.SH DESCRIPTION
The QAccessible class provides enums and static functions relating to accessibility.
.PP
Accessibility clients use implementations of the QAccessibleInterface to read information an accessible object exposes, or to call methods to manipulate the accessible object.
.PP
See the plugin documentation for more details about how to redistribute Qt plugins.

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QRESULT QAccessible::queryAccessibleInterface ( QObject * object, QAccessibleInterface ** iface )\fC [static]\fR"
Sets \fIiface\fR to point to the implementation of the QAccessibleInterface for \fIobject\fR, and returns QS_OK if successfull, or sets \fIiface\fR to 0 and returns QE_NOCOMPONENT if no accessibility implementation for \fIobject\fR exists.
.PP
The function uses the classname of \fIobject\fR to find a suitable implementation. If no implementation for the object's class is available the function tries to find an implementation for the object's parent class.
.PP
This function is called to answer an accessibility client's request for object information. You should never need to call this function yourself.
.SH "void QAccessible::updateAccessibility ( QObject * object, int control, Event reason )\fC [static]\fR"
Notifies accessibility clients about a change of the accessibility information of \fIobject\fR.
.PP
\fIreason\fR designates the cause of this change, e.g. ValueChange when the position of e.g. a slider has been changed. \fIcontrol\fR is the ID of the child element that has changed. When \fIcontrol\fR is null, the object itself has changed.
.PP
Call this function whenever the state of your accessible object or one of it's subelements has been changed either programmatically (e.g. by calling QLabel::setText() ) or by user interaction.
.PP
If there are no accessibility tools listening to this event, the performance penalty for
calling this function is minor.
