      Hi,

      Do you mean you want to build a string of the row and then put that in your QLineEdit ?

      For example in a slot connected to the currentCellChanged signal ?

      @SGaist thanks for your concern. I have fixed it. Now I wanna try to create different QLineEdits for each column and make the selected row display their corresponding values instead of in a single line edit.

      Have you tried such before please?

        @CEO
        You can do all this work yourself with your own line edits, but this is not the best/easiest/most efficient way to go. Instead Qt offers you two ways which (I think) are better:

        • You can make it so the QTableWidget is editable: the user clicks into a cell and edits it there. No separate line edits. If you like it that way.

        • You can use QDataWidgetMapper to "map" a whole series of separate, individual appropriate edit widgets to the columns in the selected row of a model. If you like it that way.

            Are you serious?

            I want the displayed values in their corresponding and different line edits.

            Then I would suggest you use the QDataWidgetMapper.

                What doesn't answer your request? That I write your code for you to save you learning how to do it?

                  is there anything wrong in writing a line of code to give someone a clue? I assist different people when lines of codes if I really know it and have done some works with it to guide them whenever I am suggesting an answer. It saves them from restlessness.

                    @JonB now I discovered you are either hoarding knowledge or might not have done any work on the question. I checked different contributions in some thread now and saw some members explicitly writing out lines of codes. One of them even helped me greatly and I just have to call him a pro. If you know, there's no need hoarding it.

                    Anyway, thanks for the time.

                      Yes, you're right. I have nothing better to do than lie to questioners about what I know and they should do, and I don't spend enough of my time writing the code demanded to save them time.

                      Here is an extract from my usage of the QDataWidgetMapper which I know nothing about from a sample project of mine. I'm sorry if my variables/widgets/model are not the same as yours. Also here I happen to be binding to QSpinBoxes, let me know if I need to change it to QLineEdits for you.

                      void SectorRegisters::initDataWidgetMapper()
                      {
                          // set up the `QDataWidgetMapper`
                          this->dwm = new QDataWidgetMapper(this);
                          // set model (this->sectorsModel is the model being used, in my case it's a `QStandardItemModel`)
                          SectorsModel *sectorsModel = this->sectorsModel;
                          dwm->setModel(sectorsModel);
                          // Vertical => widget mapped to row
                          dwm->setOrientation(Qt::Vertical);
                          // current index is always column #0
                          dwm->setCurrentIndex(0);
                      
                          // Region mappings
                          dwm->addMapping(ui->spinRegionSocialState, SectorsModel::RegionSocialState);
                          dwm->addMapping(ui->spinRegionGoodAreas, SectorsModel::RegionGoodAreas);
                          dwm->addMapping(ui->spinRegionPoorAreas, SectorsModel::RegionPoorAreas);
                          dwm->addMapping(ui->spinRegionCash, SectorsModel::RegionCash);
                      
                          // Here there are many further widget<->model-column mappings
                          // ...
                      }
                      

                      You're welcome.
