Used for button press and button release events. The
<em class="structfield"><code>type</code></em> field will be one of <a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a>,
<a class="link" href="gdk-Events.html#GDK-2BUTTON-PRESS:CAPS"><code class="literal">GDK_2BUTTON_PRESS</code></a>, <a class="link" href="gdk-Events.html#GDK-3BUTTON-PRESS:CAPS"><code class="literal">GDK_3BUTTON_PRESS</code></a>, and <a class="link" href="gdk-Events.html#GDK-BUTTON-RELEASE:CAPS"><code class="literal">GDK_BUTTON_RELEASE</code></a>.
</p>
<p>
Double and triple-clicks result in a sequence of events being received.
For double-clicks the order of events will be:
</p>
<div class="orderedlist"><ol type="1">
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-RELEASE:CAPS"><code class="literal">GDK_BUTTON_RELEASE</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-2BUTTON-PRESS:CAPS"><code class="literal">GDK_2BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-RELEASE:CAPS"><code class="literal">GDK_BUTTON_RELEASE</code></a></p></li>
</ol></div>
<p>
Note that the first click is received just like a normal
button press, while the second click results in a <a class="link" href="gdk-Events.html#GDK-2BUTTON-PRESS:CAPS"><code class="literal">GDK_2BUTTON_PRESS</code></a> being
received just after the <a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a>.
</p>
<p>
Triple-clicks are very similar to double-clicks, except that <a class="link" href="gdk-Events.html#GDK-3BUTTON-PRESS:CAPS"><code class="literal">GDK_3BUTTON_PRESS</code></a>
is inserted after the third click. The order of the events is:
</p>
<div class="orderedlist"><ol type="1">
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-RELEASE:CAPS"><code class="literal">GDK_BUTTON_RELEASE</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-2BUTTON-PRESS:CAPS"><code class="literal">GDK_2BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-RELEASE:CAPS"><code class="literal">GDK_BUTTON_RELEASE</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-3BUTTON-PRESS:CAPS"><code class="literal">GDK_3BUTTON_PRESS</code></a></p></li>
<li><p><a class="link" href="gdk-Events.html#GDK-BUTTON-RELEASE:CAPS"><code class="literal">GDK_BUTTON_RELEASE</code></a></p></li>
</ol></div>
<p>
</p>
<p>
For a double click to occur, the second button press must occur within 1/4 of
a second of the first. For a triple click to occur, the third button press
must also occur within 1/2 second of the first button press.
