Hi list,
I was just wondering if it wasn't a good idea to add the with-statement
functionality to the QPainter class. If your program happens to
raise an exception while QPainter is active, QPainter.end() might
never be called and that leads to a lot of annoying error messages.
I just propose to add to methods to QPainter, like that:
def __enter__(self):
return self
def __exit__(self, info):
self.end()
return False
Then you can write code like this:
with QPainter(image) as p:
p.drawWhatever()
and you never have the problem with a dangling QPainter.
I guess someone will start yelling "but that's Python 2.5". Indeed,
it is. But well, the changes I propose are perfectly backwards-compatible,
as it only means to add to methods to a class.
Any other thoughts / ideas?
Cheers,
Martin
