Highlight Text in TextArea

SetSelection method of the TextArea is ued here to highlight the text. This method will work only if the TextArea has the focus or the “alwaysShowSelection” property of the TextArea’s textField is set to true. Since the textField is a private property, we need to extend the TextArea class and set the property inside the class.

This method is highlighting only one search term at a time. Regular expression can be used to highlight multiple matching terms
