<p>
Sets the adjustment to be used as the "model" object for this range
widget. The adjustment indicates the current range value, the
minimum and maximum range values, the step/page increments used
for keybindings and scrolling, and the page size. The page size
is normally 0 for <a class="link" href="GtkScale.html" title="GtkScale"><span class="type">GtkScale</span></a> and nonzero for <a class="link" href="GtkScrollbar.html" title="GtkScrollbar"><span class="type">GtkScrollbar</span></a>, and
indicates the size of the visible area of the widget being scrolled.
The page size affects the size of the scrollbar slider.</p>

Ranges normally move from lower to higher values as the
slider moves from top to bottom or left to right. Inverted
