    I created a QTableWidget and want to have each item/cell of the table editable. When I try to call tableWidget->itemAt(x,y)->setText, the item does not seem to be there (seg fault). I could create a widget for each cell, but it seems very tedious. Is this the way the QTableWidget supposed to be?

    Also none of the cells is editable. I tried in the designer to mark the cell item as editable, but it is not working.

    I don’t see a way to set the column width either. Any help is appreciated.

      Hi,

      Did you create all necessary QTableWidgetItems before calling itemAt ? Also be aware that itemAt use mouse coordinates, are you sure you want that ?

        Yes you are right, should use item(row, col) instead!

        I still have these 2 problems:

        • can not make each cell editable. I specifically set the item to be editable:

        @ QTableWidgetItem *wi = new QTableWidgetItem();
        wi->setFlags(Qt::ItemIsSelectable | Qt::ItemIsEditable | Qt::ItemIsEnabled);
        tableWidget->setItem(row, c, wi);@

        But it does not work

        • How can I specify the width of each column? Tried to set the width for one item, but it does not work.

          AFAIK, they are editable by default.

          "setColumnWidth":http://qt-project.org/doc/qt-5/qtableview.html#setColumnWidth is what you are looking after
