MATLAB: Use of list box Matlab GUI

Question

Hi there,

I want to know how can I link two list box and then pass the values of both list boxes in a text box using a push button.

Any suggestion will be appreciated.

Answer 1

In the callback for the push button:

str1 = cellstr(get(handles.listbox1, 'string'));
val1 = get(handles.listbox1, 'value');
if isempty(val1)
  selection1 = '';
else
  selection1 = str1{val1};
end
str2 = cellstr(get(handles.listbox2, 'string'));
val2 = get(handles.listbox2, 'value');
if isempty(val2)
  selection2 = '';
else
  selection2 = str2{val2};
end
combined_selection = {selection1; selection2};
set(handles.textbox, 'string', combined_selection);
