Graphics view

QGraphicsView, QGraphicScene and QGraphicsItem provide a way for applications based on Qt Widgets to show 2D graphics.

The source code can be found on the Git repository under the Chapter01-graphicsview directory, in the cp1 branch.

Every QGraphicsView needs a QGraphicsScene. Every QGraphicsScene needs one or more QGraphicsItem.

QGraphicsItem can be any of the following: 

• QGraphicsEllipseItem
• QGraphicsLineItem
• QGraphicsLineItem
• QGraphicsPathItem
• QGraphicsPixmapItem
• QGraphicsPolygonItem
• QGraphicsRectItem
• QGraphicsSimpleTextItem
• QGraphicsTextItem

Qt Designer has support for adding QGraphicsView . You can follow these steps to do so:

1. Drag the QGraphicsView to a new application form and fill the form with a QGridLayout like we did before.

2. Implement a QGraphicsScene in the source code and add it to the QGraphicsView
