mac os x file association - missing filename in commandline

[chkn]

I've associated a file-extension with my application (in info.plist).
When opening a document from the finder i get only something like "-psn_0_123456" in the commandLine (in initialise()).
If the application is running and i click on the document i get the correct filename in anotherInstanceStarted().

It's a process serial number, though I'm not sure what you're supposed to do with it. It should pass you the filename in anotherInstanceStarted() anyway, though, so you can ignore the -psn thing.

Code: Select all

It should pass you the filename in anotherInstanceStarted()

no, it does not (when you open a document from the finder, and the application is not running yet.)
The new jucer (3.0) , behaves the same. It does not open the file you clicked, it just checks for the character "-" in the commandLine and open the documents which were last time opened, but not that one which you clicked.

erm.. yes it does! I just tried the jucer - it works fine.

Maybe this thread is helpful:

ahh, i see (had a splash screen, added a alertBox to the Jucer to see whats going on, and so we have the same behaviour...)

But if we you use the AsyncUpdater-Method, we have also complete different behaviour on Windows (which uses the Initialise commandLine), also we have to care, because anotherInstanceStarted() on Mac is called before the async initialisation.

something like this:

Code: Select all

    void initialise (const String& commandLine)
    {
      initialiseCommandLine=commandLine;
      triggerAsyncUpdate();
    }
   
   void handleAsyncUpdate()
    {
          SplashScreen* splash = new MainSplash();
      splash->show(ApplicationName,470,200,1000,true,false);
      
        // just create the main window...
      mainWindow = new MyWindow();
      
      // do init stuff etc...

      String fileNameCommandLine=extractFileNameFromCommandLine(initialiseCommandLine);
      
      if (fileNameToOpenAfterInit.isNotEmpty())
      {
         mainWindow->openFile(fileNameToOpenAfterInit);
         fileNameToOpenAfterInit="";
      } else
      {
         if (fileNameCommandLine.isNotEmpty())
         {
            mainWindow->openFile(fileNameCommandLine);
         };
      }

    };
   
   void anotherInstanceStarted (const String& commandLine)
    {
      String fileName=extractFileNameFromCommandLine(commandLine);

      if (fileName.isNotEmpty())
      {
         if (mainWindow!=0)
         {
            mainWindow->openFile(fileName);
         } else
         {
            // Application not intialised yet!
            fileNameToOpenAfterInit=fileName;
         }
      }
    }
   
       
    bool moreThanOneInstanceAllowed()
    {
        return false;
    }

 
   
private:

   String fileNameToOpenAfterInit;
   String initialiseCommandLine;
};

Well.. I don't really know what I could do about that. The filename simply isn't available on the mac until the OS chooses to call anotherInstanceStarted(), and we have no control over when that might happen.

no problem, my solution works good.
