Re: [Pyobjc-dev] Multiple Document App Template

[Jack J. <Jac...@or...>]

I've thought about what you see for a long time, but I can't figure out 
what is going on, it doesn't make sense.

Let me first explain what I thought was going on when Bob mentioned the 
missing Apple event.

My reasoning was that what causes the untitled window to open in an 
ObjC application is the "open application" event that the finder sends 
when you double-click the app. If this is the case then your PyObjC 
application will indeed not open an untitled window, because the "open 
application" Apple Event will be sent to the stub application which 
fires up Python, not to Python (and, hence, it will be lost to your 
PyObjC code).
It should be simple to test whether this reasoning is correct: if you 
start an ObjC application from the Terminal window with 
..../xxx.app/Contents/MacOS/xxx it will not open an untitled window.

But your findings makes things more complicated. The only thing I can 
imagine is that NSApplicationMain() looks at argv and if argv isn't the 
-psn_xxxx magic option it knows it has been started from the command 
line, and uses argv to construct either an Open Application message 
(argv empty) or an Open Doc message (argv non-empty).

Again, this is easy to test: if it's true then the test above failed 
(an untitled window was opened), but if you start from the Terminal 
with a -psn_xxxx option the window will not be opened. And if you pass 
a filename that file will be opened.
