Member Function Documentation

QSize GradientSignal::GradientPreviewWidget::GetPreviewSize ( ) const
overrideprotectedvirtual

Same as above, we need an abstract way to retrieve the size of the actual preview image from the QGraphicsItem

Implements GradientSignal::EditorGradientPreviewRenderer.

void GradientSignal::GradientPreviewWidget::OnUpdate ( )
overrideprotectedvirtual

Since this base class is shared between a QWidget and a QGraphicsItem, we need to abstract the actual update() call so that they can invoke the proper one

Implements GradientSignal::EditorGradientPreviewRenderer.
