python - PyQt: QFileSystemModel checkbox filter -


i trying make utility using python/pyqt create *.tar archive qfilesystemmodel (including items checked). want control of qfilesystemmodel checkboxes filter filename / filetype / filesize.

how can check/uncheck qfilesystemmodel checkboxes outside of class wildcard search on filename / filetype / filesize?

class checkabledirmodel(qtgui.qfilesystemmodel):     def __init__(self, parent=none):         qtgui.qfilesystemmodel.__init__(self, none)         self.checks = {}      def data(self, index, role=qtcore.qt.displayrole):         if role != qtcore.qt.checkstaterole:             return qtgui.qfilesystemmodel.data(self, index, role)         else:             if index.column() == 0:                 return self.checkstate(index)      def flags(self, index):         return qtgui.qfilesystemmodel.flags(self, index) | qtcore.qt.itemisusercheckable      def checkstate(self, index):         if index in self.checks:             return self.checks[index]         else:             return qtcore.qt.checked      def setdata(self, index, value, role):         if (role == qtcore.qt.checkstaterole , index.column() == 0):             self.checks[index] = value             self.emit(qtcore.signal("datachanged(qmodelindex,qmodelindex)"), index, index)             return true          return qtgui.qfilesystemmodel.setdata(self, index, value, role)        self.dirtreeview = qtgui.qtreeview(self.centralwidget)     self.dirmodel = checkabledirmodel()     self.dirtreeview.setmodel(self.dirmodel)
