type

The gdk:event-type type of the event.

window

The gdk:window object which received the event.

send-event

True if the event was sent explicitly.

subwindow

The gdk:window object that was entered or left.

time

The unsigned integer with the time of the event in milliseconds.

x

The double float x coordinate of the pointer relative to the window.

y

The double float y coordinate of the pointer relative to the window.

x-root

The double float x coordinate of the pointer relative to the root of the screen.

y-root

The double float y coordinate of the pointer relative to the root of the screen.

mode

The gdk:crossing-mode value.

detail

The gdk:notify-type kind of crossing that happened.

focus

True if window is the focus window or an inferior.

state

The gdk:modifier-type bit-mask representing the state of the modifier keys, for example, the Control, Shift and Alt keys, and the pointer buttons.
