java: TrayIcon right click disabled on Mac OsX -

-

i'm trying develop mac osx app provided system tray icon, after first attempt simplest code achieve noticed every apps tray icon's (both system , user apps) on mac osx (10.8) allows activate relative popup menu both left , right click on project left (mouseevent.botton1) button causes popup menu pulldown. here's code:

public class systemtraydemo {     private systemtray tray;     private trayicon tray_icon;      public systemtraydemo()     {         if (!systemtray.issupported())         {             joptionpane.showmessagedialog(null, "system tray not supported!");             return;         }         else            tray = systemtray.getsystemtray();          final popupmenu popup = new popupmenu();           menuitem exit = new menuitem("exit");          exit.addactionlistener(new actionlistener()         {             public void actionperformed(actionevent e)             {                 if (tray != null)                 {                                         tray.remove(tray_icon);                     system.exit(0);                 }             }         });          popup.add(exit);          //add tray icon         tray_icon = new trayicon(geticon("images/wifi.png"), "open documents...", popup);         tray_icon.setimageautosize(true);          try         {                         tray.add(tray_icon); // adds icon         }         catch (awtexception ex) {}     }       private image geticon(string name)     {         url _url = getclass().getresource(name);         return new imageicon(_url).getimage();     }      public static void main(string args[])     {         new systemtraydemo();     } }

but how said, through left mouse button click. during further attempt i've tried mimic behavior of tray icons of every other apps using mouselistener , firing left button event on right click event using dispatchevent() method so:

    public static void firemouseevent(component c)     {         mouseevent me = new mouseevent(c, //                     mouseevent.mouse_clicked, //                     system.currenttimemillis(), // when                     mouseevent.button1_mask, // no modifiers                     0, 0, // where: @ (10, 10}                     1, // 1 click                      true); // popup trigger          c.dispatchevent(me);     }

the event handled mouse listener trayicon class not component subclass , therefore source of mouseevent null , npe. here's mouselistener:

    class mouseadapt extends java.awt.event.mouseadapter     {          public void mouseclicked(java.awt.event.mouseevent me)         {             int button = me.getbutton();              if(button == java.awt.event.mouseevent.button3)             {                 firemouseevent(me.getcomponent());             }         }     }      try     {                     tray.add(tray_icon); // aggiungi l'icona         tray_icon.addmouselistener(new mouseadapt());     }     catch (awtexception ex) {}

sorry english, hope have ever had experience kind of projects can me. i've searched hours no luck. thank help.

edit: there's library working fix of here: https://github.com/dorkbox/systemtray

to activate [trayicon] relative popup menu both left , right click

this not possible on mac + java currently. using reflection invoke underlying triggers doesn't seem help. bug.

https://bugs.openjdk.java.net/browse/jdk-8041890

only left (mouseevent.botton1) button causes popup menu pulldown. here's code

even broken in java versions (7u79), fixed upgrade...

https://bugs.openjdk.java.net/browse/jdk-7158615

cross-platform trayicon support:

albeit off-topic, wanted add, projects use jxtrayicon accomplish fancy drop-down menus in linux/windows, etc. these cause problems on mac despite click-bug suffers today bugs with gnome3 requiring separate hack. on mac, attempt use decorated menus causes menu linger , bad experience end-user. solution settled on use awt mac, swing else. java trayicon support in dire need of rewrite. javafx claims initiative, it's staged java 9. in mean time, i'm sticking os-dependent hacks.

related tray issues other platforms

furthermore, linux distributions ubuntu have removed tray icon default in unity desktop, causing further headaches. https://askubuntu.com/a/457212/412004

in addition, transparency of icon replaced gray color on gtk/gnome or qt/kde powered desktops (both openjdk , oracle jre suffer this) https://stackoverflow.com/a/3882028/3196753 http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6453521

in addition, gnome3 powered desktops may show in wrong corner, not @ all, or may show unclickable (both openjdk , oracle jre suffer this) https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=660157 https://bugzilla.redhat.com/show_bug.cgi?id=1014448

in addition that, high-dpi screens on windows have bug draws icon incorrectly: windows 8 distorts trayicon

so in summary, state of system tray in java ok, due combination of factors quite fragmented , buggy in jdk6, jdk7 , jdk8.

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

How to call a javascript function after the page loads with a chrome extension? -

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey? (function submitaction() ). both chrome extensions , greasemonkey offer ways specify when script inject if executed. in chrome extension, you set in manifest : "content_scripts": [ { "run_at" : "document_idle", in greasemonkey compatible userscripts, set in metadata // @run-at document-end in both cases, have add script if want ensure resources loaded when function executed : document.addeventlistener('load', submitaction);
