Resize Widget To Desktop Size

[fruzzo]

For me it works with Qt 4 without any additional tricks:

#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QWidget window;
    window.showMaximized();
    return app.exec();
}

#include <QtGui>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QWidget window;
    window.showMaximized();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

I know...I try some examples like your code and they works fine.
However I'm working with Qt3.3.5 and window is a QMainWindow not a QWidget.
I want remove the resize because I've some problmes with it...so any idea how to resolve the question?

In that case it is highly probable that the bug is on your side. It's just hidden somewhere in a big and complex project. That's why it's always a good idea to put up together a minimal compilable test application reproducing the problem.

Actually, QMainWindow IS A QWidget. And QWidget::showFullScreen() functionality is implemented in QWidget code. I doubt you can reproduce the problem with a plain QMainWindow either. If you can reproduce it with a QMainWindow subclass, then the problem might be in that subclass.

How can I catch the signal emitted when launch mw->showMaximized()? And a way to know when resize (after showMaximized()) is completed?
