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 &)>

callback

)

Set a callback to be invoded on contextmeny events. The callback can add more functionallity to the context menu. I the function retuns true the menu will be shown, else it will be discarded.

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.
