MATLAB: Update GUI from from call back

Question

Hi I am new to using GUIs in Matlab so this is probably something simple!

I have created a GUI using the GUIDE template. It has a popup menu and a listbox. I want the contents of the listbox to be dependent on what has been specified in the popup menu. In the callback function of the popmenu I use the commands:

contents = cellstr(get(hObject,'String'));

handles.Selection = contents{get(hObject,'Value')};

guidata(hObject, handles);

This updates the field handles.Selection which is used to populate the listbox

How do I now get the GUI to update the listbox with the new value of handles.Selection? Is there come kind of function command I need to do this?

thanks

Oli

Answer 1

Does this do it?

set(handles.listbox_handle,'String',contents{handles.Selection})

Also, I'm fairly sure that you don't need the cellstr function when getting "contents."
