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 QEvent::accept() function, all individual
QGesture
object that were not accepted and in the Qt::GestureStarted 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.Further Reading¶

- __init__(gestures)¶
- Parameters:
gestures – .list of QGesture
Creates new
QGestureEvent
containing a list ofgestures
.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.
See also
- accept(gestureType)
- Parameters:
gestureType –
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.
See also
Returns a list of active (not canceled) gestures.
Returns a list of canceled gestures.
- gesture(type)¶
- Parameters:
type –
GestureType
- Return type:
Returns a gesture object by
type
.Returns all gestures that are delivered in the event.
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.
See also
- ignore(gestureType)
- Parameters:
gestureType –
GestureType
Clears the accept flag parameter of the given
gestureType
, 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.
See also
Returns
true
if thegesture
is accepted; otherwise returnsfalse
.- isAccepted(gestureType)
- Parameters:
gestureType –
GestureType
- Return type:
bool
Returns
true
if the gesture of typegestureType
is accepted; otherwise returnsfalse
.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
Sets the accept flag of the given
gesture
object to the specifiedvalue
.Setting the accept flag indicates that the event receiver wants the
gesture
. Unwanted gestures may be propagated to the parent widget.By default, gestures in events of type QEvent::Gesture are accepted, and gestures in QEvent::GestureOverride events are ignored.
For convenience, the accept flag can also be set with
accept(gesture)
, and cleared withignore(gesture)
.See also
- setAccepted(gestureType, value)
- Parameters:
gestureType –
GestureType
value – bool
Sets the accept flag of the given
gestureType
object to the specifiedvalue
.Setting the accept flag indicates that the event receiver wants to receive gestures of the specified type,
gestureType
. Unwanted gestures may be propagated to the parent widget.By default, gestures in events of type QEvent::Gesture are accepted, and gestures in QEvent::GestureOverride events are ignored.
For convenience, the accept flag can also be set with
accept(gestureType)
, and cleared withignore(gestureType)
.Returns the widget on which the event occurred.
