In case you are referring to the List Box this is what I found in the documentation:

When the list box Callback callback is triggered, the list box Value property contains the index of the selected item, where 1 corresponds to the first item in the list. The String property contains the list as a cell array of strings.

This example retrieves the selected string. It assumes listbox1 is the value of the Tag property. Note that it is necessary to convert the value returned from the String property from a cell array to a string.

function listbox1_Callback(hObject, eventdata, handles)
index_selected = get(hObject,'Value');
list = get(hObject,'String');
item_selected = list{index_selected}; % Convert from cell array
                                      % to string

You can also select a list item programmatically by setting the list box Value property to the index of the desired item. For example,

set(handles.listbox1,'Value',2)

selects the second item in the list box with Tag property listbox1.

hello and thank's for your answer but I what I want to get it's handles of this element like handles = 3.0990e+003...

I might be wrong but the selected elements don't have their own handle, you must use the handle for the list box and the Value attribute.

Paulo is correct: selected entries do not have their own handles. They do not have their own properties either.

Sometimes it would be nice if the entries of a listbox or popup could be text boxes so you could use latex for fancier labels, but that isn't implemented.
