How to display QTableWidget selected row in a qLineEdit of the same class?

SGaist

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 ?

CEO.

yes., I want the contents of the selected row displayed in the qLineEdit there

CEO.

@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.

CEO.

@JonB thanks. I want the displayed values in their corresponding and different line edits. Can you write a code for that plz?
Just the function

Are you serious?

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

Then I would suggest you use the QDataWidgetMapper.

CEO.

@JonB this doesn't answer my request plz

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

CEO.

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.

CEO.

@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.
