Sun Jun 24 11:29:35 2001 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkimage-x11.c (gdk_image_new): Fix stupid error introduced last night that was making things decidedly not work. * gtk/*.[ch]: Patch from Kristian Rietveld adding 80 getters so that we have getter/setter pairing everywhere it makes sense. (#55767) * gtk/gtkradiobutton.[ch] gtk/gtktoolbar.c tests/testgtk.: Rename gtk_radio_button_group to gtk_radio_button_get_group, add a deprecated compat macro. (#55516) * gtk/gtklabel.[ch]: Add functions gtk_label_set/get_use_underline(), gtk_label_set/get_use_markup(), gtk_label_set_label(), which mirror the property API for GtkLabel. Make gtk_label_get_attributes() only reflect the attributes set by gtk_label_set_attributes. * gtk/gtknotebook.c (gtk_notebook_set_current_page) gtk/gtkcompat.h: Rename from gtk_notebook_set_page().
