Asphyre Sphinx 3.0.0 has been released.

[Andru]

The problem was that I couldn't find a way to extract X-window ID from Lazarus window handle to use proper GLX device. If someone knows how to do that, I can implement direct OpenGL context creation in native fashion.

For ZenGL I use this solution(but works only with GTK version of LCL, I didn't try to use Qt version of Lazarus, so ):

uses
  {$IFDEF LINUX}
  {$IFDEF LCLGTK}
  GLib, GTK, GDK,
  {$ENDIF}
  {$IFDEF LCLGTK2}
  GLib2, GTK2, GDK2, GDK2x,
  {$ENDIF}
  {$ENDIF}

// ..

{$IFDEF LINUX}
var
  widget : PGtkWidget;
  socket : PGtkWidget;
  glist : PGlist;
{$ENDIF}
begin
  {$IFDEF LINUX}
  glist := gtk_container_children( GTK_CONTAINER( PGtkWidget( Panel1.Handle ) ) );
  widget := PGtkWidget( glist.data );
  socket := gtk_socket_new();
  gtk_container_add( GTK_CONTAINER( widget ), socket );

  gtk_widget_show( socket );
  gtk_widget_show( widget );

  gtk_widget_realize( socket );
  {$IFDEF LCLGTK}
  YourTWindow := PGdkWindowPrivate( widget.window ).xwindow;
  {$ENDIF}
  {$IFDEF LCLGTK2}
  YourTWindow := GDK_WINDOW_XID( widget.window );
  {$ENDIF}
  {$ENDIF}
