Overriding url handler

[Chanwit Kaewkasi]

Hello all,

I'm new to Pidgin and trying to develop a plugin for it. I would like
my plugin to handle hyperlinks by itself.
But I cannot override the default signal behaviour of the
"url_clicked" event of GtkIMHtml, because the signal is currently
emitted with flag G_SIGNAL_RUN_FIRST.

gtkimhtml.c (Pidgin 2.4.3) line 1343:
	signals[URL_CLICKED] = g_signal_new("url_clicked",
						G_TYPE_FROM_CLASS(gobject_class),
						G_SIGNAL_RUN_FIRST,

Is it possible to change this value to G_SIGNAL_RUN_LAST, so my plugin
will be able to call g_signal_stop_emission_by_name() to change the
behaviour of the default handler.

Best regards,

Chanwit
