Hi,

API-wise this now looks like it could go to CCC.
I have not reviewed the implementation yet but that
should not stop the CCC from being submitted as final.

Perhaps the only concern I have is around AppHidden/Appreopened
where I am not convinced that it is the right thing to not send normal
window events indicating the window is hidden. What would the harm
be in sending such events so that apps that aren't able to use these
Mac-specific events because they pre-date these APIs don't get a
notification which seems to mean the same thing to me.
That could be an implementation detail or something we can
refine later in an targeted CCC if needed.

The AppContext issue is an implementation issue and we can discuss
it later but the reason other places do not check is it never used to
return null. Now it can. So do we really want to add more places
that we need to fix ? In other words I don't think the fix is going
to be to revert to it not returning null, so you are going to have
to deal with it directly here.

Desktop.java looks fine now. Moving on to the other API classes

Top-level question :
Why are AppEvent and TaskBar in java.awt and not java.awt.desktop ?
Agreed on AppEvent, but Taskbar is placed in java.awt on purpose to make it adjacent with Desktop and SystemTray.
And AppEvent seems to use a lot of nested classes.
If they were in java.awt.desktop then they could be top-level classes
without creating too much clutter. I don't think it matters that 'this
is how the com.apple APIs were done' - people need to recode anyway


AppEvent.java :
more wildcards ..
   28 import java.awt.desktop.*;

I notice the docs in this file (and perhaps more I have yet to see)
reference types without @code :-
eg :
  * Constructs a FilesEvent
* Constructs an OpenFilesEvent
..
  * Get the URI the app was asked to open
  146          * @return the URI

and more. Not essential I suppose but preferable.

   69         public List<File>  getFiles() {
   70             return files;
   71         }

Is there any need to return a copy for any of these ?

   95          * Gets the search term. The platform may additionally provide 
the search
   96          * term that was used to find the files. This is for example the 
case
   97          * on Mac OS X, when the files were opened using the Spotlight 
search
   98          * menu or a Finder search window.
   99          *
  100          * This is useful for highlighting the search term in the 
documents when
  101          * they are opened.
  102          * @return the search term used to find the files

Could we say "optionally" instead of "additionally"
and make clear that it may be "null"

a very long line :-

209      * Event sent when the application has become the foreground app, and 
when it has resigned being the foreground app.

And "resigned" is a voluntary term. If something else is placed into the foreground the
this app may not get asked if it wants to allow that.
Maybe instead say "and when it is no longer the foreground app."

Done.
Also is there anything we can (or should) say about how some of these events interact ?

eg, if a foreground app is hidden does only the appHidden listener get called ?

Both listeners could be called, it's already mentioned here:
* Called when the hidden app is shown again (but not necessarily brought to
     * the foreground).
     *
     * @param e event
     */
    public void appUnhidden(final AppHiddenEvent e);

BTW the term 'unhidden' makes sense if the app was previously 'hidden' but less so
if the app is being newly shown.


  /**
  252          * The system does not provide a reason for a session change.
  253          */
  254         @Native
  255         public static final int REASON_UNSPECIFIED = 0x0;
  256

I think we should use an enum here.


Also unless there is a reason I have not yet come across, as many as possible
of these classes should be marked 'final'


Taskbar.java :

One meta-concern I have here is that it seems to have a very blurry distinction
with existing API :
https://docs.oracle.com/javase/8/docs/api/java/awt/SystemTray.html
https://docs.oracle.com/javase/8/docs/api/java/awt/TrayIcon.html

Aren't both of these APIs dealing with the same area ?

Should we really add this new class or tweak system tray as needed ?
On Windows they dealing in the same area with taskbar, but on Mac OS SystemTray and Taskbar(Dock) are separated. So I prefer to left it as it is.

/**
  112      * Stops displaying the progress.
  113      */
  114     @Native
  115     public static final int STATE_OFF = 0x0;

Another case where an enum could be used.


   sun.awt.AppContext context = sun.awt.AppContext.getAppContext();

these days this sometimes can return null ..

There are many usages of getAppContext() without null check all over our code, so I think that this should be fixed under a separate bug.
AppForegroundEvent :
* @param e the app became foreground notification.

I am not entirely sure what that means or even what it
should say, perhaps because  AppForegroundEvent does not
have any fields.
How about
"@param e an event indicating that the receiving application is now the foreground 
app"

   30 /**
   31  * Implementors are notified when the app is hidden or shown by the user.
   32  * This notification is helpful for discontinuing a costly animation if 
it's not visible to the user.
   33  */
   34 public interface AppHiddenListener extends SystemEventListener {
  .. we already can get notification when a window is hidden.
Can I assume that this event indicates *all* windows are hidden and
each hidden window still gets its hidden event ? And that there is
no guarantee of order of delivery ?

It is a Mac specific hide, Cmd+H, or right click in dock and select hide. All windows are hidden, but in this case windows may not receive such notifications and only gets AppHiddenEvent.

