Member Function Documentation
QAccessibleStateChangeEvent::QAccessibleStateChangeEvent(QObject * object, QAccessible::State state)
Constructs a new QAccessibleStateChangeEvent for object. The difference to the object's previous state is in state.
QAccessibleStateChangeEvent::QAccessibleStateChangeEvent(QAccessibleInterface * iface, QAccessible::State state)
QAccessible::State QAccessibleStateChangeEvent::changedStates() const
Returns the states that have been changed.
Be aware that the returned states are the ones that have changed, to find out about the state of an object, use QAccessibleInterface::state().
For example, if an object used to have the focus but loses it, the object's state will have focused set to false. This event on the other hand tells about the change and has focused set to true since the focus state is changed from true to false.
