Hello,

how can I draw each item in a QTreeView - also the column 0 should not have a "selected" colored background.
The selected color is at the moment "blue", but only column 1 should be "blue" or other QColor.

Here is the code - thanks for helping

Qt Code: 
  1. class NoEditDelegate: public QStyledItemDelegate
  2. {
  3. public:
  4.     NoEditDelegate(QObject* parent=0): QStyledItemDelegate(parent)
  5.     {
  6.     }
  7.     virtual QWidget* createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
  8.     {
  9.         return 0;
  10.     }
  11.     void paint ( QPainter * painter, const QStyleOptionViewItem & option, const QModelIndex & index ) const
  12.     {
  13.         if (option.state == QStyle::State_Selected
  14.                 || option.state == QStyle::State_Active
  15.                 || option.state == QStyle::State_Enabled
  16.                 || option.state == QStyle::State_Item
  17.                 || option.state == QStyle::State_HasFocus)
  18.         {
  19.             QStyleOptionViewItem newOption(option);
  20.             newOption.palette.setBrush(QPalette::Highlight,QColor(200,100,200));
  21.             QStyledItemDelegate::paint(painter, newOption, index);
  22.             return;
  23.         }
  24.         QStyledItemDelegate::paint(painter, option, index);
  25.     }
  26. };
  27.
