<p>When setting multiple adjustment properties via their individual
|

setters, multiple <a class="link" href="GtkAdjustment.html#GtkAdjustment-changed" title="The “changed” signal"><span class="type">“changed”</span></a> signals will be emitted.
|
||
However, since the emission of the <a class="link" href="GtkAdjustment.html#GtkAdjustment-changed" title="The “changed” signal"><span class="type">“changed”</span></a> signal
|
||
is tied to the emission of the <span class="type">“notify”</span> signals of the changed
|
||
properties, it’s possible to compress the <a class="link" href="GtkAdjustment.html#GtkAdjustment-changed" title="The “changed” signal"><span class="type">“changed”</span></a>
|
||
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 <a class="link" href="GtkAdjustment.html#GtkAdjustment-changed" title="The “changed” signal"><span class="type">“changed”</span></a> emissions.</p>
