Qt QTableWidget's gray dotted border around a selected cell

Question

I'm wondering if anyone knows of, perhaps a flag to disable the gray dotted border that appears when you single click on a QTableWidget's cell.

Thanks.

Answer 1

C++: tableWidget->setFocusPolicy(Qt::NoFocus);

Python: tableWidget.setFocusPolicy(QtCore.Qt.NoFocus)

Be aware that you will lose the ability to process keyboard events, but mouse events will work fine.

Answer 2

It seems like you want to remove the border when the cell gets the focus.

Try editing the Stylesheet as follows.

QTableWidget {
    outline: 0;
}

This worked for me perfectly.

Answer 3

The easiest way to do it for me without affecting widget's focus policy and using qss is to create the following custom delegate and install it for table:

*.h:

class FocusControlDelegate : public QStyledItemDelegate {
    public:
        FocusControlDelegate(QObject *parent = 0);
        virtual void initStyleOption(QStyleOptionViewItem *option, const QModelIndex &index) const;        
        void setFocusBorderEnabled(bool enabled);

    protected:
        bool f_focus_border_enabled;
    };

*.cpp:

FocusControlDelegate::FocusControlDelegate(QObject *parent) : QStyledItemDelegate(parent) {
    f_focus_border_enabled = false;
}

void FocusControlDelegate::setFocusBorderEnabled(bool enabled) {
    f_focus_border_enabled = enabled;
}

void FocusControlDelegate::initStyleOption(QStyleOptionViewItem *option, const QModelIndex &index) const {
    QStyledItemDelegate::initStyleOption(option, index);
    if(!f_focus_border_enabled && option->state & QStyle::State_HasFocus)
        option->state = option->state & ~QStyle::State_HasFocus;
}

Answer 4

That gray dotted border indicates that that widget has focus.

Setting the below at the widget level should do the trick.

setFocusPolicy( Qt::NoFocus )

Answer 5

qApp->setStyleSheet ( " QTableWidget::item:focus { border: 0px }" );

Answer 6

QPushButton { outline: none; }
