Fwd: [PyQt] QAction menu questions

Is there an example someone could point me to that demonstrates how to specify the About Menu and item name, changing them from "Python" and "About Python to "MyApp" and "About MyApp?"

My searches are coming up empty.

Thanks in advance!

Subject: [PyQt] QAction menu questions

How does one set an app's About (help) menu to display the app's name, rather than "Python."

In addition, I'd like to have the menu's aboutAction item and the exitAction item display my app name as well. They currently display "About Python" and "Quit Python," respectively.

Interestingly, the aboutQtAction displays the string specified in the QAction declaration.

Is this an OS-specific issue? I'm testing on OSX. See the attached example program, simplified from .../examples/menus.py.

Thanks!
Scott
