
@y: the y coordinate of the mouse relative to the window.
@pressure: the pressure of the button press, intended for input devices such
as graphics tablets. It defaults to 0.5.

@x_root: the x coordinate of the mouse relative to the root of the screen.
@y_root: the y coordinate of the mouse relative to the root of the screen.
