If you set 'min' to 0 and 'max' to 10, you will be able to select multiple strings. Once you have that you can get the choices by:

C = get(U,{'string','value'})
C = C{1}(C{2})

Then set the 'string' property of the other listbox to C.

I already knew that part of 'set '...min' to 0 and 'max' to 10...'. Now i can't save the selected elements to a matrix and then show them on other listbox...

Interesting, it seems to work for me...

U = uicontrol('style','listbox',...

'units','pix',...

'string',{'Poodle';'stubb';'false';'together';'spanish'},...

'pos',[10 10 50 100],...

'min',0,'max',10,...

'callback',['C = get(gcbo,{''string'',''value''});',...

'set(U(2),''string'',C{1}(C{2}))'])

U(2) = uicontrol('style','listbox',...

'units','pix',...

'string','',...

'pos',[80 10 50 100],'min',0,'max',10)

Set the 'Max' property of the listbox to be at least 2 greater than the 'Min' property. You will then be able to select multiple items in the usual ways (e.g., click-and-drag or control-click or as appropriate for your OS.) The listbox Value property will return an array of the indices of all the currently selected entries.

Note: the Callback will be called every time the selection changes, so if you are adding entries one by one using control or alt, then multiple callbacks will be generated.

Thanks for help. I already knew how to select multiple elements from a listbox. Now i want to save the selected elements to a matrix or anything like that and then show them in another listbox. Do you have any ideas how to do this?

[Matt Fig]

See the example I show above...

Have you tried using the 'handles' structure to save the data in the callback of the first listbox and then displaying using a callback for the second listbox?
