Thread Subject: problem with GUI

hi,
i took a look on google and also matlab help but i gave up
finished with a total mess in my head:/

can anyone describe me how i can send arguments between
functions in GUI?

i've got smth like that:
3 functions (separate m-files). 'gui' is the main file, in
witch i've got 2 buttons.
if i click on the first one another function will be
called, and this functions should return arguments (few) to
the main program, 'gui'. then, if i click the second
button, the third function will be called and these
arguments should be send to it..

i hope i wrote clearly what my problem is.

 kind regards,
     misty

Hai,

Tryout the following,

GUI.m
function Button1_Callback(hObject, eventdata, handles)
global out1 out2 ....
[out1,out2..] = m_file1(arg1,arg2...)


function Button2_Callback(hObject, eventdata, handles)
global out1 out2 ....
[out11,out12..] = m_file2(out1,out2,....)

Hope this will help u .. if not clear.. plz get back

hmm, maybe i'll just show a part of my program:

main function:

function varargout = gui_model2(varargin)

button1 = uicontrol
('Style','PushButton','String','Deviation','Position',button
Position1,'Callback','deviation(a,b,c,d)');
button2 = uicontrol('Style','PushButton','String','Count
deviation','Position',buttonPosition3, 'Callback', 'setMouse
');

setMouse.m:

function setMouse
% do smth

return a,b,c,d

deviation.m

function deviation(A,B,C,D)

i gave up and i tried to do GUI using GUIDE, not manualy as
i tried before.
but still i do not know how to send arguments between
callback functions or values from
edit field..

can anyone explain my simply how to use these 'handles' to
send/get things between m-files
or functions?

You can associate data with object using "setappdata" and
"getappdata". But since you are designing a GUI, then
associating the data to be shared to the figure itself is
the easiest way.

eg.
function send()
guiFigure = figure;
A = 1:100;
B = sin(A);
handles.A = A;
handles.B = B;
guidata(guiFigure, handles);
end

function receive(hObject, eventdata)
handles = guidata(guiFigure);
A = handles.A;
B = handles.B;

This is really easy!
