gtk/gtkclist.c (adjust_adjustments) gtk/gtklayout.c

Mon Feb 18 14:17:59 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkclist.c (adjust_adjustments)
        * gtk/gtklayout.c (gtk_layout_size_allocate)
        * gtk/gtktextview.c (gtk_text_view_size_allocate)
        * gtk/gtktreeview.c (gtk_tree_view_size_allocate)
        * gtk/gtkviewport.c (gtk_viewport_size_allocate):
        Standardize on a page increment of page minus 1 line
        rather than half a page (#51027, Eric Fischer)

        * gtk/gtkviewport.c (gtk_viewport_size_allocate):
        Change step increment to be 0.1 * page_size height rather than
        a fixed 10 pixels.
