If you assign an event to a control, an object registers itself internally as a "Listener" for a specific control event. To do this, the object must use a specific interface, for example the XFocusListener Interface, so that it can react to focus events. When the event occurs, the control then invokes a special method of the Listener interface when the control receives the focus. The internally registered object then invokes the JavaScript or $[officename] Basic code, which was assigned to the event.</paragraph> +<paragraph role="paragraph" id="par_id3156410" xml-lang="en-US">The HTML filter now uses precisely these listener interfaces and method names so that it can import and export events as desired.
