GdkEventCrossing

detail GdkNotifyType detail;: the kind of crossing that happened (gdk.types.NotifyType.Inferior, gdk.types.NotifyType.Ancestor, gdk.types.NotifyType.Virtual, gdk.types.NotifyType.Nonlinear or gdk.types.NotifyType.NonlinearVirtual).
focus gboolean focus;: true if @window is the focus window or an inferior.
mode GdkCrossingMode mode;: the crossing mode (gdk.types.CrossingMode.Normal, gdk.types.CrossingMode.Grab, gdk.types.CrossingMode.Ungrab, gdk.types.CrossingMode.GtkGrab, gdk.types.CrossingMode.GtkUngrab or gdk.types.CrossingMode.StateChanged). gdk.types.CrossingMode.GtkGrab, gdk.types.CrossingMode.GtkUngrab, and gdk.types.CrossingMode.StateChanged were added in 2.14 and are always synthesized, never native.
sendEvent byte sendEvent;: true if the event was sent explicitly.

subwindow GdkWindow* subwindow;: the window that was entered or left.
time uint time;: the time of the event in milliseconds.
type GdkEventType type;: the type of the event (gdk.types.EventType.EnterNotify or gdk.types.EventType.LeaveNotify).
window GdkWindow* window;: the window which received the event.
x double x;: the x coordinate of the pointer relative to the window.
xRoot double xRoot;: the x coordinate of the pointer relative to the root of the screen.
y double y;: the y coordinate of the pointer relative to the window.
yRoot double yRoot;: the y coordinate of the pointer relative to the root of the screen.
