Pausing the program for GUI

i have a code which does some calculation, then calls the GUI. In the GUI i have some options for user to select from. based on that answer, further calculation is done.

Function this = random(this)
    ...some calc
    ...some calc
    ...some calc
    ...some calc
    GUI % calls the GUI
    value = getappdata(0,'value') %gets the value from the GUI
    ...some calc
    ...some calc
end

the problem is when I compile, it calls the GUI and continues with the program. how do i make the program wait until a button is pressed in the GUI?

Use waitfor function

How exactly do i use this function. I have a apply button in my GUI, i want my main prgram to continue only when this button is pressed

Does GUI return its own handle? If so then you uiwait() on that handle. When you want to resume, either destroy that graphics object or else have your button call uiresume()

Don't think my GUI returns it's own handle. I'm trying with

waitfor(findobj('-regexp','Tag','Apply'))

where apply is the tag of the button. doesnt seem to work

How do you create the GUI? Surely all GUIs return their own handle?

[JA]

I created them with GUIDE.

% --- Executes on button press in Apply.
function Apply_Callback(hObject, eventdata, handles)
% hObject    handle to Apply (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
value  = get(handles.slider1,'Value');
setappdata(0,'final_value',value)
close()

this is my callback function of the button

[Adam]

But when you actually initialise the GUI, you can call it as e.g.

hGUI = MyGui;

to get the handle of the GUI, then use this with waitfor.
