<p>Sets the minimum value of the adjustment.</p>
<p>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
<a href="../gobject/gobject-The-Base-Object-Type.html#g-object-freeze-notify"><code class="function">g_object_freeze_notify()</code></a> and <a href="../gobject/gobject-The-Base-Object-Type.html#g-object-thaw-notify"><code class="function">g_object_thaw_notify()</code></a> around the
calls to the individual setters.</p>
<p>Alternatively, using a single <a href="../gobject/gobject-The-Base-Object-Type.html#g-object-set"><code class="function">g_object_set()</code></a> 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.</p>
