这个是代码
- QVariant STLineModel::data(const QModelIndex &index, int role) const
- {
- if (!index.isValid())
- return QVariant();
- if (role == Qt::TextAlignmentRole) {
- return int(Qt::AlignRight | Qt::AlignVCenter);
- } else if (role == Qt::DisplayRole || role == Qt::EditRole) {
- cout<<index.column()<<" "<<index.row()<<" "<<role<<" \t"<<flush;
- }
- return QVariant();
- }
输出如下：

2 3 0 1.加载之后立刻读取两次，为啥[size=; font-size: 10pt,10pt]
0 0 0 1 0 0 2 0 0 3 0 0 0 1 0 1 1 0 2 1 0 3 1 0 0 2 0 1 2 0 2 2 0 3 2 0 0 3 0 1 3 0 2 3 0 3 3 0 [size=; font-size: 10pt,10pt]

2.双击进入编辑后又调用两次display的更新[size=; font-size: 10pt,10pt]
0 0 0 1 0 0 2 0 0 3 0 0 0 1 0 1 1 0 2 1 0 3 1 0 0 2 0 1 2 0 2 2 0 3 2 0 0 3 0 1 3 0 2 3 0 3 3 0 [size=; font-size: 10pt,10pt]

3.进入编辑状态后，会不断的刷新数据，而这个一般不需要吧，这段数据如果一直在编辑状态，会不断的刷下去[size=; font-size: 10pt,10pt]
1 1 0 1 1 0 1 1 0 [size=; font-size: 10pt,10pt]
1 1 0 1 1 0 1 1 0 [size=; font-size: 10pt,10pt]
1 1 0 1 1 0 [size=; font-size: 10pt,10pt]
1 1 0 1 1 0 1 1 0 [size=; font-size: 10pt,10pt]
4.最后刷新一遍[size=; font-size: 10pt,10pt]
0 0 0 1 0 0 2 0 0 3 0 0 0 1 0 1 1 0 2 1 0 3 1 0 0 2 0 1 2 0 2 2 0 3 2 0 0 3 0 1 3 0 2 3 0 3 3 0 [size=; font-size: 10pt,10pt]
2 3 0 [size=; font-size: 10pt,10pt]
[size=; font-size: 10pt,10pt]
我只想要加载的时候读取一遍数据，编辑某一单元格的时候读取当前单元格的数据，完成编辑后刷新一下当前单元格的数据，对model不是太熟悉，不知该重载哪些函数
