QTableWidget, any easy way to make only some items tab stoppable

jronald

Have used QTableWidgetItem::setFlags to disable ItemIsSelectable and ItemIsEditable, but the item is still tab stoppable, any easy way to make a table item tab unstoppable?

Hi
What is stoppable and unstoppable ?
Never seen these words in relation to QTableWidgetItem :)

@mrjj For example

a 2x2 table
focus on cell (0,1)
press Tab key, focus to cell(1.1) instead of cell(1,0)
Is there any built in support for this?

HI
I think
http://doc.qt.io/qt-5/qabstractitemview.html#moveCursor
can be used but I have not tested it.

@mrjj
Helpful
QAbstractItemView::setCurrentIndex can be used to move to any cell
Though not so built in, but also very good way

Try reimplementing moveCursor


#include <QTableWidget>
#include <QAbstractItemModel>
class MyTableWidget : public QTableWidget{
    Q_OBJECT
    Q_DISABLE_COPY(MyTableWidget)
public:
    explicit MyTableWidget(QWidget* parent = Q_NULLPTR)
        :QTableWidget(parent)
    {}
protected:
    QModelIndex moveCursor(CursorAction cursorAction, Qt::KeyboardModifiers modifiers) Q_DECL_OVERRIDE{
        QModelIndex beginIdx = currentIndex();
        QModelIndex currIdx, prevIdx;
        if(model()){
            for(;;){
                currIdx = QTableWidget::moveCursor(cursorAction,modifiers);
                if(!beginIdx.isValid())
                    beginIdx=currIdx;
                if(!currIdx.isValid())
                    break;
                if(model()->flags(currIdx) & Qt::ItemIsSelectable)
                    break;
                if(currIdx==beginIdx)
                    break;
                if(prevIdx==currIdx)
                    break;
                prevIdx=currIdx;
                setCurrentIndex(currIdx);
            }
        }
        return currIdx;
    }

};
