Hi all, Get out of the loop "for" for guide
"
---------------------------------------------------------------------
K=handles.b
function pushbutton2_Callback(hObject, eventdata, handles)
for i=1:n;
%event
if (K==1)
break
end
end
guidata(hObject, handles);
---------------------------------------------------------------------
function rd_1_Callback(hObject, eventdata, handles)
if (get(hObject,'Value') == get(hObject,'Max'))
handles.b=1;
else
handles.b=2;
end
guidata(hObject, handles);
----------------------------------------------------------------------
trying "K=handles.b" Instead of typing "K=1" above
I want,while loop "for", any button or raddio_button or listbox ,stop with an impact.

I don't think the user wants to hit return every loop iteration!
pause(.001)
