Resizing pixmaps inside QGraphicsScene when the scene is resized

Hi there! I have a window which looks like this : http://imgur.com/tjhpyOX What I want to do is a Game of 15 – I have to put multiple images in a grid inside this QGraphicsScene but the thing is, I want them to resize when I resize this window. The widgets inside the window resize automatically as they’re inside a QGridLayout but I cant get the images inside the QGraphicsScene to resize. How do I do that? Thanks in advance!
