(first attribute of None). See GLX 1.3 spec.glconfig : a GdkGLConfig.

Returns the GdkWindow associated with glwindow.
Notice that GdkGLWindow is not GdkWindow, but another
GdkDrawable which have an associated GdkWindow.glwindow : a GdkGLWindow.
Returns : the GdkWindow associated with glwindow.

Set the OpenGL-capability to the window.
This function creates a new GdkGLWindow held by the window.

Returns : the GdkGLWindow used by the window if it is successful,
NULL otherwise.

Returns whether the window is OpenGL-capable.window : a GdkWindow.
Returns : TRUE if the window is OpenGL-capable, FALSE otherwise.

Returns the GdkGLDrawable held by the window. In fact, this is macro
that casts the result of gdk_window_get_gl_window to GdkGLDrawable.
