You probably want to install DevHelp and have the documentation<br>
locally, instead of using the website.<br>
<span class=""><br>
&gt; Could anyone point me to some docs that would help me understand what<br>
&gt; I pass to gtk_widget_add_events? I have some ( perl ) code that I was<br>
&gt; given in the gtk-perl list to add some events for catching mouse<br>
&gt; events:<br>
&gt;<br>
&gt; $drawing_area-&gt;add_events(<wbr>0x004|0x100|0x200);<br>
<br>
&gt; This works, but:<br>
&gt;   a) I don&#39;t know where these values are coming from and what they are<br>
&gt;   b) I&#39;d like to also catch mouse wheel events now<br>
&gt;<br>
&gt; Any tips?<br>
<br>
</span>This is a gtk-perl-list question, really. The Perl bindings for GLib<br>
typically use strings, not an enumeration, for flags; see:<br>
<br>
   <a href="http://gtk2-perl.sourceforge.net/doc/pod/Glib.html#PERL_VERSUS_C" \
rel="noreferrer" target="_blank">http://gtk2-perl.sourceforge.<wbr>net/doc/pod/Glib.html#PERL_<wbr>VERSUS_C</a><br>
 <br>
the section about flags. So if you want to handle pointer events, you<br>
want to use:<br>
<br>
   [ &quot;button-press-mask&quot;, &quot;button-release-mask&quot; ]<br>
<br>
and if you want to get scrolling events, you want to add &quot;scroll-mask&quot;<br>
and &quot;smooth-scroll-mask&quot;.<br>
<br>
Ciao,<br>
