QAbstract3DInputHandler — PyQt Documentation v6.9.0 (original) (raw)

PyQt6.QtDataVisualization.QAbstract3DInputHandler

Inherits from QObject.

Description¶

The base class for implementations of input handlers.

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.

Enums¶

InputView

Predefined input views for mouse and touch based input handlers.

Member	Value	Description
InputViewNone	0	Mouse or touch not on a view.
InputViewOnPrimary	1	Mouse or touch input received on the primary view area. If secondary view is displayed when inputView() becomes , secondary view is closed.
InputViewOnSecondary	2	Mouse or touch input received on the secondary view area.

Methods¶

__init__(parent: QObject = None)

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