Thu Jul 5 21:53:46 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkbbox.[ch] gtk/gtkbox.[ch] gtk/gtk[hv]bbox.c: Patch from Gregory Merchan to add gtk_button_box_set_secondary(), which separates the child into a separate group from the normal buttons. (#56331) * gtk/gtkdialog.c: Make help buttons secondary by default. * gtk/gtkbbox.c: Added a child property "secondary". * gtk/testgtk.c: Turn on the help button for the color selector to check that it properly appears as secondary.
