Problems with gui (return of the variable)

Hello everyone, I am running a main program and I want to
insert a gui function to stop it.

It look like very obvious that it cant so complicated, but I have problems with it:

The main program:

clear all
clc
global x

x=1

while 1
hstoprun=uicontrol (gcf,'String','stop','Position',[20,40,60,20],'Callback','stoprun');

if x==0
break
end

end


This is the gui-function.

XXXXXXXXXXXXXXXXx
function stoprun (obj, event, string_arg)
global snrtest

x=0

XXXXXXXXXXXXXXXX


The weird thing is that the gui-function (stoprun) do not return the new value x=0 to the main program.

And therefore the main program don't stop


Any idea, why the new value of x don't return to the main program?

Cheers,

Jose.





When I put this command in a part of my code, I do not know why

could you put x as a global in there too? (Just off the top of my
head, that's what i see might help)
function stoprun (obj, event, string_arg)
global snrtest x

x=0
