How is garbage collect done in wxPython? Is there a function or method call
that will perform garbage collection.
It appear that only when my app is minimized that garbage collection is
done. I would like to do it more often.

Remove all my children components and optionally
destroy them.

while self.GetSizer().Remove(0):
pass
if destroy:
self.DestroyChildren()
When I use this on my panel, it appears that instead of Remove(0)
returning a false if the item isn't found, it causes an assertion in the
wx core. Here's the traceback:
Try it like this:
def removeChildren(self, destroy=1):
sizer = self.GetSizer()
while sizer.GetChildren():
sizer.Remove(0)
if destroy:
self.DestroyChildren()

Thanks Joshua. Sorry about the unrelated thread. I was rushing.

See Python's `gc' module.
And..., could you please avoid piggy-backing on unrelated threads like that?
It's really... bothersome....
Thanks

There are a number of factors. Normally Python objects are cleaned up when their reference count drops to zero. Python's GC kicks in periodically to try and collect situations when there are unattached circular references, but I think that it doesn't work if there are references held from C++ objects... Then there is the memory allocated by the wx C++ objects themselves, and if all goes well then that is freed when the objects are deleted by whatever means. *But*, what you are probably seeing happening when you minimize your app is totally unrelated and is Windows moving parts of the app's process map out to virtual memory pages, since similar memory reduction often happens when minimizing non-Python apps too.
