QTableWidget Highlight Partial Text

Punit

Hello all,

I have a search box (QLineEdit) and a QTableWidget. Now suppose if I enter the word "xyz" in search box than if any QTablewidget cell contains that specific text i.e. "xyz", I want to highlight that part of the text with yellow color. (ctrl+f behavior in QT).

Please help. I have tried many ways to do this, but not succeeded yet.

Thanks.

it's not crazy difficult, you just need to subclass QStyledItemDelegate, add a member to hold the string and reimplement the paint method to do the highlight

I am trying to do this. I am a newbiew, so need your assistance. Hope you can understand. Here are some rough code.

MediaFileItemDelegate::MediaFileItemDelegate(QObject *parent) :QStyledItemDelegate(parent)
{

}

MediaFileItemDelegate::~MediaFileItemDelegate()
{

}

void MediaFileItemDelegate::paint(QPainter* painter, const QStyleOptionViewItem& option,const QModelIndex& index) const
{
    QString str = qvariant_cast<QString>(index.data());

    painter->save();

    painter->setPen(Qt::NoPen);

   // painter->drawRect(option.rect);

    if(index.data().toString().contains("xyz"))
    {
        painter->setPen(Qt::blue);
        painter->drawText(option, str);
    }
    else
    {
        QStyledItemDelegate::paint(painter, option, index);
    }

    painter->restore();
}

Currently this code is highlighting the whole text (example: My name is xyz) and I am doing manually matching. So how can i select only xyz. Thanks
