Re: [Vala] gtk-clutter question

You haven't initialized Clutter. Use ClutterGtk.init() instead of
Gtk.init().

Ciao,

I hope this is the correct place to ask this question.  I started to play
around with Vala, Gtk, and Clutter.  I wanted to embed clutter inside of my
Gtk program.  I downloaded the gtk-clutter-0.10 binding patch and applied
it.  However I can not figure out how to get the stage/actor embedded inside
of Gtk.  Can anyone provide a simple example.

I currently have

using Gtk;
using Clutter;

public class test : Window {

  public test () {
     this.title = "Embed Clutter Inside GTK";
     this.position = WindowPosition.CENTER;
     this.set_default_size (400,400);

     //Create Clutter Stage/Actor to embed inside GTK
     Gtk.Widget clutter_box = new GtkClutter.Embed ();

     //Add a button that will start the clutter animation
     var sbutton = new Button.with_label ("Start");
     //sbutton.clicked.connect ( () => {
     //   //need to start clutter animation some how
     //});

     //create a vbox with embed clutter on top and button on bottom
     var vbox = new VBox (true, 5);
     //vbox.add(clutter_box);
     vbox.add(sbutton);

     this.add (vbox);
  } //test

  public static int main (string[] args) {
     Gtk.init (ref args);

     var window = new test ();
     window.destroy.connect (Gtk.main_quit);
     window.show_all ();

     Gtk.main ();
     return 0;
  } //main
} //test

It compiles just fine, but when I run the program I get the errors:

(test:3029): Clutter-WARNING **: Unable to create a new stage: the glx
backend does not support multiple stages.

(test:3029): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(test:3029): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion
`G_TYPE_CHECK_INSTANCE (instance)' failed


Is that my computer causing the errors or my code?  Thanks for any help you
can provide, it will be most appreciated.  Also if I am asking this in the
wrong place I apologize.
