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.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
