You can also mirror events on a text block, or on a portion of a text block, to an event dispatcher. First, create an
EventDispatcher instance and then assign it to the eventMirror property of a TextElement instance. If the text block
consists of a single text element, the text engine mirrors events for the entire text block. If the text block consists of
multiple text elements, the text engine mirrors events only for the TextElement instances that have the eventMirror
property set. The text in the following example consists of three elements: the word "Click", the word "here", and the
string "to see me in italic". The example assigns an event dispatcher to the second text element, the word "here", and
adds an event listener, the clickHandler() method. The clickHandler() method changes the text to italic. It also
replaces the content of the third text element to read, "Click here to see me in normal font!".
