java - Click event being fired even not clicking -

i have code fires if don't click on on page, hovering on page trigger:

event.addnativepreviewhandler(new event.nativepreviewhandler() {             @override             public void onpreviewnativeevent(event.nativepreviewevent event) {                 switch (event.gettypeint()) {                     case event.onclick:                         $(".hopscotch-bubble").fadeout(new com.google.gwt.query.client.function() {                             @override                             public void f() {                                 jsnihelper.infonotify("info", "fade out method invoked!");                             }                         });                  }             }         }); 

i not entirely sure why happens, reason?

add clickhandler on root panel called when native click event fired anywhere on page.

sample code:

import com.google.gwt.event.dom.client.clickevent; import com.google.gwt.event.dom.client.clickhandler; import com.google.gwt.user.client.ui.rootpanel;  rootpanel.get().adddomhandler(new clickhandler() {      @override     public void onclick(clickevent event) {         system.out.println("click");      } }, clickevent.gettype());
