This directory contains simple GtkGLExt application examples using
libglade.

To build examples, type

  $ gcc -o simple simple.c \
      `pkg-config --cflags --libs gtkglext-1.0 libglade-2.0`

  $ gcc -o share-lists share-lists.c \
      `pkg-config --cflags --libs gtkglext-1.0 libglade-2.0`

Note that "configure_event" signal handlers are connected with
after="yes" (g_signal_connect_after()), because users'
"configure_event" signal handers are connected before
gtk_widget_set_gl_capability() by glade_xml_signal_autoconnect().
