[Octave-bug-tracker] [bug #44282] 'gui_mainfcn' undefined

[Guillaume]

Follow-up Comment #4, bug #44282 (project octave):

Using the example files from bug #57212 and another one of my own, here is an
attempt at implementing gui_mainfcn.m:


function varargout = gui_mainfcn (gui_State, varargin)
  if (nargin == 1 || isempty (gui_State.gui_Callback))
    filename = file_in_loadpath ([gui_State.gui_Name ".fig"]);
    copies = ifelse (gui_State.gui_Singleton, "reuse", "new");
    H = openfig (filename, copies, "invisible");
    for i = 1:2:numel (varargin)
      try
        set (H, varargin{i}, varargin{i+1});
      catch
        break;
      end_try_catch
    endfor
    handles = guihandles (H);
    guidata (H, handles);
    feval (gui_State.gui_OpeningFcn, H, [], handles, varargin{:});
    set (H, "Visible", "on");
    handles = guidata (H);
    varargout{1} = feval (gui_State.gui_OutputFcn, H, [], handles);
  else
    [varargout{1:nargout}] = feval (gui_State.gui_Callback, varargin{2:end});
  endif
endfunction


I think it is already usable in many situations. Issues I am aware of are:

* gui_LayoutFcn is not implemented.
* if the GUIDE-generated function is called with ('Visible','off'), it will
not be used.
* unclear whether getappdata should be used (and where/how?).

Is there any chance this could be added to Octave 6 even if partially
incomplete? Getting more feedbacks would allow to figure out the missing bits.
