Inherit from QSortFilterProxyModel

Hello

I use a custom ProxyModel that inherits from QSortFilterProxyModel and overwrites the following methods of QSortFilterProxyModel.

Source code

 
1
2
3

protected:
    virtual bool lessThan ( const QModelIndex & left, const QModelIndex & right ) const;
	virtual bool filterAcceptsRow ( int source_row, const QModelIndex & source_parent ) const;

The constructor looks like

Source code

 
1
2

 MySortFilterProxyModel::MySortFilterProxyModel()
:   QSortFilterProxyModel() {}


Everything works pretty well, except that my ProxyModel resorts and calls filterAcceptsRow when the source model emits the dataChanged even if dynamicSortFilter is set to false.

A look at the QSortFilterProxyModel.cpp under
http://www.koders.com/cpp/fidB9A2451A0F6…e+mdef%3Ainsert
did not help me to solve the problem.

As far as I can see Trolltec's example implementation at
http://doc.trolltech.com/4.3/itemviews-c…oxymodel-h.html
does not use any tricks to inherit from QSortFilterProxyModel.

I use Qt 4.3, the QSortFilterProxyModel documentation can be found under
http://doc.trolltech.com/4.3/qsortfilterproxymodel.html

I'm grateful for any help,
norbnorb
