Cell array menu image acquisition error

Hello,

I wrote a cell array menu because I wanted to use themenu style that the image acquisition toolbox uses. It looks like this:

function main(~)

cell_list = {};
fig_number = 1;
title_figure = 'Test';

cell_list{1,1} = {'1.Calibration','calib_gui;'};
cell_list{2,1} = {'2.Stereo Calibration','stereo_gui;'};
cell_list{3,1} = {'3.Choose/Rename Images','rename_images;'};
cell_list{4,1} = {'4.Record','record;'};
cell_list{5,1} = {'Exit',['disp(''Goodbye.''); close(' num2str(fig_number) ');']};

show_window(cell_list,fig_number,title_figure,290,18,0,'clean',12);
end

Now if I click on 4.Record, it calls the function and then it should ceate another figure, containing two side by side previews of my two cameras. But I can't get it to work and I think its because of the show_window command? Right now Im using this:

start(vid1);
start(vid2);
preview(vid1);
preview(vid2);

But if I want to get a good menu, do I have to use something like GUIDE?

What is show_window? It's not a Matlab function so far as I can see.

Hey Adam,

this function is inside the Camera Calibration Toolbox for Matlab if you download this zip package.

function show_window(cell_list,fig_number,title_figure,x_size,y_size,gap_x,font_name,font_size)

if ~exist('cell_list')
    error('No description of the functions');
end

if ~exist('fig_number')
    fig_number = 1;
end
if ~exist('title_figure')
    title_figure = '';
end
if ~exist('x_size')
    x_size = 85;
end
if ~exist('y_size')
    y_size = 14;
end
if ~exist('gap_x')
    gap_x = 0;
end
if ~exist('font_name')
    font_name = 'clean';
end
if ~exist('font_size')
    font_size = 8;
end

figure(fig_number); clf;
pos = get(fig_number,'Position');

[n_row,n_col] = size(cell_list);

fig_size_x = x_size*n_col+(n_col+1)*gap_x;
fig_size_y = y_size*n_row+(n_row+1)*gap_x;

set(fig_number,'Units','points', ...
  'BackingStore','off', ...
  'Color',[0.8 0.8 0.8], ...
  'MenuBar','none', ...
  'Resize','off', ...
  'Name',title_figure, ...
'Position',[pos(1) pos(2) fig_size_x fig_size_y], ...
'NumberTitle','off'); %,'WindowButtonMotionFcn',['figure(' num2str(fig_number) ');']);

h_mat = zeros(n_row,n_col);

posx = zeros(n_row,n_col);
posy = zeros(n_row,n_col);

for i=n_row:-1:1
   for j = n_col:-1:1
      posx(i,j) = gap_x+(j-1)*(x_size+gap_x);
      posy(i,j) = fig_size_y - i*(gap_x+y_size);
   end
end

for i=n_row:-1:1
    for j = n_col:-1:1
        if ~isempty(cell_list{i,j})
            if ~isempty(cell_list{i,j}{1}) && ~isempty(cell_list{i,j}{2})
                h_mat(i,j) = uicontrol('Parent',fig_number, ...
                    'Units','points', ...
                    'Callback',cell_list{i,j}{2}, ...
                    'ListboxTop',0, ...
                    'Position',[posx(i,j)  posy(i,j)  x_size   y_size], ...
                    'String',cell_list{i,j}{1}, ...
                    'fontsize',font_size,...
                    'fontname',font_name,...
                    'Tag','Pushbutton1');
            end
        end
    end
end

The shown code is prone to bugs: ~exist('cell_list') checks for M- and Mex-files anywhere in the path, java classes and files and folders in the current directory. I would not rely on such code.

 But if I want to get a good menu, do I have to use something like GUIDE?

What exactly is a "good" menu?

[Marcel Liphardt]

Hey Jan,

well you kniów, if I push this button: cell_list{4,1} = {'4.Record','record;'};

Then I would like to get a menu containing two camera previews, one on the left and one on the right and some buttons.

And therefore I don't know the best way to do so.
