AW: wxListCtrl thread problem

Hi,

if I take out the part that fills the SorterMixin struct, the error
doesn't come up.
Is there a known issue when the mixin struct is reused serveral times or
do I do something basically wrong ?

        # fill sorter struct

···

#
        self.listctrl_sorter[self.listctrl_cnt] = [' ' +
                                                  msg.state,
                                                  msg.date,
                                                  msg.evlpfields['mail
from'],
                                                  msg.evlpfields['rcpt
to'],

msg.headfields['subject'],
                                                  msg.file]
        self.listctrl_cnt += 1

All the best,
Harald

Ah, this may shed some light on the the subject... Are you calling wxColumnSorterMixin.__init__ more than once? Do you empty the listctrl_sorter when you empty the listctrl and fill it again?

Yes, it was initialized more than once, because I thougt I could force a
kind of garbage collection, but:

- Even when I use __init__ only once and
- I leave addlist() outside the worker thread,

I get that crash when I fill up the sorter struct the 5th time.
When I take out the sorter, everything runs stable, even with
multitrheading.
Are there any issues with reusing the sorter or any means to clean up
the sorter struct and/or the bindung between sorter and listctrl? I
tried to delete and recreate the itemDataMap dictionary but without
effect ...

I'll reduce the app and create an example these days. Thanks for your
time!

All the best,
Harald
