How to delete row/rows from a qtableview in pyqt?

Question

I am using QStandardItemModel for my qtableview.

import ui_my_viewlogs
import os
from PyQt4 import QtCore, QtGui

class my_viewlogs(QtGui.QDialog, ui_my_viewlogs.Ui_viewlogs):
    def __init__(self):
        super(my_viewlogs, self).__init__()
        self.setupUi(self)
        self.model = QtGui.QStandardItemModel()
        self.tableView.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
        self.header_names = ['abc', 'def', 'ghi', 'kjl', 'mno', 'pqr']
        self.model.setHorizontalHeaderLabels(self.header_names)
        self.tableView.verticalHeader().setVisible(False)
        self.tableView.setShowGrid(False)
        self.selectionModel = self.tableView.selectionModel()
        self.tableView.customContextMenuRequested.connect(self.open_menu)
        self.tableView.setModel(self.model)
        self.tableView.setSelectionBehavior(QtGui.QAbstractItemView.SelectRows)

    def open_menu(self, position):
        menu = QtGui.QMenu()
        remove_selected_item_icon = QtGui.QIcon()
        remove_selected_item_icon.addPixmap(QtGui.QPixmap(":/images      /Images/deleteSelected.png"), QtGui.QIcon.Normal, QtGui.QIcon.On)
        remove_selected_item = menu.addAction(remove_selected_item_icon, "Remove selected item(s) ")
        if action == remove_selected_item:           
            model = self.model
            indices = self.tableView.selectionModel().selectedRows() 
            for index in sorted(indices):
                model.removeRow(index.row(), QtCore.QModelIndex()) 

here when I am trying to delete the row selected(i.e. model.removeRow() ) I am getting a error" TypeError: argument 1 of QAbstractItemModel.removeRow() has an invalid type".

I have searched a lot for the correct way of deleting a selected row/rows in qtableview of pyqt. However, I am not able to delete the selected row/rows.

Can you please share a sample code for deleting selected row/rows in qtableview of pyqt?

Answer 1

the method model.removeRow(index.row()) removes the row selected.

model = self.model
    indices = self.tableView.selectionModel().selectedRows() 
    for index in sorted(indices):
        model.removeRow(index.row()) 

in the indices variable we get the selected row, then we delete the row.

For deleting multiple rows in our selection of tableview:

index_list = []                                                          
for model_index in self.tableView.selectionModel().selectedRows():       
    index = QtCore.QPersistentModelIndex(model_index)         
    index_list.append(index)                                             

for index in index_list:                                      
     self.model.removeRow(index.row())
