Resize QGraphicsItem when window resizes

[guidupas]

First of all, thank you for the help.

I am using the QGraphicsView inside a QGridLayout and it resizes fine. My problem is that I need to resize the itens inside a QGraphicsScene that is inside the view. I need the itens resizing when the view is resized. Could you help me in this?

Implement resizeEvent() for the widget that holds the QGraphicsView. Maybe this is the MainWindow of your class. In that event handler, retrieve the QRect of the QGraphicsView (not the QRect passed in the event - that's the rect for the entire main window), then call QGraphicsView::fitInView() with that QRect. If you want the objects in the view to stretch the same in both directions (squares remain square, circles remain circular), then use the Qt::AspectRatioMode value Qt::KeepAspectRatio, otherwise it will stretch differently in horizontal vs. vertical dimensions - squares will become rectangles, circles will become ellipses, etc.
