Data grid in GUI (Linux)

Hello,

I need to display the user data in the GUI, using some kind of table
(data grid). I don't need the editing ability - all I need is to
display them.

As far as I know there's no such UI element in the Matlab itself, and
here I've found only some ActiveX controls, but I'm working on Linux,
so it's useless for me. Is there some way to display a simple table?

Thanks a lot in advance.

If you have R14 ( sp2 ?? ) there is the command uitable. Do

help uitable

I've had a little play with the object and I'm not too sure how usable
it is. Here is an example of it's use but it's a bit fiddly.

function out = use_table

data = rand(3);
colnames = {'X-Data', 'Y-Data', 'Z-Data'};
t = uitable(data, colnames,'Position', [20 20 250 100]);

t.DataChangedCallback = @change_fcn;

out = @get_data;

function out = get_data
out = data;
end

function change_fcn(src, ev)
row = ev.getEvent.getFirstRow;
col = ev.getEvent.getColumn;
d = src.TableModel.getValueAt(row,col);
data(row+1,col+1) = str2num(d);
end


end

The trick to make this more usable would be to create some
implementation of javax.swing.TableModel that has a friendly matlab back
end such like so that you can do the following somehow.

function use_table

data = rand(10);

% Create a uitable with a simple matlab data model. Specify
% that the cell class will be all of double.
t = uitable(@getfun, @setfun, 'double');

function val = getfun(t, row, col)
val = data(row,col);
end

function setfun(t, row, col, val)
data(row,col) = val;
end

end

Wasn't as hard as I thought ....

You use the little tool detailed on the website as below

function use_table

data = rand(4);

% Create a uitable with a simple matlab data model. Specify
% that the conversion class will be %g.
t = xtargets_uitable(4,4, @getfun, @setfun, '%g');

function val = getfun( row, col)
val = data(row,col);
end

function setfun( row, col, val)
data(row,col) = val;
end

end
