Class Details¶

class Gtk.GestureSwipe(**kwargs)¶

Bases:	`Gtk.GestureSingle`
Abstract:	No
Structure:	`Gtk.GestureSwipeClass`

Gtk.GestureSwipe is a Gtk.Gesture implementation able to recognize swipes, after a press/move/…/move/release sequence happens, the Gtk.GestureSwipe ::swipe signal will be emitted, providing the velocity and directionality of the sequence at the time it was lifted.

If the velocity is desired in intermediate points, Gtk.GestureSwipe.get_velocity() can be called on eg. a Gtk.Gesture ::update handler.

All velocities are reported in pixels/sec units.

classmethod new(widget)[source]¶

Parameters:	widget (`Gtk.Widget`) – a `Gtk.Widget`
Returns:	a newly created `Gtk.GestureSwipe`
Return type:	`Gtk.Gesture`

Returns a newly created Gtk.Gesture that recognizes swipes.

New in version 3.14.

get_velocity()[source]¶

Returns:

whether velocity could be calculated

velocity_x:	return value for the velocity in the X axis, in pixels/sec
velocity_y:	return value for the velocity in the Y axis, in pixels/sec

Return type: (bool, velocity_x: float, velocity_y: float)

If the gesture is recognized, this function returns True and fill in velocity_x and velocity_y with the recorded velocity, as per the last event(s) processed.

New in version 3.14.

Signal Details¶

Gtk.GestureSwipe.signals.swipe(gesture_swipe, velocity_x, velocity_y)¶

Signal Name:	`swipe`
Flags:	`RUN_LAST`
Parameters:	gesture_swipe (`Gtk.GestureSwipe`) – The object which received the signal velocity_x (`float`) – velocity in the X axis, in pixels/sec velocity_y (`float`) – velocity in the Y axis, in pixels/sec

This signal is emitted when the recognized gesture is finished, velocity and direction are a product of previously recorded events.

New in version 3.14.
