[Qt-interest] QStyledItemDelegate

[Lars Amsel]

Hi,

I try to customized the item delegate of a table. I want to change the background color of a cell depending on its content. The following works perfect

class MyDelegate : public QStyledItemDelegate {
protected:
  virtual void initStyleOption(QStyleOptionViewItem* option, const QModelIndex& index ) const;
};

void MyDelegate::initStyleOption(QStyleOptionViewItem* option, const QModelIndex& index ) const {
  QStyledItemDelegate::initStyleOption(option, index);
  option->palette.setColor(QPalette::Text, Qt::red);
}

Now, every cell displays its text as red. When I change the setColor to

option->palette.setColor(QPalette::Window, Qt::red);
or
option->palette.setColor(QPalette::Background, Qt::red);

Nothing happens. I guess the painter thinks the cell is transparent. But how to change that behavior?

Thanks

Lars
