Get multiples item from listbox
显示 更早的评论
Dear all,
I have a listbox in a GUI from which I want to retrieve the value of different items. I have set up the "Max" value to 2 (and the "Min" to 0). With this I can select 2 items in my list. But, when I want to get the value of the two selected items with:
contents = cellstr(get(hObject,'String'))
selected_file=contents{get(hObject,'Value')}
It is only giving me the value of the first item in the list as a string.
How I can get an array of the two selected items then? I'm sure it is very simple but I can't find the solution.
Thanks for your help.

selected_file=contents( get(hObject,'Value') )
should work. Or just
selected_file = hObject.String( hObject.Value );
in one line (R2014b or later - the equivalent get style works for earlier versions)

Well in your original question you extracted the string into contents so I used what you had written there and didn't bother to repeat it.
Older Matlab versions contained the function popupstr for this job. Unfortunately this small but useful piece of code has been removed. Here is a replacement, which handles single and multi-selction listboxes and popup menus, strings, CHAR matrices and cell strings:
selected_items = GetSelection(hObject)
