Twisted Tk swallows errors in ::tk::mac::Quit on MacOS X

[r_owen]

The Twisted event loop, when used with Tkinter silently swallows exceptions raised in the ::tk::mac::Quit command (thus this is only an issue on MacOS X).

The problem does not show up when using Tk's own event loop. See attached example, which includes a flag to toggle twisted on/off.

My setup:

• Mac OS X 10.7.4
• 64-bit python.org Python 2.7.3
• ActiveState Tcl/Tk ActiveTcl8.5.11.1.295590-macosx10.5-i386-x86_64-threaded
• Twisted 12.0.0

From the API documentation for tksupport:

When using Aqua Tcl/Tk on Mac OS X the standard Quit menu item in your application might become unresponsive without the additional

fix

| root.createcommand("::tk::mac::Quit", reactor.stop)
