Detailed Description

3D VTK widget for a QWidget

This 3D widget handles events between VTK and Qt for a QWidget placed in a scene. It currently takes 6dof events as from VR controllers and if they intersect the widghet it converts them to Qt events and fires them off.

Standard vtkObject methods.

Reimplemented from vtkObject.

◆ SetRepresentation()

void vtkQWidgetWidget::SetRepresentation ( vtkQWidgetRepresentation * rep )

Specify an instance of vtkQWidgetRepresentation used to represent this widget in the scene.

Note that the representation is a subclass of vtkProp so it can be added to the renderer independent of the widget.

◆ SetEnabled()

void vtkQWidgetWidget::SetEnabled ( int )

overridevirtual

Methods for turning the interactor observer on and off, and determining its state.

All subclasses must provide the SetEnabled() method. Enabling a vtkInteractorObserver has the side effect of adding observers; disabling it removes the observers. Prior to enabling the vtkInteractorObserver you must set the render window interactor (via SetInteractor()). Initial value is 0.

Reimplemented from vtkInteractorObserver.

◆ GetQWidgetRepresentation()

vtkQWidgetRepresentation * vtkQWidgetWidget::GetQWidgetRepresentation ( )

Return the representation as a vtkQWidgetRepresentation.

◆ CreateDefaultRepresentation()

void vtkQWidgetWidget::CreateDefaultRepresentation ( )

overridevirtual

Create the default widget representation if one is not set.

Implements vtkAbstractWidget.

◆ SetWidget()

void vtkQWidgetWidget::SetWidget ( QWidget * w )

Set the QWidget that will receive the events.
