Re: PHP-GTK2 - please test build - Instructions to help out.

Hi Alan, I'm trying to configure a build environment to build this on Win32 but I noticed that the include and lib paths in the .dsp files are pointing to php4 and not to php5. With the current CVS version pg php-gtk this should be fixed. When did you get these files ? I get a lot of warnings and errors at this time. Some are related to Zend and some to TSRMLS_*, but I'll ee if I can fix them. - Frank > GTK2 Full Status - And Instructions for helping out... > > > At present, PHP-GTK for Gtk2 is a working extension to some degree.... > On the +ve side: > - It should build against current CVS of PHP5 (eg. php-src HEAD) > - It has 1400 functions/methods auto generated from the defs file. > (gtk1 has 1000) > - It runs a slightly modified hello.php & fires up gtk.php from tests. > > I have just added the base code for callbacks aka $obj->connect($signal...) > > > Next on the TODO list: > - argumemnt parsing: - when the connect callsback, it sends argments via > g_closure_marshal. - these need converting into php variables.. - this > is one of the biger changes in gtk1/gt2 - and alot of the code in > main/gtk_object.c needs modifying to fix this.. > - more testing.. - and understaning of marshalling .. - at present it > appears to work.. - although it definatly needs more attention (eg. > making sure it's not leaking memory somewhere..) > - GObject.. - more support for GObject in the base code.. - all Gdk & > Gtk objects are based off of GObject now.. - so It should be alot > simpler to wrap some of the simpler objects that used to be structs.. > > ---------- BIG JOB - that anyone can help out with -------------- > > As you can guess Gtk has a huge number of widgets and methods. > > The php-Gtk build process is based around automatically building the > bindings from the C header files. - however, you can see in the gtk1 > bindings that the gtk.overrides file modifies the default behaviour for > a large number of widgets.. > > A simple example of this is GtkButton.. - the standard C code to create > button is > gtk_button_new(); > - this is the default constructor for the widget (NOTE THAT THERE ARE > NO ARGUMENTS), and is autogenerated as > > ----------------------------- > PHP_FUNCTION(gtk_button_new) > { > GtkObject *wrapped_obj; > > NOT_STATIC_METHOD(); > > if (!php_gtk_parse_args(ZEND_NUM_ARGS(), "")) { > php_gtk_invalidate(this_ptr); > return; > } > > wrapped_obj = (GtkObject *)gtk_button_new(); > if (!wrapped_obj) { > php_error(E_WARNING, "%s(): could not create GtkButton > object", > get_active_function_name(TSRMLS_C)); > php_gtk_invalidate(this_ptr); > return; > } > > php_gtk_object_init(wrapped_obj, this_ptr); > > } > ----------------------------- > > However in gtk1 - you are able to send a parameter like > $x = new GtkButton('the label'); > > so the gtk_button_new code is defined in gtk.overrides as: > ------------------------------------- > PHP_FUNCTION(gtk_button_new) > { > GtkObject *wrapped_obj; > gchar *text = NULL; > #ifdef PHP_WIN32 > gchar *utf8_text = NULL; > #endif > > NOT_STATIC_METHOD(); > > if (!php_gtk_parse_args(ZEND_NUM_ARGS(), "|s", &text)) { > php_gtk_invalidate(this_ptr); > return; > } > > if (text) { > #ifdef PHP_WIN32 > utf8_text = g_convert(text, strlen(text), "UTF-8", > GTK_G(codepage), NULL, NULL, NULL); > wrapped_obj = (GtkObject > *)gtk_button_new_with_label(utf8_text); > if (utf8_text) g_free(utf8_text); > #else > wrapped_obj = (GtkObject *)gtk_button_new_with_label(text); > #endif > } > else > wrapped_obj = (GtkObject *)gtk_button_new(); > > if (!wrapped_obj) { > php_error(E_WARNING, "%s(): could not create GtkButton > object", > get_active_function_name(TSRMLS_C)); > php_gtk_invalidate(this_ptr); > return; > } > > php_gtk_object_init(wrapped_obj, this_ptr); > } > > ------------------------------------- > > > Notice (apart from the windows #ifdefs - there is very little different > abou the two.. - the key difference being the reading of arguments.. > ------------------------------------- > if (!php_gtk_parse_args(ZEND_NUM_ARGS(), "|s", &text)) { > ------------------------------------- > and wheather or not it calls the method.. > ------------------------------------- > gtk_button_new_with_label(text) > or > gtk_button_new() > ------------------------------------- > > WHAT TO DO.... > If anyone wants to help out.. all they need to do is pick an Object > > look in gtk.overrides from current CVS, for all the methods that have > been overridden for that object..- add the code to the end of the > gtk.overrides in the new gtk2 version. and see if it builds.. > > -- if you can get any or all of the methods for an object to build.. - > let me know and I will add it to the new overrides file. > > The current working code is at.. > http://devel.akbkhome.com/php-gtk2-0.4.tgz > > Let me know if you interested in helping out. > > Regards > Alan > > > > > > > > > > > -- > Can you help out? > Need Consulting Services or Know of a Job? > http://www.akbkhome.com > > -- > PHP-GTK Development Mailing List (http://gtk.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php >
