netbeans-antlr pluging, click on the current editor event

[Peter Cheung]

Dear Sir/Madam
     I want to enhance my netbeans-antlr plugin 
(https://gitlab.com/quantr/toolchain/netbeans-antlr) by allowing people to 
click on the editor and highlight the token in the tree view. How can I 
subscribe the click event of the current editor?


Thanks
