RE: [Pywinauto-users] Resource leak in ListViewWrapper

Hi Mark,

Thanks for your fast answer. As you suggest, until you release an updated
version, I will override Application.RecordMatch.

Best regards

Christophe

I am trying to research this.

First of all it happens anytime that a control is resolved - nothing
it seems to do with listview methods - you just see it more for more
complicated controls because...

I am storing all the information on a window once it matches!

You can disable this completely (and it should be disabled completely
for now by changing the Application.RecordMatch() implementation to

return # just return immediately :-)

This is part of the implementation to record information while running
on English and then run on Localized software automatically
afterwards.

I have changed my local copy and when I get a breather from other
stuff going on I will merge it up to SubVersion (I am currently
working on a Branch).

Note after this there will be a tiny leak still - but I haven't time
to track that down at the moment. (and it may not be a full leak -
just caching data not hit before)

Thanks
   Mark
