[Qt-interest] Toggle visibility of a QMainWindow's menu bar?

[Andreas Diehl]

Oh sorry, that was a mistake. I forgot to change the topic name. Damn 
copy&paste ...

But to your problem with the QMenubar I can tell you, that I've tested it 
(with Qt 4.4.2) and menuBar()->hide() worked as well as menuBar()->show().
I tried it wihtin my QMainWindow class itself using
    this->menuBar()->hide();
so perhaps it doesn't work from outside or your window doesn't have any 
menubar at the point you want to hide it?
Perhaps check how you create your menubar. My example code is:

public class MyWindow extends QMainWindow
{
    public MyWindow()
    {
        super();
        buildLayout();
        buildActions();
        buildMenu();
    }

    ...

    private void buildMenu()
    {
        QMenu fileMenu = this.menuBar().addMenu("File");
        fileMenu.addAction( loadAction);
        //and so on
    }

    protected void slotHideMenubar()
    {
        this.menuBar().hide();
    }

    protected void slotShowMenubar()
    {
        this.menuBar().show();
    }
}

I know it's Java code, but C++ should look very similar. Note that I don't 
use any newly created QMenuBar.
