Member Function Documentation

QRESULT QAccessible::queryAccessibleInterface ( QObject *, QAccessibleInterface ** ) [static]

void QAccessible::updateAccessibility ( QObject * object, int control, Event reason ) [static]

Call this function when the accessibility information of object is changed.

reason designates the cause of this change, e.g. ValueChange when the position of e.g. a slider has been changed. control is the ID of the child element that has changed. When control is null, the object itself has changed.

Emit this signal 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.

If there are no accessibility tools listening to this event, the performance penalty for calling this function is minor.
