PHP-GTK consists of about 100 classes, 1000 methods, and 600 constants.. ..not counting the extensions Writing them by hand would become mind-numbingly tedious But the generator helps tremendously and eases development of new PHP-GTK extensions The header files are converted to definition (.defs) files which are converted to C code It is possible to hide any method or override it a custom implementation Alan Knowles has started to turn this into a generic PHP code generator.
