Pass an argument to a bundle application under MacOSX

[Matt Connolly]

Ah. After reading my message, I didn't fully explain the idea. Sorry.

The application could tell at launch time of there was a document  =

open requested. For traditional Carbon applications, the application  =

receives an event at launch time from the system, "OAPP" for open the  =

application, and "ODOC" for open a document. These are handled by  =

these virtual functions in the mac implementation:

(in wxApp)
     virtual void         MacOpenFile(const wxString &fileName) ;
     virtual void         MacNewFile() ;

The default implementation for "MacNewFile" does nothing.

The default implementation for "MacOpenFile" goes to the wxDocManager  =

class to open the document.

I guess the major draw back to this approach is that you need to then  =

initialise your application and then wait for the appropriate event  =

from the operating system ( OAPP or ODOC ) to determine which mode  =

your application should run in.

As far as the argument goes, you'd have to store that in the document  =

and read it yourself. I'm not aware of any other ways to pass command  =

line arguments to Mac OS X applications.

Hope that helps. Sorry if it's not the perfect solution.


Cheers,
Matt
