Accessibility, and the Unix/X11 AT-SPI standard. By subclassing QAccessibleBridge, you can support other backends than the predefined ones.</p> <p>Currently, custom bridges are only supported on Unix. We might add support for them on other platforms as well if there is enough demand.</p> </div> <p><b>See also </b><a href="qaccessible.html">QAccessible</a> and <a href="qaccessiblebridgeplugin.html">QAccessibleBridgePlugin</a>.</p> <!-- @@@QAccessibleBridge --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$~QAccessibleBridge[overload1]$$$~QAccessibleBridge --> <h3 class="fn"><a name="dtor.QAccessibleBridge"></a>QAccessibleBridge::<span class="name">~QAccessibleBridge</span> ()<tt> [virtual]</tt></h3> <p>Destroys the accessibility bridge object.</p> <!-- @@@~QAccessibleBridge --> <!-- $$$notifyAccessibilityUpdate[overload1]$$$notifyAccessibilityUpdateintQAccessibleInterface*int --> <h3 class="fn"><a name="notifyAccessibilityUpdate"></a><span class="type">void</span> QAccessibleBridge::<span class="name">notifyAccessibilityUpdate</span> ( <span class="type">int</span> <i>reason</i>, <span class="type"><a href="qaccessibleinterface.html">QAccessibleInterface</a></span> * <i>interface</i>, <span class="type">int</span> <i>child</i> )<tt> [pure virtual]</tt></h3> <p>This function is called by Qt to notify the bridge about a change in the accessibility information for object wrapped by the given <i>interface</i>.</p> <p><i>reason</i> specifies the cause of the change.
