        @Qt-Enthusiast There is no need to implement anything for switching focus via TAB/Shift-TAB - this should work without any code. In QtCreator/Designer you can specify the order in which Tab should got through the widgets.

              @Qt-Enthusiast I don't know why.
              But as I wrote before there is NO need to implement Shift-Tab as it should work out of the box.

                  Can you please explain why you think you have to?
                  If you want to change the order in which Tab/Shift-Tab navigates through widgets you can do it in Designer, or using https://doc.qt.io/qt-5/qwidget.html#setTabOrder in code.

                      @Qt-Enthusiast So, the ones you want to skip should never get focus? If so just use https://doc.qt.io/qt-5/qwidget.html#focusPolicy-prop
                      You can unset Qt::TabFocus, so it will not get focus via Tab.
                      Or Qt::NoFocus if it should never get focus.

                          @Qt-Enthusiast What is cellWidget here? You change the same cellWidget in the loop - I don't know how is this supposed to work? You should iterate over the cells and change their focus policy instead. Now you show that you're using a table. That is something you should have said straight from the beginning.

                              Yes - but we're a Qt forum, no python for beginners forum. Sorry.

                                So I have QtableWidget

                                as show in pictuure

                                For Row 0
                                1 ) The first column of each row is QLablel
                                2 second colum is Qlinedit

                                For Row 1 to Row2
                                1 ) The first column of each row is QLablel
                                2 second colum is QLabel

                                For Row 3 to end

                                1 ) The first column of each row is QLablel
                                2 second column has QWidget that has QSplitter(Vertical)
                                First widget of spiltter has QLineEdit
                                Other widget of splitter has QLabe;

                                My project is

                                When the user press KeyTab , the cursor should move from one QLineEdit to other Qlinedit ( it should not jump within the QLineEdit

                                Please suggest some generic way

                                For 3rd to last row the second column is Q![alt text](![image url](Table.PNG image url))
