ProjectionsEditorCanvas Class Reference

Description

Holds a graphics scene to draw projections on top of ColorMap. Being a part of ProjectionEditor, provides interaction logic between graphics scene and ProjectionsWidget.

Particularly, it creates temporary ProjectionItem in projection container, when mouse is inside ColorMap viewport.
