QStandardItemModel怎么去掉序号

QStandardItemModel是Qt中用于创建标准模型的数据结构,通常用于QTableView等控件中展示数据。如果你想在QStandardItemModel中去掉默认的行号显示,你可以通过设置每个item的文本标志(TextAlignment)来实现。具体步骤如下:
1. 创建QStandardItemModel时,不指定列的排序选项,这将避免自动添加序号列。
```cpp
QStandardItemModel model;
```
2. 当添加items到模型时,直接设置其text属性,跳过序号部分:
```cpp
QStandardItem *item = new QStandardItem("Your Data");
model.setItem(0, 0, item); // 0表示索引,1表示列
```
3. 如果已经有了带有序号的item,可以手动重置其text标志:
```cpp
QStandardItem *existingItem = model.item(0, 0);
existingItem->setTextAlignment(Qt::AlignLeft | Qt::NoTextOutline);
```
4. 可以自定义单元格样式进一步隐藏序号,例如设置边框和背景色:
```cpp
QStyleOptionViewItem option;
option.initFrom(model.views().first());
(option.widget) -> setStyle(QApplication::style()->createProxyStyle());
model.setItemData(0, 0, QVariant::fromValue(option));
```
