The event structs contain data specific to each type of event in GDK.

<p>
A common mistake is to forget to set the event mask of a widget so that the
required events are received. See <a href="http://library.gnome.org/devel/gtk/unstable/GtkWidget.html#gtk-widget-set-events"><code class="function">gtk_widget_set_events()</code></a>.

<pre class="programlisting"></pre>
<p>
The <a class="link" href="gdk-Event-Structures.html#GdkEvent" title="union GdkEvent"><span class="type">GdkEvent</span></a> struct contains a union of all of the event structs,
and allows access to the data fields in a number of ways.
</p>
<p>
The event type is always the first field in all of the event structs, and
can always be accessed with the following code, no matter what type of event
it is:
</p>
<div class="informalexample">
<table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td class="listing_lines" align="right"><pre>1
2
3</pre></td>
<td class="listing_code"><pre class="programlisting"><span class="normal"><a href="gdk-Event-Structures.html#GdkEvent">GdkEvent</a> </span><span class="symbol">*</span><span class="normal">event</span><span class="symbol">;</span>
<span class="normal"><a href="gdk-Events.html#GdkEventType">GdkEventType</a> type</span><span class="symbol">;</span>

</tr>
</tbody>
</table>
</div>
<p>
</p>
<p>
To access other fields of the event structs, the pointer to the event can be
cast to the appropriate event struct pointer, or the union member name can be
used. For example if the event type is <a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</code></a> then the x coordinate
of the button press can be accessed with:
</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 class="orderedlist" type="1">
<li class="listitem"><p><a class="link" href="gdk-Events.html#GDK-BUTTON-PRESS:CAPS"><code class="literal">GDK_BUTTON_PRESS</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>
</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.

Proximity events are generated when using GDK's wrapper for the
XInput extension. The XInput extension is an add-on for standard X
that allows you to use nonstandard devices such as graphics tablets.
A proximity event indicates that the stylus has moved in or out of
contact with the tablet, or perhaps that the user's finger has moved
in or out of contact with a touch screen.
