I'm pretty sure older versions of Mac OS (pre-OS X) *did* work that way--you had to use symbolic constants to refer to known folders and not count on the exact file paths. That said, using fully-qualified paths can still be fragile, since users may move things around when you least expect it. --Dethe There's a little bit of God in every truck driver and a little bit of truck driver in every God. -- Blayne Horner ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
[Pythonmac-SIG] Opening an app from another app under different OS X versions
My wxPython application has a context sensitive help system, using
wx.html.HtmlHelpController(), which also contains a Tutorial for the
program. Users like to leave the Help window open while they are
simultaneously working in the application. To allow this, I set the Help
application up as a free-standing application that I can call from my
regular application when it is needed. (This is necessary because of issues
with menu construction.) My applications are built using py2app, so the
call I've been using looks like this:
os.system('open -a TransanaHelp.app')
This works on OS X 10.3, and it works when I'm running under Python on OS X
10.4, but I have not been able to get anything along these lines to work
under OS X 10.4 once my app has been bundled up with py2app. It's like the
Help app tries to launch, but then it immediately, and silently, shuts down.
(i.e. the Console doesn't report anything.) os.spawnv() and
os.popen2() don't work either. Does anybody have any ideas for how I can
launch a bundled wxPython app from within another bundled wxPython app on OS
X 10.4?
Thanks for your help,

Where is the help application bundled? Alongside the main app in the
same directory, or inside the main app's application bundle itself?
Perhaps it's a path issue, i.e. 'open' can't find the app to open. If
so, you may need to do some work to get a full path to the help app,
then launch it (i.e., os.system('open -a /path/to/myapp.app') ).

Re: [Pythonmac-SIG] Opening an app from another app under different OS X versions
As Kevin said, you may only need the full path to your app. It's
remotely possible you would need the full path to open as well (/usr/
bin/open). Full paths are finicky though, and you will need to know
where your application is installed, if the help application is in
the app bundle, for instance. Also, paths are different on
internationalized versions of OS X.
The right way is probably to use PyObjC and the NSWorkspace object:
from AppKit import NSWorkspace
NSWorkspace.sharedWorkspace.launchApplication_('MyApp')
For more on Workspace services, there is this article: file:///
Developer/ADC%20Reference%20Library/documentation/Cocoa/Conceptual/
Workspace/index.html
Also, when you're launching an app with open, you don't need the -a
flag, but without it you do need the path to the application.
