[GtkGLExt] Re: Help, maybe a bug in FreeBSD 5.3! (mk mk)

[mk mk <mk1g6g yahoo com cn>]

Hi, 

Problem has been fixed! It annoyed me serveral days.
Two issues should be noted. 

The first one is that the demo should be linked with
gthread-2.0 (default is xthread under FreeBSD5.3 +
Gnome2.6), or it will behave wired when resize the gl
window. 

The second one is that function
gdk_gl_drawable_make_current or
gdk_gl_drawable_gl_begin should be called only once
(the best place is in gl widget realize event
handler).  Otherwise, any following glXMakeCurrent
call which implicit called by the above two function
will be failed.

Thanks.
