[Octave-bug-tracker] [bug #53410] Variable Editor: Title bar doesn't highlight according to focus rules

[Dan Sebald]

Follow-up Comment #14, bug #53410 (project octave):

Huh.  So it does.  I printed out the following:


  void variable_editor::focusInEvent (QFocusEvent *ev)
  {
std::cerr << "HOCUS FOCUS\n";
    octave_dock_widget::focusInEvent (ev);

    // set focus to the current variable
    QWidget *fw = m_main->focusWidget ();
    if (fw != nullptr)
      fw->setFocus ();
else
std::cerr << "fw is NULL\n";
  }


and it appears that the focusInEvent is occurring with the transition to/from
docked state (good), but the m_main QMainWindow for the individual variables
is losing its focusWidget() (it becomes NULL, bad).  I wonder why, and I
wonder if there is anything one can do to prevent the loss of focusWidget(). 
I would have to think losing focus transitioning to/from docked state must
have always been there but I never paid close attention.

Well, give the following patch a try.  It records the V.E.'s QMainWindow's
focusWidget() just before, presumably, transition to from docked state via the
focusOutEvent().