/**
   31  * Implementors receive notification when the app has been asked to open 
again.
   32  *
   33  * This notification is useful for showing a new document when your app 
has no open windows.
   34  */
   35 public interface AppReopenedListener extends SystemEventListener {

So .. this means something more than that the windows have been hiddent ?
Does it mean that all windows have been disposed() but the app is still running 
?
Is this the case when the system menu bar can be used be the user to request
a new window ? Can you please give an example.

It is another Mac specific feature, it does exactly how it described.
You can have no windows(not even created), no system menu bar and some running thread, AppReopenedListener will be called on click in dock icon or on double click on the application executable.

I am sure you need all of them but it is still recommended practice.

Also I do not see where you are adding the new package to the ones for
which javadoc is generated.
This would be an edit to $TOPLEVEL/common/CORE_PKGS.gmk

I am focusing first on the API part of this so you can finalize the CCC.

Or better

These should all be @since 9

I am surprised to see this changed .. we are making the opposite update 
elsewhere.
All the cases you have changed need to be changed back.

Does that link work ? The referenced class is in a different package.
I am fairly sure that in all such cases you need to fully qualify the class 
using the package.

I believe that javac should run doclint as part of the JDK build so you should 
examine the output/logs.

686      * @param aboutHandler the handler to respond to the

seems like line 686 is incomplete. Same for line 704 :

  813         checkActionSupport(Action.APP_QUIT_STRATEGY);
  814         peer.setQuitStrategy(strategy);


Some of the actions discuss permissions and others do not.


Shouldn't this say something about permissions ? You do need permission to
exit the VM, so should you be able to set a QuitStrategy if you don't have
such permission ??



More later ..

What do you think about accompanying the application events with a flag containing the extended information that may be provided by various native platforms? For example, the session events may provide a reason on the Windows platform. Also this may add flexibility that allows to support new features in the future.

Hi Semyon,

Yes, it is just LOCK/UNLOCK for now, because it is the most common scenario of desktop usage.

Do you mean that we should consider remote desktop logins too? Something like:

         if (wParam == WTS_CONSOLE_CONNECT
                  || wParam == WTS_CONSOLE_DISCONNECT
                  || wParam == WTS_REMOTE_CONNECT
                  || wParam == WTS_REMOTE_DISCONNECT
                  || wParam == WTS_SESSION_UNLOCK
                  || wParam == WTS_SESSION_LOCK) {

              BOOL activate = wParam == WTS_CONSOLE_CONNECT
                                || wParam == WTS_REMOTE_CONNECT
                                || wParam == WTS_SESSION_UNLOCK;
env->CallStaticVoidMethod(clzz, AwtToolkit::userSessionMID,
                                                activate
                                                ? JNI_TRUE
                                                : JNI_FALSE);
          }

That's seems better to me.
Or if you refer to WTS_SESSION_LOGOFF, then it seems useless for us, AFAIK only services will receive this notification, and anyway all apps the user was running are already killed by this time.
Is it possible to use WM_QUERYENDSESSION for Action.APP_SUDDEN_TERMINATION?

Hi Alexander,

          break;
      }

So only the WTS_SESSION_UNLOCK is propagated to java as a session act/deact and other messages just ignored?

Other messages:
#define WTS_CONSOLE_CONNECT 0x1
#define WTS_CONSOLE_DISCONNECT 0x2
#define WTS_REMOTE_CONNECT 0x3
#define WTS_REMOTE_DISCONNECT 0x4
#define WTS_SESSION_LOGON 0x5
#define WTS_SESSION_LOGOFF 0x6
#define WTS_SESSION_LOCK 0x7
#define WTS_SESSION_REMOTE_CONTROL

some of them seems to me more suitable to be chosen as the session act/deact event. Could you comment that for me?

Hi Phil,

Can someone explain why this is needed given the existing support of GraphicsDevice.setFullScreenWindow(Window) ?

GraphicsDevice.setFullScreenWindow is used for an exclusive full screen mode. Mac OS has another option to create a virtual desktop with provided window in it.
You can switch between them by three-finger horizontal swipe.

Why does it have to be a RootPaneContainer ? Why is this tied to Swing ? This appears to narrow it to JDialog and JWindow.
It reuses swing code to set native windows style bits.

Needs @implNote

There seems to be lots of missing SecurityException tags given all the checkAWTPermission() calls. is checkAWTPermission() really the right call for all of these actions ? Does it "cover" being able to delete files and quit the app ? I am not sure it is
correct in all cases.

And also there are missing @since tags.

 939     public boolean browseFileDirectory(File file) {

So what happens if there is no "support" for this ? Exception or "false" ? Are you comfortable that all these APIs that return "true" if successful are implementable on all platforms. i.e I mean that does the platform return
a value you can pass on as success/failure.
