Re: Using gtk-vnc with XenServer 6.2

[Pugnator <ookami mail ru>]

It works for me with example gvncviewer if I disabled my implementation 
and only used ssh tunnel created by my app. But my implementation is 
rather simple and straightforward.
I can't get what can cause such behavior. No cairo canvas is created for 
new XenServer 6.2
It must be my error but I can't get where.
GUI.vnc is GtkFrame with no childs

void vnc_open (char *vnc_port)
{
    GtkWidget *vnc;
    vnc = vnc_display_new();
   if(vnc_display_open_host(VNC_DISPLAY(vnc), "127.0.0.1", vnc_port))
   {
        vnc_check_and_close(GUI.vnc);
        vnc_display_set_keyboard_grab(VNC_DISPLAY(vnc), TRUE);
        vnc_display_set_pointer_grab(VNC_DISPLAY(vnc), TRUE);
        if (!gtk_widget_is_composited(GUI.main_window))
        {
            vnc_display_set_scaling(VNC_DISPLAY(vnc), TRUE);
        }
        g_signal_connect(vnc, "vnc-disconnected",
                         G_CALLBACK(vnc_disconnected), NULL);
        gtk_container_add(GTK_CONTAINER(GUI.vnc), vnc);
        gtk_widget_realize(vnc);
    }
}
