2001-06-05 Havoc Pennington <hp@redhat.com> * gtk/gtkspinbutton.c (gtk_spin_button_set_range): clamp the value to the range that was set * gtk/gtkrange.c: add value_changed signal, primarily intended for use with GtkScale (gtk_range_set_increments): new function (gtk_range_set_range): new function with weird name (gtk_range_set_value): new function (gtk_range_get_value): new function * gtk/gtkspinbutton.c (gtk_spin_button_get_value): rename from gtk_spin_button_get_value_as_float(). Compat #define added for get_value_as_float. * gtk/gtkhscale.c (gtk_hscale_new_with_range): new function * gtk/gtkvscale.c (gtk_vscale_new_with_range): new function 2001-06-05 Havoc Pennington <hp@redhat.com> * test-loaders.c (main): use putenv not setenv, reported by Armin Theissen
