the kind of crossing that happened (%GDK_NOTIFY_INFERIOR, %GDK_NOTIFY_ANCESTOR, %GDK_NOTIFY_VIRTUAL, %GDK_NOTIFY_NONLINEAR or %GDK_NOTIFY_NONLINEAR_VIRTUAL).
%TRUE if window is the focus window or an inferior.
the crossing mode (%GDK_CROSSING_NORMAL, %GDK_CROSSING_GRAB, %GDK_CROSSING_UNGRAB, %GDK_CROSSING_GTK_GRAB, %GDK_CROSSING_GTK_UNGRAB or %GDK_CROSSING_STATE_CHANGED). %GDK_CROSSING_GTK_GRAB, %GDK_CROSSING_GTK_UNGRAB, and %GDK_CROSSING_STATE_CHANGED were added in 2.14 and are always synthesized, never native.
%TRUE if the event was sent explicitly.
a bit-mask representing the state of the modifier keys (e.g. Control, Shift and Alt) and the pointer buttons. See #GdkModifierType.
the window that was entered or left.
the time of the event in milliseconds.
the type of the event (%GDK_ENTER_NOTIFY or %GDK_LEAVE_NOTIFY).
the window which received the event.
the x coordinate of the pointer relative to the window.
the x coordinate of the pointer relative to the root of the screen.
the y coordinate of the pointer relative to the window.
the y coordinate of the pointer relative to the root of the screen.
Generated when the pointer enters or leaves a window.
