Changing AlwaysOnTop window flag

[bpetty]

Hey guys. I have this app that the user can choose if he/she wants it always on top or not via a menu option. This is a chackable menu action that toggles the following method:

void MainForm::menuAlwaysOnTop(bool bEnable)
{
    if (bEnable == true)
    {
        // This line is hiding my window :(
        setWindowFlags(windowFlags() | Qt::WindowStaysOnTopHint);
    }
    else
    {
        // remove Qt::WindowStaysOnTopHint
    }
}

void MainForm::menuAlwaysOnTop(bool bEnable)
{
    if (bEnable == true)
    {
        // This line is hiding my window :(
        setWindowFlags(windowFlags() | Qt::WindowStaysOnTopHint);
    }
    else
    {
        // remove Qt::WindowStaysOnTopHint
    }
}

My MainForm class derives from QMainWindow. The problem I am having is that when this method runs... my window disappears! Augh. I can't explain why. Does anyone have an idea of what I can do to fix this?
