Detailed Description#

Q3DInputHandler is the basic input handler for wheel mouse type of input devices.

Default input handler has the following functionalty:

Mouse action

Action

Drag with right button pressed

Rotate graph within limits set for Q3DCamera .

Left click

Select item under cursor or remove selection if none. May open the secondary view depending on the selection mode .

Mouse wheel

Zoom in/out within the allowable zoom range set for Q3DCamera .

Left click on the primary view when the secondary view is visible

Closes the secondary view.

Note

Secondary view is available only for Q3DBars and Q3DSurface graphs.

Mouse action	Action
Drag with right button pressed	Rotate graph within limits set for `Q3DCamera` .
Left click	Select item under cursor or remove selection if none. May open the secondary view depending on the `selection mode` .
Mouse wheel	Zoom in/out within the allowable zoom range set for `Q3DCamera` .
Left click on the primary view when the secondary view is visible	Closes the secondary view. Note Secondary view is available only for `Q3DBars` and `Q3DSurface` graphs.

Rotation, zoom, and selection can each be individually disabled using corresponding properties of this class.

class PySide6.QtDataVisualization.Q3DInputHandler([parent=None])#
