Detailed Description#

class PySide6.QtGui.QEventPoint(other)#

PySide6.QtGui.QEventPoint([id=-1[, device=None]])

PySide6.QtGui.QEventPoint(pointId, state, scenePosition, globalPosition)

Parameters:

state – State
scenePosition – PySide6.QtCore.QPointF
globalPosition – PySide6.QtCore.QPointF
other – PySide6.QtGui.QEventPoint
device – PySide6.QtGui.QPointingDevice
id – int
pointId – int

Constructs an event point by making a shallow copy of other.

Constructs an event point with the given pointId, state, scenePosition and globalPosition.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.QtGui.QEventPoint.accepted: bool#

This property holds the accepted state of the event point..

In widget-based applications, this property is not used, as it’s only meaningful for a widget to accept or reject a complete QInputEvent .

In Qt Quick however, it’s normal for an Item or Event Handler to accept only the individual points in a QTouchEvent that are actually participating in a gesture, while other points can be delivered to other items or handlers. For the sake of consistency, that applies to any QPointerEvent ; and delivery is done only when all points in a QPointerEvent have been accepted.

Access functions:

isAccepted ()
setAccepted ([accepted=true])

property PᅟySide6.QtGui.QEventPoint.device: PySide6.QtGui.QPointingDevice#

This property holds the pointing device from which this event point originates..

Access functions:

device ()

property PᅟySide6.QtGui.QEventPoint.ellipseDiameters: PySide6.QtCore.QSizeF#

This property holds the width and height of the bounding ellipse of the touch point..

The return value is in logical pixels. Most touchscreens do not detect the shape of the contact point, and no mice or tablet devices can detect it, so a null size is the most common value. On some touchscreens the diameters may be nonzero and always equal (the ellipse is approximated as a circle).

Access functions:

ellipseDiameters ()

property PᅟySide6.QtGui.QEventPoint.globalGrabPosition: PySide6.QtCore.QPointF#

This property holds the global position at which this point was grabbed..

The global position is relative to the screen or virtual desktop.

property PᅟySide6.QtGui.QEventPoint.globalLastPosition: PySide6.QtCore.QPointF#

This property holds the global position of this point from the previous press or move event..

property PᅟySide6.QtGui.QEventPoint.grabPosition: PySide6.QtCore.QPointF#

This property holds the position at which this point was grabbed..

The position is relative to the widget or item that received the event.

position

Access functions:

grabPosition ()

property PᅟySide6.QtGui.QEventPoint.id: int#

This property holds the ID number of this event point..

Note

Do not assume that ID numbers start at zero or that they are sequential. Such an assumption is often false due to the way the underlying drivers work.

Access functions:

id ()

property PᅟySide6.QtGui.QEventPoint.lastPosition: PySide6.QtCore.QPointF#

This property holds the position of this point from the previous press or move event..

The position is relative to the widget or item that received the event.

property PᅟySide6.QtGui.QEventPoint.lastTimestamp: int#

This property holds the time from the previous QPointerEvent that contained this point..

property PᅟySide6.QtGui.QEventPoint.pressure: float#

This property holds the pressure of this point..

The return value is in the range 0.0 to 1.0.

Access functions:

pressure ()

property PᅟySide6.QtGui.QEventPoint.rotation: float#

This property holds the angular orientation of this point..

The return value is in degrees, where zero (the default) indicates the finger, token or stylus is pointing upwards, a negative angle means it’s rotated to the left, and a positive angle means it’s rotated to the right. Most touchscreens do not detect rotation, so zero is the most common value.

Access functions:

rotation ()

property PᅟySide6.QtGui.QEventPoint.sceneGrabPosition: PySide6.QtCore.QPointF#

This property holds the scene position at which this point was grabbed..

The scene position is the position relative to QQuickWindow if handled in QQuickItem::event(), in QGraphicsScene coordinates if handled by an override of QGraphicsItem::touchEvent(), or the window position in widget applications.

Access functions:

timestamp ()

property PᅟySide6.QtGui.QEventPoint.uniqueId: PySide6.QtGui.QPointingDeviceUniqueId#

This property holds the unique ID of this point or token, if any..

It is often invalid (see isValid() ), because touchscreens cannot uniquely identify fingers.

When it comes from a QTabletEvent , it identifies the serial number of the stylus in use.

It may identify a specific token (fiducial object) when the TUIO driver is in use with a touchscreen that supports them.

Access functions:

uniqueId ()

property PᅟySide6.QtGui.QEventPoint.velocity: PySide6.QtGui.QVector2D#

This property holds a velocity vector, in units of pixels per second, in the coordinate. system of the screen or desktop..

Note

If the device’s capabilities include Velocity , it means velocity comes from the operating system (perhaps the touch hardware or driver provides it). But usually the Velocity capability is not set, indicating that the velocity is calculated by Qt, using a simple Kalman filter to provide a smoothed average velocity rather than an instantaneous value. Effectively it tells how fast and in what direction the user has been dragging this point over the last few events, with the most recent event having the strongest influence.

Constant	Description
QEventPoint.Unknown	Unknown state.
QEventPoint.Stationary	The event point did not move.
QEventPoint.Pressed	The touch point or button is pressed.
QEventPoint.Updated	The event point was updated.
QEventPoint.Released	The touch point or button was released.
