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

.TP
\fCQAccessible::Description\fR - A short text describing the object
.TP
\fCQAccessible::Value\fR - The value of the object

.TP
\fCQAccessible::DefaultAction\fR - The default method to interact with the object
.TP
\fCQAccessible::Accelerator\fR - The keyboard shortcut that executes the default action
.SH MEMBER FUNCTION DOCUMENTATION
.SH "bool QAccessible::isActive ()\fC [static]\fR"
Returns TRUE if an accessibility implementation has been requested, during the runtime of the application, otherwise returns FALSE.
.PP
Use this function to prevent potentially expensive notifications via updateAccessibility().
.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 \fCQS_OK\fR if successfull, or sets \fIiface\fR to 0 and returns \fCQE_NOCOMPONENT\fR 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 in \fIobject\fR's accessibility information.
.PP
\fIreason\fR specifies the cause of the change, for example, ValueChange when the position of a slider has been changed. \fIcontrol\fR is the ID of the child element that has changed. When \fIcontrol\fR is 0, the object itself has changed.
.PP
Call this function whenever the state of your accessible object or one of it's sub-elements 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, but if determining
the parameters of the call is expensive you can use isActive() to
avoid unnecessary performance penalties if no client is listening.
