2001-08-26 Alexander Larsson <alla@lysator.liu.se> * gtk/gtkbutton.[ch]: Add properties for labels, mnemonics and stock items. Added C accessor functions for the properties. Removed deprecated button->child. * gtk/gtkradiobutton.c: * gtk/gtktogglebutton.c: Update to use the functions in GtkButton. * gtk/gtkcheckbutton.c: Update to use the functions in GtkButton. Changed size allocation of child. Now only gets as much space as it requests. * gtk/gtkclist.c: Don't use GtkButton->child * gtk/gtklabel.c: Fixed typo in docs
