Probably worth continuing on php-gtk-dev only...
I was getting a bit further with
MAKE_STD_ZVAL(myresource);
ZVAL_RESOURCE(myresource, gs) ;
/*ZEND_REGISTER_RESOURCE(myresource, gs, le_gtkhtmlstream); */
now the function does not segfault, but does not appear to pass resource around..
then function below is called when the browser is loading a webpage, and wants an
image,
it emits a signal 'url_requested', which I have added a method of html
connect_url_request.
this builds the callback data array in data, and calls this function.. - with a new
stream.
- theoretically, when you load the web page, you would get a number of these call for
each of the images. the callback routine would then either get from the cache or open
a non-blocking socket to get the file/image..
in theory a number of these streams could be open at one time (assuming the program
can be taught to multi task well...)
on the php side..
it is supposed to work like this...
$string = implode('',file("http://www.php.net";));
$gtkhtml = &new gtkhtml();
$gtkhtml->connect_url_request("my_url_callback");
$gtkhtml->load_from_string($string);
function my_url_callback($url,$stream) {
global $gtkhtml;
$string = implode('',file("http://www.php.net".$url));
$gtkhtml->write($stream,$string);
}
the code below just segfaults when url_requested is emitted.
with the modification above, $stream does not appear to be a resource... (although Im
still testing..)
thx
