PySide: QFileSystemModel - Display/Show Root Item
0
i am using QFileSystemModel to display subdirectories of a set root path in a QTreeView. Works all fine but it would be very nice to also see the Root item as it is hidden right now.
model = QtGui.QFileSystemModel()
model.setRootPath(path)
treeview.setModel(model)
treeview.setRootIndex(model.index(path))
treeview.show()
EDIT: OS is Windows 7
python pyside qtreeview qfilesystemmodel

The idea is to use as root the parent directory and filter the sibling directories, for this I created a QSortFilterProxyModel that receives an index from the desired directory but you must pass it a QPersistentModelIndex since the latter is permanent unlike the QModelIndex that can be changed in any moment.
import os
from PySide import QtCore, QtGui
class FileProxyModel(QtGui.QSortFilterProxyModel):
def setIndexPath(self, index):
self._index_path = index
self.invalidateFilter()
def filterAcceptsRow(self, sourceRow, sourceParent):
if hasattr(self, "_index_path"):
ix = self.sourceModel().index(sourceRow, 0, sourceParent)
if self._index_path.parent() == sourceParent and self._index_path != ix:
return False
return super(FileProxyModel, self).filterAcceptsRow(sourceRow, sourceParent)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
path = # ...
parent_dir = os.path.abspath(os.path.join(path, os.pardir))
treeview = QtGui.QTreeView()
model = QtGui.QFileSystemModel(treeview)
model.setRootPath(QtCore.QDir.rootPath())
proxy = FileProxyModel(treeview)
proxy.setSourceModel(model)
proxy.setIndexPath(QtCore.QPersistentModelIndex(model.index(path)))
treeview.setModel(proxy)
treeview.setRootIndex(proxy.mapFromSource(model.index(parent_dir)))
treeview.expandAll()
treeview.show()
sys.exit(app.exec_())
