[Octave-patch-tracker] [patch #7990] Add builtin Qt equivalents of UI dialogs, i.e., , qterrordlg, qtinputdlg, etc.

[Dan Sebald]

Follow-up Comment #4, patch #7990 (project octave):

Or, better still, overload is_gui_running as follows:

int is_gui_running (void);
std::string is_gui_running (std::string);

where the latter works as follows:

std:string f = is_gui_running ("errordlg");

returns "qterrordlg" (or "gtkerrordlg") if the GUI is running, "" otherwise.

Then one could simplify to

if (is_gui_running ())
  eval(is_gui_running ("errordlg"))
end
