54
55 Qt supports Microsoft Active Accessibility (MSAA), \macos
56 Accessibility, and the Unix/X11 AT-SPI standard. By subclassing
57 QAccessibleBridge, you can support other backends than the
58 predefined ones.
59
60 Currently, custom bridges are only supported on Unix. We might
61 add support for them on other platforms as well if there is
62 enough demand.
