问题
I am using QTreeView with QFileSystemModel. It displays columns like Size, Type, Modification Date, which I don't need. How can I remove them from the view? I can't find any removeColumn in model or in view.
回答1:
Get the QHeaderView of your TreeView by calling header() on it, the headerview knows about the columns and can hide them via hideSection

I believe, this post is a duplicate of:
How can I remove columns from a QTreeView (using QDirModel)?
The only difference is that here we are using QFileSystemModel instead of QDirModel - which makes no difference since the columns needs to be hidden in the view.
So I believe pointing to the right solution is the best thing to do.
QTreeView::setColumnHidden(int column, bool hide)
