49 accessibility back-ends.-

52 \ingroup accessibility-

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.-
