Re: Re: GtkHTML next set of questions...

in the header part of html.overides (-> which becomes gen_html.c) it is assigned in the constants part.. regards alan Steph wrote:

I hate to quote over, but where *are* you registering le_ gtkhtmlstream? ----- Original Message ----- From: "Alan Knowles" <alan_k@hklc.com> To: <php-gtk-dev@lists.php.net> Sent: Tuesday, October 09, 2001 5:05 PM Subject: [PHP-GTK-DEV] 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,

I'm not a Zend guru myself. parse_args returns a zval* to your resource; not the resource directly: Try the following: zval *resource; int resource_type; if (!php_gtk_parse_args(ZEND_NUM_ARGS(), "rsi", &resource, &buffer, &size)) return; gs = zend_list_find(Z_RESVAL_P(resource), &resource_type); if (!gs || resource_type != le_gtkhtmlstream) { php_error(... return; } On Sat, Oct 06, 2001 at 05:15:33PM -0000, Alan Knowles wrote :

The two functions below illustrate the issue - gtk_html_begin returns a struct, GtkHTMLStream gtk_html_write uses this as one of it's inputs to determine where to send the data.. I have attempted to wrap the return value into a PHP Resource and defined a simple struct to wrap the real one.. however I dont seem to be able to get the address back out of the struct.. (or am even sure that I am setting it correctly)... suggestions, other good (simple) examples of code doing something similar would be helpfull.. regards alan typedef struct { GtkHTMLStream *htmlstream;
