activate()

virtual void inviwo::CanvasQOpenGLWidget::activate ( )

overridevirtual

Implements inviwo::Canvas.

activeContext()

virtual ContextID inviwo::CanvasQOpenGLWidget::activeContext ( ) const

overridevirtual

Implements inviwo::Canvas.

contextId()

virtual ContextID inviwo::CanvasQOpenGLWidget::contextId ( ) const

overridevirtual

Implements inviwo::Canvas.

createHiddenCanvas()

virtual std::unique_ptr< Canvas > inviwo::CanvasQOpenGLWidget::createHiddenCanvas ( )

overridevirtual

Implements inviwo::Canvas.

getCanvasDimensions()

virtual size2_t inviwo::CanvasQOpenGLWidget::getCanvasDimensions ( ) const

overridevirtual

Implements inviwo::CanvasGL.

glSwapBuffers()

virtual void inviwo::CanvasQOpenGLWidget::glSwapBuffers ( )

overridevirtual

Implements inviwo::CanvasGL.

onContextMenu()

void inviwo::CanvasQOpenGLWidget::onContextMenu

(

std::function< bool(QMenu &, ContextMenuCategories)>

callback

)

Set a callback to be invoked on context menu events. The callback can add more functionality to the context menu. If the function returns true the menu will be shown, else it will be discarded.

propagateEvent()

virtual void inviwo::CanvasQOpenGLWidget::propagateEvent ( Event * e, Outport * source )

overrideprotectedvirtual

Implements inviwo::EventPropagator.

releaseContext()

virtual void inviwo::CanvasQOpenGLWidget::releaseContext ( )

overrideprotectedvirtual

Implements inviwo::Canvas.

render()

virtual void inviwo::CanvasQOpenGLWidget::render ( std::shared_ptr< const Image > image, LayerType layerType = LayerType::Color, size_t idx = 0 )

overridevirtual

Reimplemented from inviwo::CanvasGL.

update()

virtual void inviwo::CanvasQOpenGLWidget::update ( )

overridevirtual

Reimplemented from inviwo::CanvasGL.
