    hmm. it does sounds like a focus problem on initial show.

    You could try to create it visible and then override
    showEvent for mainwindow
    and there hide it.
    ( so when mainwin shows, it is still hidden)

          QGroupBox must steal first click to focus.

          What widgets do u put in this QGroupBox ?

            @mrjj They are slightly modified QFrames or QLabels, the modification being to add the 'clicked' signal to the original. But setting the focus to the QGroupBox had no effect on the problem.

              Hmm I tried with
              https://wiki.qt.io/Clickable_QLabel
              Which sounds like what you have but
              show/hiding the QGroupBox did not eat first click.

              I think we need a fellow Python user to find this :)
              seems not to happen in c++- well not in my sample anyway.

                @mrjj I have found that, once the menu is displayed, if I click in the main window before clicking in the menu then the click on the menu is accepted. Unfortunately I don't have enough experience of Python to know where to go next, I'll keep trying odds and sods in the meantime.

                    @mrjj Using focusChanged I have determined that, when the mouse clicks on the menubar the focus is given to the menubar object, as expected and the QGroupBox is displayed. If I do not deliberately setFocus to the QGroupBox then the first click in the QGroupBox removes the focus from the menubar to None. Subsequent clicks in the QGroupBox set the focus to the menubar, the click is processed and the focus goes back to None. If I deliberately setFocus to the QGroupBox then focus transfers to the QGroupBox, then the first click in the QGroupBox removes the focus from the QGroupBox but is not processed. Subsequent clicks in the QGroupBox set the focus to the QGroupBox, the click is processed and the focus goes back to None!

                      Sidestepped the problem by substituting a toolbar for the menubar!

                        good workaround.
