How to get notified when InDesign Application hides (Mac)

Feb 2, 2012 9:54 AM

Hi!

 

I need to modify the behavior of a secondary process  I launch in my plugin when the InDesign app hides (from the dock or using the cmd+h key combination).

I was trying to add an observer and callback using the Notification Center (local) though I can't find a way to get the main or key window to do so.

 

Anyone has any pointers as how I can do this?

 

Thanks!

    I'm not sure what you mean with Notification Center (local).

    Sounds like an OSX specific thing.

     

    Instead, attach an InDesign IObserver to the kAppBoss, protocol IID_IAPPLICATION.

    You'll receive kApplicationSuspendMsg and kApplicationResumeMsg.

     

    Hth,

    I only receive the kApplicationSuspendMsg (InDesign CS3), what could I be missing?

     

    In the startupshutdown i have:

     

    obsv = (IObserver*) CreateObject (kAppObserverBoss, IID_IOBSERVER);

    //attach app messages observer

    InterfacePtr<IApplication> iApp (gSession->QueryApplication ());

    InterfacePtr<ISubject> iAppSubject (iApp, IID_ISUBJECT);

    if(iAppSubject)

              iAppSubject->AttachObserver(obsv , IID_IAPPLICATION);

     

    and in the update of the appObserver I have:

     

     

    do {

                        if( theChange.Get ()== kAppBoss)

                        {

                                  if(protocol.Get()==IID_IAPPLICATION){

                       if(theChange==kApplicationSuspendMsg){

                                                           fprintf(stderr, "kApplicationSuspendMsg\n");

                       }

     

                                            if(theChange==kApplicationResumeMsg){

                                                      fprintf(stderr, "kApplicationResumeMsg\n");                  

                                            }

                                  }

                        }

    }while(kFalse);

    I have another problem, I think what I need instead is to make my secondary process (with gUI) nest as a child window to indesign's main window, because if I try to use this messages, I'll always receive them when I change focus to the separate window.

    As Dirk rightly pointed out, you need to place an observer in the kAppBoss and observe on the IID_IAPPLICATION protocol.

     

    What you should do is just place an interface as an addin in the kAppBoss and give it an implementation (you don't need to create a observer boss class as you have done).

     

    In startup call the autoattach of your observer, for ex

      InterfacePtr<IApplication> app(gSession->QueryApplication());

     

      InterfacePtr<IObserver> iMyObserver(app, IID_IMYOBSERVER);

                        iMyObserver->AutoAttach();

     

    In the autoattach method of your implementation class, remember to pass your observers interface ID to the attachobsever method of the ISubject

    for ex

    AttachObserver(this, IID_IAPPLICATION, IID_IMYPOBSERVER);

     

    Then in the update method you will get properly notified of the suspend and resume of application

     

    This should fix your problem.
