[Qt-interest] QTableView is not updated after sort (Qt 4.6 Windows)

[Smokey McPott]

 The documentation for QSortFilterProxyModel states that sorting can either
be done via a proxy model or by implementing a sort function inside the
source model. I did the latter so it should work. The problem is not that
the sorting is not performed. It's just that the screen is not updated.

 Sorting is usually done using a intermediary QSortFilterProxyModel. Does
that work in your case?

Hey people,

I've written a widget that contains a QTableView which has sorting enabled.
Now, when I click the header, the sort function of the model is called but
the view is not updated. When the view gets repainted, e.g. because I
minimize the application and bring it up again, the data are shown in the
desired (updated) way. I've observed the same behaviour in Qt 4.5 but I
couldn'd  find any posts on the subject. In the source code for QTableView
most functions that change the contents of the view call
d->viewport->upate() or d->viewport->upate(rect). But the sortByColumn(int
column) function lacks a similar call. Bug or feature?

Regards
Sebastian
