Sat Jan 23 01:44:43 1999 Lars Hamann <lars@gtk.org> * gtk/gtkspinbutton.c (gtk_spin_button_get_value_as_int) (gtk_spin_button_get_value_as_float): removed extra gtk_spin_button_update calls again. * gtk/gtkclist.c (gtk_clist_unmap): unblock dnd signal handler if neccessary * gtk/gtknotebook.c (gtk_notebook_button_press): grab_focus before switch_page (gtk_notebook_set_shape): don't use cur_page if it's NULL.
