Re: GtkHTML next set of questions...

gtk_html_begin,write and end now all work thanks to the note below.... I am now looking at the callback signals for gtkhtml.. gtkhtml is supposed to work something like this.. create the gtkhtml object. connect url_requested to a function 'x' call gtk_html_begin, get the stream put the html into with gtk_html_write. call gtk_html_end. meanwhile.. if there is an image tag, a 'url_requested' call back is supposted to be emited. this signal is emitted with the object(Gtkhtml), the URL, a new HTMLStream as the parameters by adding a g_message prior to the call in htmlimage.c (from gtkhtml) I know that it is calling gtk_signal_emit_by_name with url_requested - but I'm not quite sure where php is picking up the callback.. as it does not appear to be doing anything - even emit warnings saying I dont know how to handle this.. clues would be good... :) thx alan since I know php-gtk wont know how to deal with the HTMLStream comming in, >----- Original Message ----- > From: Markus Fischer <mfischer@guru.josefine.at> > To: Alan Knowles <alan_k@hklc.com> > Sent: Mon, 8 Oct 2001 04:19:54 +0200 > Subject: Re: [PHP-GTK-DEV] using resources... for GtkHTMLStream > > Sorry I completely ignored this one in the first place as I was > to busy.
