Wed Mar 10 01:49:27 2004 Matthias Clasen <maclas@gmx.de> Fix #136614 in a better way: * gtk/gtkoptionmenu.c (gtk_option_menu_init): Undo the last change. * gtk/gtkbutton.c (struct _GtkButtonPrivate): Add a flag, align_set. * gtk/gtkbutton.c (gtk_button_init): Initialize align_set to 0. * gtk/gtkbutton.c (maybe_set_alignment): Rework to only set the alignment if priv->align_set is set. * gtk/gtkbutton.c (gtk_button_set_alignment): Set align_set to 1.
