never present; if <TT

if needed (that is, if the slider part of the bar would be smaller

than the trough - the display is larger than the page size).&#13;</P

>&#13;Used to add children without native scrolling capabilities. This is

simply a convenience function; it is equivalent to adding the

unscrollable child to a viewport, then adding the viewport to the

scrolled window. If a child has native scrolling, use

<A
HREF="gtkcontainer.html#GTK-CONTAINER-ADD"
>gtk_container_add</A
>() instead of this function.&#13;</P
><P
>&#13;The viewport scrolls the child by moving its <A
HREF=../gdk/gdk-windows.html#GDKWINDOW
>GdkWindow</A>, and takes the

size of the child to be the size of its toplevel <A
HREF=../gdk/gdk-windows.html#GDKWINDOW
>GdkWindow</A>. This will

be very wrong for most widgets that support native scrolling; for

example, if you add a <A
HREF="gtkclist.html"
>GtkCList</A
> with a viewport, the whole widget will

scroll, including the column headings. Thus <A
HREF="gtkclist.html"
>GtkCList</A
> supports

scrolling already, and should not be used with the <A
HREF="gtkviewport.html"
>GtkViewport</A
> proxy.&#13;</P
><P
>&#13;A widget supports scrolling natively if the

set_scroll_adjustments_signal field in GtkWidgetClass is non-zero,

i.e. has been filled in with a valid signal identifier.&#13;</P
