Hello! Can you help me or give some advices?
I need to use QTreeView with QFilesSytemModel and I want to enable drug&drop operations on files and folders( e.g. move one file to another folder or something like this ).
For make it, I need to write new class which is inherited from QFileSystemModel class. And I need to reimplement some methods there, like:
Qt::ItemFlags flags(const QModelIndex &index) const;
Qt::DropActions supportedDropActions() const;
Qt::DragActions supportedDragActions() const;
But QFileSystem class doesn't allow to make inherited class, there are no virtual methods.
What can I do in this situation? Rewrite new QFileSystemModel class or what?
Added after 26 minutes:
Sorry for this question, this methods are virtual. It has a virtual key word in QAbstractItemModel class, but i looked it for in QFileSystemModel class.
