QTableWidget, different selection colors for the different cells - qt

Question

I'd like to have the different selection colors for the different cells of the QTableWidget.
To change selection color for the whole table I can use
QTableWidget* table = new QTableWidget;
table->setStyleSheet("QTableWidget::item{selection-background-color:#ff0000;}");
To set the usual background color of the single cells it's possible to write in the following way:
table->setItem(row, column, new QTableWidgetItem(""));
table->item(row, column)->setBackgroundColor(QColor(255,255,0));
But I couldn't find any info about the different selection colors for the different cells.
Please, help!

Answer 1

it was a very interesting question for me and I wrote an example))
I use the delegate to resolve this issue
class MyDelegate : public QItemDelegate
{
public:
MyDelegate( QObject *parent ) : QItemDelegate( parent ) { }
void paint( QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index ) const;
};
void MyDelegate::paint( QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index ) const
{
QItemDelegate::paint( painter, option, index );
QColor background = QColor(rand()%255, rand()%255, rand()%255);
QColor background2 = QColor(255, 255, 255);
painter->fillRect(option.rect, background);
if (option.state & QStyle::State_Selected) {
painter->fillRect(option.rect, background);
} else {
painter->fillRect(option.rect, background2);
}
}
how will it work? with each selection, it will generate a new color for selected item
delegate integration
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QTableWidget* m_pTableWidget = new QTableWidget();
m_pTableWidget->setRowCount(10);
m_pTableWidget->setColumnCount(10);
for (int i = 0; i < m_pTableWidget->rowCount(); ++i) {
m_pTableWidget->setItemDelegateForRow(i, new MyDelegate(m_pTableWidget));
}
m_pTableWidget->show();
return a.exec();
}
results
you can change the code and give a specific color for certain item .
