I'm trying to build a simple gui for my program, now i have to save the user input, but i can't retrieve data from callback function.
h.d = figure('Position',[300 300 400 200],'Name','Elaborazione di Mesh poligonali'); % position = [ x y xDim yDim ]
h.txt1 = uicontrol('Parent',h.d,... 'Style','text',... 'Position',[20 150 120 20],... 'String','Inserisci nome:');h.txtBox1 = uicontrol('Parent',h.d,... 'Style','edit',... 'Position',[140 150 50 20],... 'String','Esempio',... 'Callback',@store_img);h.btnOk = uicontrol('Parent',h.d,... 'Style','pushbutton',... 'Position',[85 20 70 25],... 'String','Avanti',... 'Callback',@btn_ok);uiwait;disp(h.txtBox1.UserData)% Salvataggio input dell'utente
function store_img(hObject, event) % hObject handle to pushbutton1 (see GCBO)
% event reserved - to be defined in a future version of MATLAB
data = hObject.String; hObject.UserData = data;endfunction btn_ok( hObject, event) close(gcf);endCommand Window:Invalid or deleted object.Error in prova (line 20)disp(h.txtBox1.UserData)
