java - Event Handling for Pie Chart -

i have created javafx pie chart , want when user clicks on slice of pie. following tutorial:

for (final piechart.data data : chart.getdata()) { data.getnode().addeventhandler(mouseevent.mouse_pressed,     new eventhandler<mouseevent>() {         @override public void handle(mouseevent e) {             caption.settranslatex(e.getscenex());             caption.settranslatey(e.getsceney());             caption.settext(string.valueof(data.getpievalue()) + "%");          }     }); 

i getting these error warnings prior compile: on ".addeventhandler"

bound mismatch: generic method addeventhandler(eventtype<t>, eventhandler<? supert>) of   type node not applicable arguments (integer, new eventhandler<mouseevent>  (){}). inferred type mouseevent&event not valid  substitute bounded parameter <t extends event> 

on "eventhandler"

bound mismatch: type mouseevent not valid substitute bounded parameter   <t extends event> of type eventhandler<t> 

does have insights why getting these errors?

the addeventhandler() method takes 2 parameters: 1 of type t, , 1 has super class t. gave eventhandler , integer. since integer not super class of eventhandler, exception.

my guess you're accidentally using java se's mouseevent instead of java fx's mouseevent.
