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.

yes that is the only way!

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.Originally Posted by alizadeh91

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