hi all,
In the example below

Code:

---

from PyQt4 import QtCore, QtGui
 
class Ui_Dialog(QtGui.QDialog):
 
    def __init__(self,parent=None):
        QtGui.QDialog.__init__(self,parent)
        self.setObjectName("Dialog")
        self.resize(600, 500)
 
 
        self.model = QtGui.QDirModel()
        self.tree = QtGui.QTreeView()
        self.tree.setModel(self.model)
        print(self.model.flags(self.model.index("c:\Program Files")))
        self.model.setFilter(QtCore.QDir.Dirs|QtCore.QDir.NoDotAndDotDot)
 
 
        self.tree.setSortingEnabled(True)
 
        self.tree.setRootIndex(self.model.index("c:\Program Files"))
 
        #self.tree.hideColumn(1)
        #self.tree.hideColumn(2)
        #self.tree.hideColumn(3)
        self.tree.setWindowTitle("Dir View")
        self.tree.resize(400, 480)
        self.tree.setColumnWidth(0,200)
 
        self.tree.show()
        QtCore.QObject.connect(self.tree, QtCore.SIGNAL("clicked(QModelIndex)"), self.test)
        QtCore.QMetaObject.connectSlotsByName(self)
 
        self.setWindowTitle(QtGui.QApplication.translate("Dialog", "Dialog", None, QtGui.QApplication.UnicodeUTF8))
 
    def test(self,index):
 
 
        print(self.model.filePath(index))
 
        print(self.model.rowCount(index))
 
         #self.model.beginRemoveRows(index.parent(),index.row(),self.model.rowCount(index))
        #self.model.endRemoveRows()
 
        print("Row of the index =",index.row())
 
 
        print("Parent = ",self.model.data(index.parent()))
 
if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    ui = Ui_Dialog()
    #ui.show()
    sys.exit(app.exec_())

i want to remove the row and it's children (if it has) when i click on it.. (The folder under click and it's children have to be removed) I know i'm making mistake patricularly in this line..

Code:

---

self.model.beginRemoveRows(index.parent(),index.row(),self.model.rowCount(index))

---

Can u please help me in this regard .. Thanks..

if you want remove items from a model, need call removeRows() function.

QAbstractItemModel::beginRemoveRowsand QAbstractItemModel::endRemoveRows () are used to notify when a item has removed from the model, but not actually remove any items of the model.

this functions are used when create a custom model and call removeRows() to remove item from the model.
