Hi

I want to open a second GUI from a pushbutton in mainGUI, that new GUI is only for input of values(7 variables).These values will be used in main, in a function. After that, i need to plot the result of the funtion with another standard function.

In the new GUI i need to define the variables? How to use de setappdata and getappdata with all variables?

I suggest having a look at FAQ 3.F

http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.3F

Matt Fig also has some nice examples on the FEX

% Add a brand new variable on to the handles structure.

handles.myNewVariable = 0;

it must be in function data_OpeningFcn(hObject, eventdata, handles, varargin) or in function edit1_Callback(hObject, eventdata, handles)?

HI again, finally it opens a new GUI where i can input 7 variables, but i don't undersand how it save the values. i want to push a buttom then it save the values and send them to the main GUI.

a = get(handles.edit1_editText,'String');

i add this line in "function pushbutton1_Callback(hObject, eventdata, handles) " and shows me a lot of errors after that.

programming in c++ i can save variables in a second function and then i use those values in main function, how can i do the same here?

Please help me
