49 Qt supports Microsoft Active Accessibility (MSAA), \macos-
50 Accessibility, and the Unix/X11 AT-SPI standard. By subclassing-
51 QAccessibleBridge, you can support other backends than the-
52 predefined ones.-
53-
54 Currently, custom bridges are only supported on Unix. We might-
55 add support for them on other platforms as well if there is-
56 enough demand.-
