Re: Starting XUL from JavaXPCOM

Hi,

I'm actually not explicitly defining AWT or Swing, I'm just calling the 
code below.  Does this implement Swing under the hood?  I dont really 
want to have to embed XUL inside Swing windows.  Ideally I would just 
like to start XUL as if it was xulrunner with the ability to call 
javascript from Java, or at least open windows.

I may have confused things slightly by presuming too much there, but the 
only reason I wanted to get inside the main gui event thread was because 
I assumed you would need to be in there to play with xpcom.  It seems 
that whatever thread initializes the XPCOM embedding has to be the 
thread that calls appShell.run(), and as such, I'm precluded from 
playing with xpcom any more once run() has been called.  All I really 
want to do, is open new windows :P

Any further tips you have would be greatly appreciated.  I hope this 
makes things a bit clearer... I'm still struggling to get my head round 
how all this fits together...

        Mozilla moz = Mozilla.getInstance();
       
        // initialize the embedding
        moz.initEmbedding(grePath, grePath, locProvider);
       
        // component manager
        componentManager = moz.getComponentManager();
       
        appShell = (nsIAppShell) componentManager.createInstance(
                    NS_APPSHELL_CID, null, nsIAppShell.NS_IAPPSHELL_IID);

        appShell.create(null, null);
        appShell.spinup();
   
        // get service manager
        serviceManager = moz.getServiceManager();
       
        
        // Now we need to get the @mozilla.org/toolkit/app-startup;1 
service:
       // we only use this for its nsIWindowCreator2
        nsIAppStartup appStartup = 
(nsIAppStartup)serviceManager.getServiceByContractID("@mozilla.org/toolkit/app-startup;1", 
nsIAppStartup.NS_IAPPSTARTUP_IID);
       
        // get the window creator interface to the app-startup service
        windowCreator = 
(nsIWindowCreator)appStartup.queryInterface(nsIWindowCreator.NS_IWINDOWCREATOR_IID);

        // get the window-watcher service
        windowWatcher = 
(nsIWindowWatcher)serviceManager.getServiceByContractID("@mozilla.org/embedcomp/window-watcher;1", 
nsIWindowWatcher.NS_IWINDOWWATCHER_IID);
       
        // set our window creator (the app-startup) service
        windowWatcher.setWindowCreator(windowCreator);


        openWindow("chrome://rmyapp/content/launcher.xul", "launcher");
       
        appShell.run();
