QMainWindow::showMaximized() Doesn't Update Size

I'm trying to create a QMainWindow to encapsulate a QGraphicsView that I'm putting in it. I want it to start out maximized, so I do this:

QMainWindow *mainWindow = new QMainWindow();
mainWindow->setWindowState(Qt::WindowMaximized);
mainWindow->show();
qDebug() << mainWindow->size();

Which says my maximized window is 200x100, which is obviously incorrect.

Am I missing some sort of update function? I don't get why it wouldn't update the size. I've also tried using showMaximized() with the same result.

EDIT

My end-goal is to use the QMainWindow as a container for a QGraphicsView containing a QGraphicsScene. On top of all this, I want to have a QWebView at 50% width and 100% height, centered over everything.

So, I need the width and height in order to get all the coordinates and sizes correct.

Well, the effect of setWindowState() is not immediate, it gets executed asynchronously. When the window state changes, the widget receives a changeEvent(), so you should reimplement this or resizeEvent() to get the width() and height() after the maximization takes place.
