\class QAccessibleBridge
|
|
\brief The QAccessibleBridge class is the base class for
|
|
accessibility back-ends.
|
|
|
|
\ingroup accessibility
|
|
|
|
Qt supports Microsoft Active Accessibility (MSAA), Mac OS X
|
|
Accessibility, and the Unix/X11 AT-SPI standard. By subclassing
|
|
QAccessibleBridge, you can support other backends than the
|
|
predefined ones.
|
|
|
|
Currently, custom bridges are only supported on Unix. We might
|
|
add support for them on other platforms as well if there is
|
|
enough demand.

This function is called by Qt at application startup to set the

client using object navigation.

This function is called by Qt to notify the bridge about a change
|
|
in the accessibility information for object wrapped by the given
|
|
\a interface.
|
|
|
|
\a reason specifies the cause of the change. It can take values
|
|
of type QAccessible::Event.
|
|
|
|
\a child is the (1-based) index of the child element that has
|
|
changed. When \a child is 0, the object itself has changed.

\brief The QAccessibleBridgePlugin class provides an abstract

base for accessibility bridge plugins.

\ingroup plugins

Writing an accessibility bridge plugin is achieved by subclassing

this base class, reimplementing the pure virtual functions keys()
|
|
and create(), and exporting the class with the
|
|
Q_EXPORT_PLUGIN2() macro.
