Sun Jul 19 12:19:16 1998 Stefan Jeske <stefan@gtk.org> * gtk/gtkprogress.c gtk/gtkprogress.h gtk/gtkprogressbar.c gtk/gtkprogressbar.h gtk/Makefile.am gtk/gtk.h gtk/testgtk.c: Introduced generic GtkProgress widget. Derived GtkProgressBar from GtkProgress. Made GtkProgressBar much more flexible (see testgtk).
