<p><a class="link" href="GtkScaleButton.html" title="GtkScaleButton"><span class="type">GtkScaleButton</span></a> provides a button which pops up a scale widget.
|
||
This kind of widget is commonly used for volume controls in multimedia
|
||
applications, and GTK+ provides a <a class="link" href="GtkVolumeButton.html" title="GtkVolumeButton"><span class="type">GtkVolumeButton</span></a> subclass that
|

is tailored for this use case.</p>

<div class="refsect2">

<a name="id-1.3.9.9.10.3"></a><h3>CSS nodes</h3>

<p>GtkScaleButton has a single CSS node with name button. To differentiate
|
||
it from a plain <a class="link" href="GtkButton.html" title="GtkButton"><span class="type">GtkButton</span></a>, it gets the .scale style class.</p>
|
||
<p>The popup widget that contains the scale has a .scale-popup style class.</p>
