Graphics View provides a surface for managing and interacting with a large number of custom-made 2D graphical items, and a view widget for visualizing the items, with support for zooming and rotation. Graphics View provides a surface for managing and interacting with a large number of custom-made 2D graphical items, and a view widget for visualizing the items, with support for zooming and rotation. The framework includes an event propagation architecture that allows precise double-precision. If I only needed the table and form views this would be easy, I'd just use the Qt Model/View framework. However I need the map view to provide functionality only really available using the Graphics View framework, which is essentially it's own Model/View framework with the QGraphicsScene acting as the data model. I can think of two ways to do this.
