GraphicsView in Qt Creator

[ProTonS]

Hi guys.

I have problem here.

I am using qt designer to create my Gui. I put a GraphicsView in the center of my QMainWindow and I´ve tried to change the background but I cant, all the box is still white. What is my mistake?

QGraphicsScene scene;
scene.setBackgroundBrush(Qt::blue);
ui.graphicsView->setScene(&scene);
ui.graphicsView->show();

QGraphicsScene scene;
scene.setBackgroundBrush(Qt::blue);
ui.graphicsView->setScene(&scene);
ui.graphicsView->show();

To copy to clipboard, switch view to plain text mode 

Thanks in advanced

Jorge

You have created the scene on the stack so it gets destroyed after running out of scope.

Now it works!

Thanks a lot, wysota.
