Re: [Vala] Purple.CoreUiOps

[Joseph Montanez <jmontanez gorilla3d com>]

I got around it. I had to edit the purple.vapi and change it from a
class to struct. However moving along I had to change more classes to
structs. And now I am stuck with callbacks. I am not strong enough
with VAPI's to even know what they heck I am even doing...

Example, I see:
        [CCode (cheader_filename = "purple.h")]
        [Compact]
        public class EventLoopUiOps {
                public weak GLib.Callback input_add;
                public weak GLib.Callback input_get_error;
                public weak GLib.Callback input_remove;
                public weak GLib.Callback timeout_add;
                public weak GLib.Callback timeout_add_seconds;
                public weak GLib.Callback timeout_remove;
        }

and changed it too:
        [CCode (cheader_filename = "purple.h")]
        [Compact]
        public struct EventLoopUiOps {
                public weak GLib.Callback input_add;
                public weak GLib.Callback input_get_error;
                public weak GLib.Callback input_remove;
                public weak GLib.Callback timeout_add;
                public weak GLib.Callback timeout_add_seconds;
                public weak GLib.Callback timeout_remove;
        }

Then I see:
        [CCode (cheader_filename = "purple.h")]
        public static uint input_add (int fd, Purple.InputCondition cond,
Purple.InputFunction func);

Now when I try to set input_add:
        uint my_input_add(int fd, Purple.InputCondition condition,
Purple.InputFunction func)

        Purple.EventLoopUiOps glib_eventloops = Purple.EventLoopUiOps() {
                input_add = my_input_add,
                input_remove = GLib.Source.remove,
                input_get_error = null,
                timeout_add = GLib.Timeout.add,
                timeout_add_seconds = GLib.Timeout.add_seconds,
                timeout_remove = GLib.Source.remove
        };

I get "Invalid type for member `input_add'". I am going to take a wild
guess and say that in purple.vapi I need to add some [something that
fixed this] to let me add parameters to a callback?
