50 \brief The QAccessibleBridge class is the base class for -
51 accessibility back-ends. -
52 \internal -
53 -
54 \ingroup accessibility -
55 \inmodule QtWidgets -
56 -
57 Qt supports Microsoft Active Accessibility (MSAA), Mac OS X -
58 Accessibility, and the Unix/X11 AT-SPI standard. By subclassing -
59 QAccessibleBridge, you can support other backends than the -
60 predefined ones. -
61 -
62 Currently, custom bridges are only supported on Unix. We might -
63 add support for them on other platforms as well if there is -
64 enough demand. -

89 object, reason and child element that has changed. -
