38 * The GLXSDOps structure contains the GLX-specific information for a given
39 * OGLSurfaceData. It is referenced by the native OGLSDOps structure.

41 * Window window;
42 * For onscreen windows, we maintain a reference to that window's associated
43 * XWindow handle here. Offscreen surfaces have no associated Window, so for
44 * those surfaces, this value will simply be zero.
45 *
46 * Drawable xdrawable;
47 * If a GLXDrawable has a corresponding X11 Drawable, it is stored here. For
48 * example, each GLXWindow has an associated Window and each GLXPixmap has an
49 * associated Pixmap. GLXPbuffers have no associated X11 Drawable (they are
50 * pure OpenGL surfaces), so for pbuffers, this field is set to zero;
51 *
52 * GLXDrawable drawable;
53 * The native handle to the GLXDrawable at the core of this surface. A
54 * GLXDrawable can be a Window, GLXWindow, GLXPixmap, or GLXPbuffer.
55 *
56 * AwtGraphicsConfigData *configData;
57 * A pointer to the AwtGraphicsConfigData under which this surface was
58 * created.
