Detailed Description#

class PySide6.QtGui.QEventPoint(other)#

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

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

Parameters

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

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

PySide6.QtGui.QEventPoint.State#

Specifies the state of this event point.

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.

PySide6.QtGui.QEventPoint.device()#
Return type

PySide6.QtGui.QPointingDevice

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

PySide6.QtGui.QEventPoint.ellipseDiameters()#
Return type

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).

PySide6.QtGui.QEventPoint.globalGrabPosition()#
Return type

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.

PySide6.QtGui.QEventPoint.globalLastPosition()#
Return type

PySide6.QtCore.QPointF

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

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

PySide6.QtGui.QEventPoint.globalPosition()#
Return type

PySide6.QtCore.QPointF

This property holds the global position of this point..

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

PySide6.QtGui.QEventPoint.globalPressPosition()#
Return type

PySide6.QtCore.QPointF

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

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

PySide6.QtGui.QEventPoint.grabPosition()#
Return type

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.

PySide6.QtGui.QEventPoint.id()#
Return type

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.

PySide6.QtGui.QEventPoint.isAccepted()#
Return type

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.

PySide6.QtGui.QEventPoint.lastNormalizedPos()#
Return type

PySide6.QtCore.QPointF

Note

This function is deprecated.

Use globalLastPosition() instead.

Returns the normalized position of this point from the previous press or move event.

The coordinates are normalized to availableVirtualGeometry() , i.e. (0, 0) is the top-left corner and (1, 1) is the bottom-right corner.

PySide6.QtGui.QEventPoint.lastPos()#

PySide6.QtCore.QPointF

Note

This function is deprecated.

Return type

PySide6.QtCore.QPointF

Note

This function is deprecated.

PySide6.QtGui.QEventPoint.lastScreenPos()#
Return type

Note

This function is deprecated.

PySide6.QtGui.QEventPoint.lastTimestamp()#
Return type

ulong

PySide6.QtGui.QEventPoint.normalizedPos()#
Return type

PySide6.QtGui.QEventPoint.normalizedPosition()#
Return type

PySide6.QtCore.QPointF

Returns the normalized position of this point.

The coordinates are calculated by transforming globalPosition() into the space of availableVirtualGeometry() , i.e. (0, 0) is the top-left corner and (1, 1) is the bottom-right corner.

PySide6.QtGui.QEventPoint.__ne__(other)#
Parameters

bool

Returns true if this event point is not equal to other, otherwise return false.

PySide6.QtGui.QEventPoint.__eq__(other)#
Parameters

otherPySide6.QtGui.QEventPoint

Return type

bool

Returns true if this event point is equal to other, otherwise return false.

PySide6.QtGui.QEventPoint.pos()#
Return type

PySide6.QtCore.QPointF

Note

This function is deprecated.

Use position() instead.

Returns the position of this point, relative to the widget or item that received the event.

PySide6.QtGui.QEventPoint.position()#
Return type

PySide6.QtCore.QPointF

This property holds the position of this point..

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

PySide6.QtGui.QEventPoint.pressPosition()#
Return type

PySide6.QtCore.QPointF

PySide6.QtGui.QEventPoint.pressTimestamp()#
Return type

ulong

This property holds the most recent time at which this point was pressed..

timestamp

PySide6.QtGui.QEventPoint.pressure()#
Return type

float

This property holds the pressure of this point..

The return value is in the range 0.0 to 1.0.

PySide6.QtGui.QEventPoint.rotation()#
Return type

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.

PySide6.QtGui.QEventPoint.sceneGrabPosition()#
Return type

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 event() , in QGraphicsScene coordinates if handled by an override of QGraphicsItem::touchEvent(), or the window position in widget applications.

PySide6.QtGui.QEventPoint.sceneLastPosition()#
Return type

PySide6.QtCore.QPointF

PySide6.QtGui.QEventPoint.setAccepted([accepted=true])#
Parameters

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.

Parameters

otherPySide6.QtGui.QEventPoint

PySide6.QtGui.QEventPoint.timeHeld()#

timestamp()

PySide6.QtGui.QEventPoint.uniqueId()#
Return type

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.

PySide6.QtGui.QEventPoint.velocity()#
Return type

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.
