[javiercmx correo unam mx]

Hi list thanks Olivier

I have the  following

In this part I create a group of radiobutton:

 button = gtk_radio_button_new_with_label (NULL, "USER");
          gtk_signal_connect(GTK_OBJECT(button), "toggled",
                             GTK_SIGNAL_FUNC(op_user), NULL);
  
  gtk_box_pack_start (GTK_BOX (box2), button, FALSE, FALSE, 0);
  gtk_widget_show(button);
  
  group = gtk_radio_button_group (GTK_RADIO_BUTTON (button));
  button = gtk_radio_button_new_with_label(group, "DATA");
           gtk_signal_connect(GTK_OBJECT(button), "toggled",
                              GTK_SIGNAL_FUNC(op_data), NULL);
  gtk_box_pack_start (GTK_BOX (box2), button, FALSE, FALSE, 0);
  gtk_widget_show(button);
...
...

In this part I create a new button:

  button =gtk_button_new_with_label("OK");

I use the following:

  gtk_signal_connect(GTK_OBJECT(button), "clicked",
                     GTK_SIGNAL_FUNC(op_user), NULL);
but when compiling appears this message:

invalid cast from `GtkButton' to `GtkToggleButton'

I need the following:

If I prees the radiobutton "USER" and I press the button "OK" call the 
function op_user, but if I press the radiobutton "DATA" and I press the 
button "OK" call the function op_data


Any Ideas?
