I don't understand the reason for this particular callback construct but since in general user interface elements often need to be updated from callback functions and the recursiveness you describe is causing problems for GObject newbies, here's how to solve this problem: Either block the "value_changed" signal handler using g_signal_handlers_block_by_func() before you set the value and unblock it later or compare the set value with the new one and only set the value if the two differ.
