<p>
The <a class="link" href="GtkAdjustment.html" title="GtkAdjustment"><span class="type">GtkAdjustment</span></a> object represents a value which has an associated lower
and upper bound, together with step and page increments, and a page size.
It is used within several GTK+ widgets, including
<a class="link" href="GtkSpinButton.html" title="GtkSpinButton"><span class="type">GtkSpinButton</span></a>, <a class="link" href="GtkViewport.html" title="GtkViewport"><span class="type">GtkViewport</span></a>, and <a class="link" href="GtkRange.html" title="GtkRange"><span class="type">GtkRange</span></a> (which is a base class for
<a class="link" href="GtkHScrollbar.html" title="GtkHScrollbar"><span class="type">GtkHScrollbar</span></a>, <a class="link" href="GtkVScrollbar.html" title="GtkVScrollbar"><span class="type">GtkVScrollbar</span></a>, <a class="link" href="GtkHScale.html" title="GtkHScale"><span class="type">GtkHScale</span></a>, and <a class="link" href="GtkVScale.html" title="GtkVScale"><span class="type">GtkVScale</span></a>).
</p>
<p>
The <a class="link" href="GtkAdjustment.html" title="GtkAdjustment"><span class="type">GtkAdjustment</span></a> object does not update the value itself. Instead
it is left up to the owner of the <a class="link" href="GtkAdjustment.html" title="GtkAdjustment"><span class="type">GtkAdjustment</span></a> to control the value.
</p>
<p>
The owner of the <a class="link" href="GtkAdjustment.html" title="GtkAdjustment"><span class="type">GtkAdjustment</span></a> typically calls the
<a class="link" href="GtkAdjustment.html#gtk-adjustment-value-changed" title="gtk_adjustment_value_changed ()"><code class="function">gtk_adjustment_value_changed()</code></a> and <a class="link" href="GtkAdjustment.html#gtk-adjustment-changed" title="gtk_adjustment_changed ()"><code class="function">gtk_adjustment_changed()</code></a> functions
after changing the value and its bounds. This results in the emission of the
"value_changed" or "changed" signal respectively.

When setting multiple adjustment properties via their individual
setters, multiple "changed" signals will be emitted. However, since
the emission of the "changed" signal is tied to the emission of the
"GObject::notify" signals of the changed properties, it's possible
to compress the "changed" signals into one by calling
<code class="function">g_object_freeze_notify()</code> and <code class="function">g_object_thaw_notify()</code> around the
calls to the individual setters.
</p>
<p>
Alternatively, using a single <code class="function">g_object_set()</code> for all the properties
to change, or using <a class="link" href="GtkAdjustment.html#gtk-adjustment-configure" title="gtk_adjustment_configure ()"><code class="function">gtk_adjustment_configure()</code></a> has the same effect
of compressing "changed" emissions.
