Re: problem with GUI

Then i have to declare handle in the callback? I mean to write :
function hedit_fmin_Callback (hObject, eventdata, handle)

Dear friends,

I'm new with GUI and i have to problem when i take the data
from
it...

I do the next
--------------------------------------------------
function hboton_OK_Callback (hObject, eventdata)
function hedit_fmin_Callback (hObject, eventdata)
auxiliar=str2double(get(hObject,'String'));
%Ahora hemos de controlar que haya puesto realmente un numero
if isnan(auxiliar)
errordlg('Debes introducir un valor numerico en frec. min',
'Variable falsa', 'modal');
return
else
freqmin=auxiliar;
end
--------------------------------------------------

If i do it this way, Could I use the variable freqmin after? Or
should i use handle?¿?

Thanks for you help !!!

Try

handles.freqmin = auxiliar;
% Update handles structure
guidata(hObject, handles);
.
