Hi!
I've two question about wxListCtrl:
1. Why can't show the first data-record (row) the ListCtrl? (It seems
like the header hides the first row.)
2. When I re-sorting data with many header-clicks, why can I select
multiple rows (switch several rows to ACTIVE state)?
(the ListCtrl style is wxSIMPLE_SEL) Or how can I avoid this?
I've browsed the archives, but couldn't find any solution.
The attached file reproduce my problem. (this uses Robin's
wxColumnSorterMixin)
Any help welcome!
Thanks:
Attila Szüts
