[Octave-bug-tracker] [bug #53429] Unnecessary underlining of text in selected line of Command History

[Dan Sebald]

Follow-up Comment #2, bug #53429 (project octave):

I've looked at both history-dock-widget.cc and file-dock-widget.cc and I don't
see in either case that anything special is done to affect the highlighting. 
It creates a selector model and pretty much uses the default settings.

However, I think what is unique to history-dock-widget.cc is that it has that
extra layer of a Filter [x].  That is, the history list is passed through a
filter first (and even if the Filter is not selected, I think the list goes
through the filter).  That filter appears to have an extra "lineEdit"


    if (m_history_list_view->hasFocus ())
      handle_contextmenu_copy (true);
    if (m_filter->lineEdit ()->hasFocus ()
        && m_filter->lineEdit ()->hasSelectedText ())
      {
        QClipboard *clipboard = QApplication::clipboard ();
        clipboard->setText (m_filter->lineEdit ()->selectedText ());
      }


My initial guess would be that the lineEdit() has some properties which
include underlining.  This would be something beyond the selector-model's
highlighting.  Probably need to find some way of controlling the lineEdit
"underline when highlight".
