我在仿Qt的delegate的一个例子， 想在一个tableview中设置8X8的颜色块delegate代码：
复制代码
  1. myDelegate::myDelegate(QObject *parent)
  2.     : QItemDelegate(parent)
  3. {
  4.      connect(this, SIGNAL(closeEditor(QWidget *, QAbstractItemDelegate::EndEditHint)), this, SLOT(closedelegate(QWidget *)));
  5. }
  8. myDelegate::~myDelegate()
  9. {
  12. }
  15. QWidget *myDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &, const QModelIndex &) const
  16. {
  17.     QTableWidget *editor = new QTableWidget(8, 8, (QWidget*)parent->parent()->parent());
  18. //    QTableWidget *editor = new QTableWidget(8, 8, parent);
  19.     editor->horizontalHeader()->setVisible(FALSE);
  20.     editor->verticalHeader()->setVisible(FALSE);
  21.     editor->setShowGrid(FALSE);
  22.     editor->horizontalHeader()->setDefaultSectionSize(21);
  23.     editor->verticalHeader()->setDefaultSectionSize(21);
  24.     editor->setEditTriggers(QAbstractItemView::NoEditTriggers);//设置QtableWidget的 edit状态
  25.     int m_pos;
  26.     long colorValue = 0x000000;
  28.     colorbox m_createcolor[64];
  29.     long number[64] =  {            0,     128,   8388736,  8421376,  16753920,  16720383,   16711680,   8388608,

  152.     return qstring;

遇到两个问题：
1>在tableview中设置了setEditTriggers为 每种类型都试过了 ，但是经常在tableview中点不出delegate。
2>当点出了delegate的时候选择颜色后，必需点击tableview的其他块才能让delegate更新model。


求解？？？

应该要重写Model中的 flags函数吧
Qt::ItemFlags flags(const QModelIndex &index) const;
