Detailed Description¶
The
QGestureEvent
class contains a list of gestures, which can be obtained using thegestures()
function.The gestures are either active or canceled. A list of those that are currently being executed can be obtained using the
activeGestures()
function. A list of those which were previously active and have been canceled can be accessed using thecanceledGestures()
function. A gesture might be canceled if the current window loses focus, for example, or because of a timeout, or for other reasons.If the event handler does not accept the event by calling the generic
accept()
function, all individualQGesture
object that were not accepted and in theGestureStarted
state will be propagated up the parent widget chain until a widget accepts them individually, by callingaccept()
for each of them, or an event filter consumes the event.

(arg__1)¶ - Parameters
arg__1 –
QGesture
Sets the accept flag of the given
gesture
object, the equivalent of callingsetAccepted(gesture, true)
.Setting the accept flag indicates that the event receiver wants the gesture. Unwanted gestures may be propagated to the parent widget.

(arg__1) - Parameters
arg__1 –
GestureType
Sets the accept flag of the given
gestureType
, the equivalent of callingsetAccepted(gestureType, true)
.Setting the accept flag indicates that the event receiver wants the gesture. Unwanted gestures may be propagated to the parent widget.

gesture
(type)¶ - Parameters
type –
GestureType
- Return type
Returns a gesture object by
type
.

gestures
()¶ - Return type
Returns all gestures that are delivered in the event.

ignore
(arg__1)¶ - Parameters
arg__1 –
QGesture
Clears the accept flag parameter of the given
gesture
object, the equivalent of callingsetAccepted(gesture, false)
.Clearing the accept flag indicates that the event receiver does not want the gesture. Unwanted gestures may be propagated to the parent widget.

isAccepted
(arg__1)¶ - Parameters
arg__1 –
GestureType
- Return type
bool
Returns
true
if the gesture of typegestureType
is accepted; otherwise returnsfalse
.
-
PySide2.QtWidgets.QGestureEvent.
isAccepted
(arg__1) - Parameters
arg__1 –
QGesture
- Return type
bool
Returns
true
if thegesture
is accepted; otherwise returnsfalse

mapToGraphicsScene
(gesturePoint)¶ - Parameters
gesturePoint –
QPointF
- Return type
QPointF
Returns the scene-local coordinates if the
gesturePoint
is inside a graphics view.This functional might be useful when the gesture event is delivered to a
QGraphicsObject
to translate a point in screen coordinates to scene-local coordinates.See also

setAccepted
(arg__1, arg__2)¶ - Parameters
arg__1 –
QGesture
arg__2 –
bool
Sets the accept flag of the given
gesture
object to the specifiedvalue
.Setting the accept flag indicates that the event receiver wants the
gesture

Gesture
are accepted, and gestures inGestureOverride
events are ignored.For convenience, the accept flag can also be set with
accept(gesture)
, and cleared withignore(gesture)
