## Detailed Description
该QTreeWidgetItem类提供的项目与使用[QTreeWidget](qtreewidget.html)方便的类。
树部件项目用于容纳的行信息树窗口小部件。行通常包含若干列的数据,每一个都可以包含一个文本标籤和一个图标。
该QTreeWidgetItem类是替换QListViewItem类的Qt 3一个方便的类。它提供了一种用于产品的使用[QTreeWidget](qtreewidget.html)类。
货品一般构造与父母,要么是一个[QTreeWidget](qtreewidget.html)(顶级项目)或QTreeWidgetItem (关于树的下级项目) 。例如,下面的代码构造一个顶级项目,代表了世界城市,并增加了对奥斯陆的一个子项一个条目:
```
QTreeWidgetItem *cities = new QTreeWidgetItem(treeWidget);
cities->setText(0, tr("Cities"));
QTreeWidgetItem *osloItem = new QTreeWidgetItem(cities);
osloItem->setText(0, tr("Oslo"));
osloItem->setText(1, tr("Yes"));
```
项目可以在一个特定的顺序添加指定他们也跟着当他们建造的项目:
```
QTreeWidgetItem *planets = new QTreeWidgetItem(treeWidget, cities);
planets->setText(0, tr("Planets"));
```
在一个项目的每一列都可以有其自己的背景刷子设置与[setBackground](qtreewidgetitem.html#setBackground)()函数。当前的背景刷可以找到[background](qtreewidgetitem.html#background)( ) 。对每一列中的文本标籤可以与它自己的字体和刷子来呈现。这些都与指定[setFont](qtreewidgetitem.html#setFont)()和[setForeground](qtreewidgetitem.html#setForeground)()函数,并读取与[font](qtreewidgetitem.html#font)()和[foreground](qtreewidgetitem.html#foreground)( ) 。
顶级项目以及在该树的下级之间的主要区别在于,一个顶级项目没有[parent](qtreewidgetitem.html#parent)( ) 。此信息可以用来告诉项目之间的差异,并且是要知道从树插入和取出物品时非常有用。一个项目的孩子们可以与被删除[takeChild](qtreewidgetitem.html#takeChild)() ,并插入一个给定的索引中的儿童用的清单[insertChild](qtreewidgetitem.html#insertChild)()函数。
默认情况下,项目的启用,可选择,可复,可一拖源和拖放操作。每个项目的标志可以通过调用改变[setFlags](qtreewidgetitem.html#setFlags)( )用适当的值(见[Qt.ItemFlags](qt.html#ItemFlag-enum)) 。辨认的项目可以选中和未选中的[setCheckState](qtreewidgetitem.html#setCheckState)()函数。相应的[checkState](qtreewidgetitem.html#checkState)( )函数表示该项目目前是否已选中。
### Subclassing
当子类QTreeWidgetItem提供自定义项目,可以为他们定义新类型,使他们能够从标准的项目区别开来。该构造函数需要此功能的子类需要调用基类的构造函数有一个新的类型值等于或大于[UserType](qtreewidgetitem.html#ItemType-enum)。

## Type Documentation
```
QTreeWidgetItem.ChildIndicatorPolicy
```
| Constant | Value | Description |
| --- | --- | --- |
| `QTreeWidgetItem.ShowIndicator` | `0` | 用于展开和折叠的控件将显示此项目,即使有没有孩子。 |
| `QTreeWidgetItem.DontShowIndicator` | `1` | 将永远不会被显示为展开和折叠的控制,即使有孩子。如果节点被强行打开,用户将无法展开或折叠的项目。 |
| `QTreeWidgetItem.DontShowIndicatorWhenChildless` | `2` | 用于展开和折叠的控件将显示,如果该项目包含了孩子。 |
这个枚举被引入或修改的Qt 4.3 。
```
QTreeWidgetItem.ItemType
```
这个枚举变量描述了用于描述树形控件项目的类型。
| Constant | Value | Description |
| --- | --- | --- |
| `QTreeWidgetItem.Type` | `0` | 默认类型为树部件项目。 |
| `QTreeWidgetItem.UserType` | `1000` | 对于自定义类型的最小值。以下用户等级和积分值被Qt保留。 |
您可以定义新的用户类型[QTreeWidgetItem](qtreewidgetitem.html)子类以确保自定义项目经过特殊处理,例如,当项目进行排序。
