Re: [SailfishDevel] Problem with SearchField hiding and clearing on text entry

Hi Tadeusz,

Although Qt docs don't mention it specifically, I suspect that
QSqlTableModel's setFilter method resets the model causing the attached
views redrawing themselves, including their headers. You clould use a
QSortFilterProxyModel which would not reset upon setting its filter,
resulting in the desired behaviour.

Regards Kris

I'd guess ListView recreates the header item on model reset (you can
verify by Component.onCompleted debug output). In such case you could
either try make model not do that, or then move the search field out of
header. Perhaps some hack like dummy item on header to reserve space and
then search field parented to it could provide similar UI.
