how fire single , double mouse click events on first (or other) item of javafx.scene.control.listview ? i want receive event this: getlistview().setonmouseclicked(mouseevent -> { switch (mouseevent.getclickcount()) { case 1: break; case 2: break; } }); there seems misunderstanding. events not fired on items of listview , on listcell s display items. listcell s may constructed dynamically , reused, there may not event target corresponding particular item. if hands on correct node, fire event using event.fireevent : node target = ... mouseevent mouseevent = new mouseevent(mouseevent.mouse_clicked, ...); event.fireevent(target, mouseevent); you find listcell s using lookupall : set<node> listcells = listview.lookupall(".list-cell"); and use listcell.getitem , listcell.getindex determine correct one. but since event listener added listview finding correct listcell may not necessary.

i have exposed port 80 in application container's dockerfile.yml mapping "80:80" in docker-compose.yml "connection refused" after "docker-compose up" , try http on port 80 on docker-machine's ip address. docker hub provided rethinkdb instance's admin panel gets mapped fine through same dockerfile.yml ("expose 8080") , docker-compose.yml (ports "8080:8080") , when start application on local development machine port 80 gets exposed expected. what going wrong here? grateful quick insight more docker experience! so in case, service containers both bound localhost (127.0.0.1) , therefore seemingly exposed ports never picked via docker-compose port mapping. configured services bind 0.0.0.0 respectively , works flawlessly. thank @creack pointing me in right direction.
