<a name="GtkButton.description"></a><h2>Description</h2>
<p>The <a class="link" href="GtkButton.html" title="GtkButton"><span class="type">GtkButton</span></a> widget is generally used to trigger a callback function that is
called when the button is pressed. The various signals and how to use them
are outlined below.</p>
<p>The <a class="link" href="GtkButton.html" title="GtkButton"><span class="type">GtkButton</span></a> widget can hold any valid child widget. That is, it can hold
almost any other standard <a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a>. The most commonly used child is the
<a class="link" href="GtkLabel.html" title="GtkLabel"><span class="type">GtkLabel</span></a>.</p>
<div class="refsect2">
<a name="id-1.3.9.2.11.4"></a><h3>CSS nodes</h3>
<p>GtkButton has a single CSS node with name button. The node will get the
style classes .image-button or .text-button, if the content is just an
image or label, respectively. It may also receive the .flat style class.</p>
<p>Other style classes that are commonly used with GtkButton include
.suggested-action and .destructive-action. In special cases, buttons
can be made round by adding the .circular style class.</p>
