Detailed Description

QAbstract3DInputHandler is the base class that is subclassed by different input handling implementations that take input events and translate those to camera and light movements. Input handlers also translate raw input events to slicing and selection events in the scene.

class PySide6.QtDataVisualization.QAbstract3DInputHandler([parent=None])

Parameters

parent – PySide6.QtCore.QObject

Constructs the base class. An optional parent parameter can be given and is then passed to QObject constructor.

PySide6.QtDataVisualization.QAbstract3DInputHandler.InputView

Predefined input views for mouse and touch based input handlers.

Constant	Description
QAbstract3DInputHandler.InputViewNone	Mouse or touch not on a view.
QAbstract3DInputHandler.InputViewOnPrimary	Mouse or touch input received on the primary view area. If secondary view is displayed when inputView becomes , secondary view is closed.
QAbstract3DInputHandler.InputViewOnSecondary	Mouse or touch input received on the secondary view area.

PySide6.QtDataVisualization.QAbstract3DInputHandler.inputPosition()

Return type

PySide6.QtCore.QPoint

This property holds The last input position based on the processed input events..

PySide6.QtDataVisualization.QAbstract3DInputHandler.inputView()

Return type

InputView

This property holds The current enumerated input view based on the view of the processed input events..

One of the InputView enum values.

When the view changes, the inputViewChanged signal is emitted.

PySide6.QtDataVisualization.QAbstract3DInputHandler.mouseDoubleClickEvent(event)

Parameters

event – PySide6.QtGui.QMouseEvent

Override this to handle mouse double click events. Mouse double click event is given in the event.

PySide6.QtDataVisualization.QAbstract3DInputHandler.mouseMoveEvent(event, mousePos)

Parameters

• event – PySide6.QtGui.QMouseEvent

• mousePos – PySide6.QtCore.QPoint

Override this to handle mouse move events. Mouse move event is given in the event and the mouse position in mousePos.

PySide6.QtDataVisualization.QAbstract3DInputHandler.mousePressEvent(event, mousePos)

Parameters

• event – PySide6.QtGui.QMouseEvent

• mousePos – PySide6.QtCore.QPoint

Override this to handle mouse press events. Mouse press event is given in the event and the mouse position in mousePos.

PySide6.QtDataVisualization.QAbstract3DInputHandler.mouseReleaseEvent(event, mousePos)

Parameters

• event – PySide6.QtGui.QMouseEvent

• mousePos – PySide6.QtCore.QPoint

Override this to handle mouse release events. Mouse release event is given in the event and the mouse position in mousePos.

PySide6.QtDataVisualization.QAbstract3DInputHandler.positionChanged(position)

Parameters

position – PySide6.QtCore.QPoint

PySide6.QtDataVisualization.QAbstract3DInputHandler.prevDistance()

Return type

int

setPrevDistance()

PySide6.QtDataVisualization.QAbstract3DInputHandler.previousInputPos()

Return type

PySide6.QtCore.QPoint

Returns the previous input position.

setPreviousInputPos()

PySide6.QtDataVisualization.QAbstract3DInputHandler.scene()

Return type

PySide6.QtDataVisualization.Q3DScene

This property holds The 3D scene this abstract input handler is controlling..

One input handler can control one scene. Setting a scene to an input handler does not transfer the ownership of the scene.

Parameters

scene – PySide6.QtDataVisualization.Q3DScene

PySide6.QtDataVisualization.QAbstract3DInputHandler.setInputPosition(position)

Parameters

position – PySide6.QtCore.QPoint

This property holds The last input position based on the processed input events..

PySide6.QtDataVisualization.QAbstract3DInputHandler.setInputView(inputView)

Parameters

inputView – InputView

This property holds The current enumerated input view based on the view of the processed input events..

One of the InputView enum values.

When the view changes, the inputViewChanged signal is emitted.
