gdk-event, common-lisp:structure-object, common-lisp:t

None

Used for touch events. The type field will be one of the :touch-begin, :touch-update, :touch-end or :touch-cancel values.

Touch events are grouped into sequences by means of the sequence field, which can also be obtained with the gdk-event-event-sequence function. Each sequence begins with a :touch-begin event, followed by any number of :touch-update events, and ends with a :touch-end event or :touch-cancel event. With multitouch devices, there may be several active sequences at the same time.

type

The gdk-event-type type of the event, one of the values :touch-begin, :touch-update, :touch-end, :touch-cancel.

window

The gdk-window object which received the event.

send-event

True if the event was sent explicitly.

time

An 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.

axes

The x, y fields translated to the axes of the device.

state

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

sequence

The gdk-event-sequence event sequence that the event belongs to.

emulating-pointer

Whether the event should be used for emulating pointer event.

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.
