type

The gdk:event-type type of the scroll event.

window

The gdk:window object which received the event.

send-event

True if the event was sent explicitly.

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.

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.

direction

The gdk:scroll-direction direction to scroll to, one of the :up, :down, :left, :right or :smooth values.

device

The gdk:device object where the event originated.

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.

delta-x

The double float x coordinate of the scroll delta.

delta-y

The double float y coordinate of the scroll delta.
