    Hello, I have a QTableWidget that contains some card info.

    I want to display a card preview to the left. I used "on_CardList_pressed" function and it worked well when I click on any row.

    However, when I switch rows using arrow keys, the preview is not updating. I tried all other slots and none of them are working.

    Is there a way to know when a user highlights a different row using arrow keys?

      Hi
      What about
      void QTableWidget::cellChanged(int row, int column)

      it should also trigger with keys ?

        Well, I tried this. It only display previews while the table is initializing. So I got a million debug errors.

        The most important thing is that after the table finishes initialization, it's not triggering anymore. Whether I click or use arrow keys the function is never called again.

        EDIT: Nevermind. I used on_CardList_currentCellChanged and everything worked just fine. Thanks for the suggestion.
