type

The gdk:event-type type of the event, the :touchpad-swipe value.

window

The gdk:window object which received the event.

send-event

True if the event was sent explicitly.

phase

The integer with the current phase of the gesture.

n-fingers

The integer with the number of fingers triggering the swipe.

time

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

x

The double float x coordinate of the pointer.

y

The double float y coordinate of the pointer.

dx

The double float with the movement delta in the x axis of the swipe focal point.

dy

The double float with the movement delta in the y axis of the swipe focal point.

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.

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.
