Always show second line in QToolbar

Actual Behaviour

I ordered my toolbars in the top area in two lines, something like

MyMainWindow::init()
{
    addToolBar(Qt::TopToolBarArea, m_toolbar_1);
    addToolBar(Qt::TopToolBarArea, m_toolbar_2);

    addToolBarBreak(Qt::TopToolBarArea);

    addToolBar(Qt::TopToolBarArea, m_toolbar_3);
    addToolBar(Qt::TopToolBarArea, m_toolbar_4);
    addToolBar(Qt::TopToolBarArea, m_toolbar_5);
}

leading to a results similar to this example using Qt Designer. As you can see the top tool bars are layed out in two lines. Toolbars are layed out over two lines

Now it is very common that the toolbars in the second line (that is m_toolbar_3, m_toolbar_4 and m_toolbar_5) get hidden. This causes the whole second line to disappear, as can be seen in the following screenshot. enter image description here

Desired Behaviour

I want the second toolbar line to be always shown, no matter if there are visible toolbars in it or not.

This is to avoid visual noise of constantly appearing/disappearing tool bars. The visual noise is especially recognisable in the central widget (where "Form ..." is placed), which is either moved up or down.

Is there a way to do that?

If it is ok that toolbars stay on the same spot no matter what you could simply set them to non-movable. QToolBar::setMovable to false.

This may not be the best solution ever, but it should work.

QToolBar has a visibilityChanged signal.

You could connect that to a slot, for example :

connect(m_toolbar, SIGNAL(visibilityChanged(bool)), this, SLOT(onVisibilityChanged(bool)))

Where :

onVisibilityChanged(bool visible)
{
    if(false == visible)
    {
        m_toolbar.setVisible(true);
    }
}
