Block wxPython app under an OS

Is there a way to block an app under an OS. Like I wanna block an app to run under Mac OS X. Doing if platform.system() == ‘Darwin’: return False in OnInit of wx.App does not work. Any other ideas?

Check either

sys.platform == “darwin” :

or

wx.Platform == ‘WXMAC’

Check this after creating the App, then pop up a wx.MessageBox saying “This app is not supported on MacOS”, and call sys.exit(0) instead of App.MainLoop(). Raising a RuntimeError during OnInit will also take down the program, but ill-advised - if this is something you’re going to distribute, you should at least show the user a more helpful message than a Python traceback.

I have managed to kill the app if the operating system is the Mac OS X. I am returning False in OnInit of wx.App if sys.platform == ‘darwin’. I also show a wx.MessageBox() to the user. And after the button OK is pressed, the app itself returns a string ‘OnInit returned false, exiting…’. However, if I kill the app by sys.exit(0), I get no nagging string. Is it possible to suppress the string ‘OnInit returned false, exiting…’ somehow? As a side note: the string should really say ‘OnInit returned False, exiting…’.

Catch the SystemExit exception that is being raised and do something different.

Robin, please fix the string ‘OnInit returned false, exiting…’ to ‘OnInit returned False, exiting…’. If this string comes from wxWidgets, then please fix it in wxWidgets.
