    How do I use jhandles? (or other octave GUI packages)

    Hi,

    I'm trying to make matlab GUIs run in octave.

    I currently have octave installed on Windows with jhandles. I'm supposing the usage of jhandles is the same in Windows as under GNU/Linux.

    Here's the test code I'm using (official MATLAB example):
    simple_gui2.m
    Code:
    function simple_gui2
    % SIMPLE_GUI2 Select a data set from the pop-up menu, then
    % click one of the plot-type push buttons. Clicking the button
    % plots the selected data in the axes.
     
       %  Create and then hide the GUI as it is being constructed.
       f = figure('Visible','off','Position',[360,500,450,285]);
     
       %  Construct the components.
       hsurf = uicontrol('Style','pushbutton','String','Surf',...
              'Position',[315,220,70,25],...
              'Callback',{@surfbutton_Callback});
       hmesh = uicontrol('Style','pushbutton','String','Mesh',...
              'Position',[315,180,70,25],...
              'Callback',{@meshbutton_Callback});
       hcontour = uicontrol('Style','pushbutton',...
              'String','Countour',...
              'Position',[315,135,70,25],...
              'Callback',{@contourbutton_Callback}); 
       htext = uicontrol('Style','text','String','Select Data',...
              'Position',[325,90,60,15]);
       hpopup = uicontrol('Style','popupmenu',...
              'String',{'Peaks','Membrane','Sinc'},...
              'Position',[300,50,100,25],...
              'Callback',{@popup_menu_Callback});
       ha = axes('Units','Pixels','Position',[50,60,200,185]); 
       align([hsurf,hmesh,hcontour,htext,hpopup],'Center','None');
       
       % Create the data to plot.
       peaks_data = peaks(35);
       membrane_data = membrane;
       [x,y] = meshgrid(-8:.5:8);
       r = sqrt(x.^2+y.^2) + eps;
       sinc_data = sin(r)./r;
       
       % Initialize the GUI.
       % Change units to normalized so components resize 
       % automatically.
       set([f,ha,hsurf,hmesh,hcontour,htext,hpopup],...
       'Units','normalized');
       %Create a plot in the axes.
       current_data = peaks_data;
       surf(current_data);
       % Assign the GUI a name to appear in the window title.
       set(f,'Name','Simple GUI')
       % Move the GUI to the center of the screen.
       movegui(f,'center')
       % Make the GUI visible.
       set(f,'Visible','on');
     
       %  Callbacks for simple_gui2. These callbacks automatically
       %  have access to component handles and initialized data 
       %  because they are nested at a lower level.
     
       %  Pop-up menu callback. Read the pop-up menu Value property
       %  to determine which item is currently displayed and make it
       %  the current data.
          function popup_menu_Callback(source,eventdata) 
             % Determine the selected data set.
             str = get(source, 'String');
             val = get(source,'Value');
             disp(str);
             disp(val);
             % Set current data to the selected data set.
             switch str{val};
             case 'Peaks' % User selects Peaks.
                current_data = peaks_data;
             case 'Membrane' % User selects Membrane.
                current_data = membrane_data;
             case 'Sinc' % User selects Sinc.
                current_data = sinc_data;
             end
          end
      
       % Push button callbacks. Each callback plots current_data in
       % the specified plot type.
     
       function surfbutton_Callback(source,eventdata) 
       % Display surf plot of the currently selected data.
          surf(current_data);
       end
     
       function meshbutton_Callback(source,eventdata) 
       % Display mesh plot of the currently selected data.
          mesh(current_data);
       end
     
       function contourbutton_Callback(source,eventdata) 
       % Display contour plot of the currently selected data.
          contour(current_data);
       end 
     
    end
    I get the following error when trying to run it:
    Code:
    octave-3.2.4.exe:9> simple_gui2
    error: `uicontrol' undefined near line 10 column 9
    error: called from:
    error:   H:\MATLAB\simple_gui\simple_gui2.m at line 10, column 7
    How do I use jhandles?
    Is there currently any working solution for using uicontrol or equivalent in octave?

    edit: Progress!
    Code:
    octave-3.2.4.exe:10> pkg load jhandles
    warning: mark_as_command is obsolete and will be removed from a future version o
    f Octave
    octave-3.2.4.exe:11> simple_gui2
    error: `align' undefined near line 27 column 4
    error: called from:
    error:   H:\MATLAB\simple_gui\simple_gui2.m at line 27, column 4
    I guess jhandles is still a bit incomplete...

    Modified code which runs, but does not work correctly (no figure displayed):
    Code:
    function simple_gui2
    % SIMPLE_GUI2 Select a data set from the pop-up menu, then
    % click one of the plot-type push buttons. Clicking the button
    % plots the selected data in the axes.
     
       %  Create and then hide the GUI as it is being constructed.
       f = figure('Visible','off','Position',[360,500,450,285]);
     
       %  Construct the components.
       hsurf = uicontrol('Style','pushbutton','String','Surf',...
              'Position',[315,220,70,25],...
              'Callback',{@surfbutton_Callback});
       hmesh = uicontrol('Style','pushbutton','String','Mesh',...
              'Position',[315,180,70,25],...
              'Callback',{@meshbutton_Callback});
       hcontour = uicontrol('Style','pushbutton',...
              'String','Countour',...
              'Position',[315,135,70,25],...
              'Callback',{@contourbutton_Callback}); 
       htext = uicontrol('Style','text','String','Select Data',...
              'Position',[325,90,60,15]);
       hpopup = uicontrol('Style','popupmenu',...
              'String',{'Peaks','Membrane','Sinc'},...
              'Position',[300,50,100,25],...
              'Callback',{@popup_menu_Callback});
       ha = axes('Units','Pixels','Position',[50,60,200,185]); 
       % align([hsurf,hmesh,hcontour,htext,hpopup],'Center','None');
       
       % Create the data to plot.
       peaks_data = peaks(35);
       membrane_data = peaks();
       [x,y] = meshgrid(-8:.5:8);
       r = sqrt(x.^2+y.^2) + eps;
       sinc_data = sin(r)./r;
       
       % Initialize the GUI.
       %Create a plot in the axes.
       current_data = peaks_data;
       surf(current_data);
       % Assign the GUI a name to appear in the window title.
       set(f,'Name','Simple GUI')
       % Move the GUI to the center of the screen.
       % movegui(f,'center')
       % Make the GUI visible.
       set(f,'Visible','on');
    
       % Change units to normalized so components resize 
       % automatically.
       set([f,ha,hsurf,hmesh,hcontour,htext,hpopup],...
       'Units','normalized');
       
       %  Callbacks for simple_gui2. These callbacks automatically

             % Determine the selected data set.
             str = get(source, 'String');
             val = get(source,'Value');
             disp(str);
             disp(val);
             % Set current data to the selected data set.
             switch str{val};
             case 'Peaks' % User selects Peaks.
                current_data = peaks_data;
             case 'Membrane' % User selects Membrane.
                current_data = membrane_data;
             case 'Sinc' % User selects Sinc.
                current_data = sinc_data;
             end
          end
      
       % Push button callbacks. Each callback plots current_data in
       % the specified plot type.
     
       function surfbutton_Callback(source,eventdata) 
       % Display surf plot of the currently selected data.
          surf(current_data);
       end
     
       function meshbutton_Callback(source,eventdata) 
       % Display mesh plot of the currently selected data.
          mesh(current_data);
       end
     
       function contourbutton_Callback(source,eventdata) 
       % Display contour plot of the currently selected data.
          contour(current_data);
       end 
     
    end
    Still looking for a better solution... :'(
