Well, since these are just exceptions, a simple try... except block would be fine, and you can even figure out the reason for the exception. Here is what I'd do:
- when you create your Tkinter main window, initialize an attribute that you'll use to see if the application has quit, e.g mainwin.hasQuit = False
- rewrite doquit this way:
def doquit():
if os.access('recalc.tmp', os.F_OK):
os.remove('recalc.tmp')
mainwin.hasQuit = True
pygame.quit()
- rewrite your custom event loop this way:
while 1:
gameLoop()
pygame.time.wait(10)
try:
mainwin.update()
except TclError:
if not mainwin.hasQuit:
raise
And: (1) your problem should go away; (2) the "real" exceptions you may get from Tkinter windows should not passed unnoticed.
I adapted your suggestion slightly, and my final event loop looks like this:
while not mainwin.hasQuit:
try:
gameLoop()
except pygame.error:
if not mainwin.hasQuit:
raise
pygame.time.wait(10)
try:
mainwin.update()
except Tkinter.TclError:
if not mainwin.hasQuit:
raiseThat seems to work perfectly. Thanks, Eric!
Incomplete, but very useful: http://www.pythonware.com/library/tkinter/introduction/index.htm
But the best reference documentation you'll ever find is the tcl/tk man pages, on-line here: http://www.tcl.tk/man/tcl8.4/TkCmd/contents.htm
It unfortunately requires to know how to convert the tcl/tk syntax to Python/Tkinter syntax, but it is actually quite easy (mainly read "option=value" when the tcl/tk documentation says "-option value")
Ah, yes, I had managed to find the pythonware.com pages in my travels, and they proved quite helpful. Good to know about the man pages, too. (When I'm starting on a language feature, though, I usually find I learn a lot more from worked examples than from straight command information. I have friends who are just the opposite, so I suppose it's just a learning styles thing.)
wxPython seems to be highly regarded. I might experiment with that for my next project, and see which framework I like the best. Thanks again.
