Adding QGraphicsView to QVBoxLayout

[awseward1]

Hello,
I've got an application in which I'm trying to display something in a graphics view on a button click in a mainwindow.cpp file.
I've looked at several examples, and many of them seem to be doing such with using something along the lines of

layout->addWidget( view );

where layout is a defined QVBoxLayout, or QHBoxLayout, and view is a QGraphicsView they've defined.
This is definitely not working for me, and I have no idea why.
Any help would be greatly appreciated.

What are you doing with the layout after adding QGraphicsView ? You need to set it on a widget:

QLayout * layout = new QVBoxLayout();
QGraphicsView * view = new QGraphicsView();
layout->addWidget(view);
QWidget * w = new QWidget();
w->setLayout(layout);
w->show();

QLayout * layout = new QVBoxLayout();
QGraphicsView * view = new QGraphicsView();
layout->addWidget(view);
QWidget * w = new QWidget();
w->setLayout(layout);
w->show();

To copy to clipboard, switch view to plain text mode

This completely solved my problem.
Thanks a lot!
