AccessibleEventNotifier::TClientId comphelper::AccessibleEventNotifier::registerClient ( )

static

registers a client of this class, means a broadcaster of AccessibleEvents

No precaution is taken to care for disposal of this component. When the component dies, it must call <member>revokeClient</member> or <member>revokeClientNotifyDisposing</member> explicitly itself.

sal_Int32 comphelper::AccessibleEventNotifier::removeEventListener ( const TClientId  _nClient, const css::uno::Reference< css::accessibility::XAccessibleEventListener > &  _rxListener  )

static

revokes a listener for the given client

Parameters

_nClient

the id of the client for which a listener should be revoked

Returns

the number of event listeners currently registered for this client

void comphelper::AccessibleEventNotifier::revokeClient ( const TClientId  _nClient )

static

revokes a broadcaster of AccessibleEvents

Note that no disposing event is fired when you use this method, the client is simply revoked. You can for instance revoke a client if the last listener for it is revoked, but the client itself is not disposed.
When the client is disposed, you should prefer <member>revokeClientNotifyDisposing</member>

Any possibly pending events for this client are removed from the queue.

Any other possibly pending events for this client are removed from the queue

Parameters

_nClient	the id of the client which should be revoked
_rxEventSource	the source to be notified together with the <member scope="com.sun.star.lang">XComponent::disposing</member> call.
