Hi guys..
I’ve used a QSortFilterProxyModel. Now in filtering the tableview (by setFilterRegExp), I want to be warned. But there isn’t nothing such signal in QSortFilterProxyModel that emitted in this case. How can i find out when the filtering is doing?!

You can subclass QSortFilterProxyModel and override QSortFilterProxyModel::setFilterRegExp (http://qt-project.org/doc/qt-4.8/qsortfilterproxymodel.html#filterRegExp-prop) to emit a signal when it is called.

No, it is not. You can make use of filterAcceptsRow() or filterAcceptsColumn(). Overriding setFilterRegExp doesn't make much sense because it is not a virtual method.

Yes. And detect a change in filter settings. Be aware though that this will make your proxy model much slower.
