The documentation for the prototype for the callback > for the "value-changed" signal for the GtkAdjustment class follows:
It's not the signal, it's how you're connecting to it. > I then registered my callback, as shown below: > > printf( "main: hadjustment created. Adjust = 0x%p. Data = 0x%p.\n", > hadjustment, > (gpointer)0x1234 > ); > gtk_signal_connect_object( > GTK_OBJECT( hadjustment ), > "value-changed", > (GtkSignalFunc)value_changed_callback, > (gpointer)0x1234 > ); gtk_signal_connect_object() connects the callback with a flag enabled that switches the position of the gpointer "data" value and the GtkAdjustment "object" value in the callback. The positions of any other values passed to the callback are unchanged. Note that this is not the same as the behavior of the gtk+-2.0 g_signal_connect_object(), which does something quite different. To get the callback arguments in the same order as the prototype, use gtk_signal_connect() (note, no _object).
