QFileSystemModel should support QRegExp Filter

[RobotR]

Not only Wildcard, but also RegExp.
I have found it hard to hide the backup files whose name is like "~anyfile.txt","#anyfile.txt" and etc.

Have you tried using a QSortFilterProxyModel? As the name implies it is the recommended way to sort and filter other models before they are displayed in a view.

I haven't used QSortFilterProxyModel before. Let me try it.

Thank you very much!

It is very convenient to use QSortFilterProxyModel.

But new problem emerged...

QFileSystemModel::index() will generate modelIndex which haven't created yet. QSortFilterProxyModel do not know the new created modelIndex node. So when I try to use :

@QModelIndex index = _proxyModel->mapFromSource(_mode->index(strDirPath));

myView->scrollTo(index, QAbstractItemView::PositionAtCenter);@

It is crashed in "scrollTo". index is valid ,but parent of index is not valid.

I have found way to solve this problem:

reset the relationship of proxymodel and sourcemodel
