How can I save a string from a uicontrol edit box into a a part of my structure ?

Hello,

I working on a Programmatic GUI. I have an editbox wich allow the user to enter a string. What I want is to save it into the GUI and not only into the callback function. My edtibox and the file into I want to save the string are in a Structure.

S.f = figure('Position', [500,150,1000,700], ...
             'name', 'GUI2');

S.eT_name      = uicontrol( 'Style', 'edit', ...
                          'Position', [400,100,200,50], ...
                          'FontSize', 15, ...
                          'BackgroundColor', 'white');

S.s_name = [];

function [] = eT_name_callback(varargin)
    S = varargin{3};
    s_Name = get(varargin{1}, 'String');
    display(s_Name);
    S.s_name = s_Name;
    display(S.s_name);

But the problem is, he is saving it only local. The second way I've tryed it, was with set. But it didn't worked also. I think it was because of a format file ... How can I solve it. One other question. Are set and get only for uicontrol or can i use it also to set a string into a variable that I created ?

Thank you in advance

You have to put your string into the handles structure as

handles.s_Name = s_Name;

and then save it with:

guidata(hObject, handles); % put this at the end of the callback

You can then use your string anywhere else in your gui as handles.s_Name

But is handle a special call ? I thought I can define what my handle is. So I'm giving to the function a handle called S. It's my structure array. But if I'm doing this it didn't worked :

S.f = figure('Position', [400,400,1000,400], ...
           'Name', 'Store data');

S.eT_name      = uicontrol( 'Style', 'edit', ...
                          'Position', [400,100,200,50], ...
                          'FontSize', 15, ...
                          'BackgroundColor', 'white');

S.pB_save       = uicontrol( 'Style', 'pushbutton', ...
                           'String', 'Save', ...
                           'Position', [700,75,200,50], ...
                           'FontSize', 20, ...
                           'BackgroundColor', 'red');

set(S.pB_save, 'Callback', {@pB_save_callback, S});
set(S.eT_name, 'Callback', {@eT_name_callback, S});

function [] = eT_name_callback(hObject, eventdata, S)
    s_Name = get(hObject, 'String');
    S.s_name = s_Name;
    guidata(hObject, S);

function [] = pB_save_callback(hObject, eventdata, S)
    display(S.s_Name);
