Re: How can I tell consistently if accessibility is enabled?

[Li Yuan <Li Yuan Sun COM>]

Hi Timothy,

If you can call functions in X library, getting the root window's 
property will tell you if accessibility is enabled.

/*--------------example code-------------*/
    Atom AT_SPI_IOR;
    Atom actual_type;
    int actual_format;
    unsigned char *data = NULL;
    unsigned long nitems;
    unsigned long leftover;

    AT_SPI_IOR = XInternAtom (display, "AT_SPI_IOR", False);
    XGetWindowProperty(display,
                       XDefaultRootWindow (display),
                       AT_SPI_IOR, 0L,
                       (long)BUFSIZ, False,
                       (Atom) 31, &actual_type, &actual_format,
                       &nitems, &leftover, &data);
/*---------------end of example----------------*/

If data is not NULL, at-spi-registryd has been started, which means 
accessibility is enabled.

Thanks,
Li
