[Octave-bug-tracker] [bug #53443] Variable Editor: openvar VAR should show the tab on which the variable editor is

[Mike Miller]

Follow-up Comment #13, bug #53443 (project octave):

For reference, pointers to widgets are pulled out of QVariants elsewhere in
libgui, it would probably be helpful to our future selves if we did it
consistently in all places.

In webinfo.cc:


QVariant tab_data = _tab_bar->tabData (index);
_text_browser = static_cast<QTextBrowser *> (tab_data.value<void*> ());
…
QVariant tab_data = _tab_bar->tabData (index);
QWidget *w = static_cast<QWidget *> (tab_data.value<void*> ());
