    Default Find out when filtering is doing in QSortFilterProxyModel

    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 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.
