Detailed Description

Container for a GraphGraphicsView containing gates, nets, and modules.

The GraphicsScene is the scene where the GraphicsItems of the gates, nets and modules are placed in by the layouter. Besides the functions that are provided by its parent class QGraphicScene, it offers functions to work on a grid, to support drag-and-drop on the grid, to access the contained GraphicItems and to handle certain events like changed selections and groupings.
