/**
 * GdkEventButton:
 * @type: the type of the event (%GDK_BUTTON_PRESS, %GDK_2BUTTON_PRESS,
 *   %GDK_3BUTTON_PRESS or %GDK_BUTTON_RELEASE).
 * @window: the window which received the event.
 * @send_event: %TRUE if the event was sent explicitly (e.g. using
 *   <function>XSendEvent</function>).
 * @time: the time of the event in milliseconds.
 * @x: the x coordinate of the pointer relative to the window.
 * @y: the y coordinate of the pointer relative to the window.
 * @axes: @x, @y translated to the axes of @device, or %NULL if @device is
 *   the mouse.
 * @state: (type GdkModifierType): a bit-mask representing the state of
 *   the modifier keys (e.g. Control, Shift and Alt) and the pointer
 *   buttons. See #GdkModifierType.
 * @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.
 * @device: the device where the event originated.
 * @x_root: the x coordinate of the pointer relative to the root of the
 *   screen.
 * @y_root: the y coordinate of the pointer relative to the root of the
 *   screen.
 *
 * 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:
 * <orderedlist>
 * <listitem><para>%GDK_BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
 * <listitem><para>%GDK_BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_2BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
 * </orderedlist>
 * 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:
 * <orderedlist>
 * <listitem><para>%GDK_BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
 * <listitem><para>%GDK_BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_2BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
 * <listitem><para>%GDK_BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_3BUTTON_PRESS</para></listitem>
 * <listitem><para>%GDK_BUTTON_RELEASE</para></listitem>
 * </orderedlist>
 *
 * 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.
