    it seems that there is no good way to filter...
    i think i have to re-setup the QTreeWidget/QListWidget everytime i select a different type of filterType...

    because i found there is not way to use QFileSystemMode or QSortFilterModel while i use QTreeWidget/QListWidget

          How many files/folders are you going to handle that way ?

              Then why don't you use a QFileSystemModel ?

                @SGaist i don't know how to use it...because i use QTreeWidget but not QTreeView...
                i think i even can't find a setModel() api in QTreeWidget/QListWidget...

                  You have to use QTreeView/QListView classes when using a model like that.

                          Refactoring might be hard but it's generally a good thing to have a clean code base
