Hide the border of the selected cell in qtablewidget in pyqt?

Question

Is there a way i can hide the border of the selected cell(or make the border color as white)in a qtablewidget.. By default a border with dotted line is shown.. Can u help me...

Answer 1

It looks like this dotted border around selected cell you're trying to hide is a focus rectangle. Any given cell can have focus and not be selected at the same time and vice-versa. If you want this border to not get painted use an item delegate. There you can remove State_HasFocus style from the item's state before painting it. Pls, see an example below on how to do this, it's c++, let me know if you have troubles converting it to python

// custom item delegate class
class NoFocusDelegate : public QStyledItemDelegate
{
protected:
    void paint(QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const;
};

void NoFocusDelegate::paint(QPainter* painter, const QStyleOptionViewItem & option, const QModelIndex &index) const
{
    QStyleOptionViewItem itemOption(option);
    if (itemOption.state & QStyle::State_HasFocus)
        itemOption.state = itemOption.state ^ QStyle::State_HasFocus;
    QStyledItemDelegate::paint(painter, itemOption, index);
}
...
// set the item delegate to your table widget
ui->tableView->setItemDelegate(new NoFocusDelegate());

hope this helps, regards
