Yes, that's a known gtk-doc issue with the developer.gnome.org
scripts; the actual page is:
https://developer.gnome.org/gdk3/stable/gdk3-Events.html# GdkEventMask
You probably want to install DevHelp and have the documentation
locally, instead of using the website.

typically use strings, not an enumeration, for flags; see:
http://gtk2-perl.sourceforge.net/doc/pod/Glib.html#PERL_ VERSUS_C
the section about flags. So if you want to handle pointer events, you
want to use:
[ "button-press-mask", "button-release-mask" ]
and if you want to get scrolling events, you want to add "scroll-mask"
and "smooth-scroll-mask".
Ciao,
Emmanuele.
