## Detailed Description
该QToolBox类提供了选项卡式窗口小部件项目的列。
工具箱是显示卡另一个上方的一列，与当前选项卡下面显示当前项目的Widget。每个标籤具有标籤的列中的索引位置。一个标籤的项目是[QWidget](qwidget.html)。
每个项目都有一个[itemText](qtoolbox.html#itemText)（） ，可选[itemIcon](qtoolbox.html#itemIcon)（） ，可选[itemToolTip](qtoolbox.html#itemToolTip)（） ，和一个[widget](qtoolbox.html#widget)（ ） 。该项目的属性可以与被改变[setItemText](qtoolbox.html#setItemText)（ ）[setItemIcon](qtoolbox.html#setItemIcon)（）和[setItemToolTip](qtoolbox.html#setItemToolTip)（ ） 。每个项目可以启用或禁用单独[setItemEnabled](qtoolbox.html#setItemEnabled)（ ） 。
项目，采用加[addItem](qtoolbox.html#addItem)（），或者使用插入在特定位置[insertItem](qtoolbox.html#insertItem)（ ） 。的总项数由下式给出[count](qtoolbox.html#count-prop)（ ） 。项目可以用delete删除，或从工具箱中删除[removeItem](qtoolbox.html#removeItem)（ ） 。结合[removeItem](qtoolbox.html#removeItem)（）和[insertItem](qtoolbox.html#insertItem)（）允许您将项目移到不同的位置。
目前项目widget的指数是由返回[currentIndex](qtoolbox.html#currentIndex-prop)（ ），并设置用[setCurrentIndex](qtoolbox.html#currentIndex-prop)（ ） 。特定项目的索引可以使用被发现[indexOf](qtoolbox.html#indexOf)（ ） ，和一个给定的索引处的项目被退回[item](index.htm#item)（ ） 。
该[currentChanged](qtoolbox.html#currentChanged)在当前项目改变（ ）信号被发射。

## Method Documentation
```
QToolBox.__init__ (self, QWidget parent = None, Qt.WindowFlags flags = 0)
```
该_parent_的说法，如果不是没有，原因_self_通过Qt的，而不是PyQt的拥有。
构造一个新的工具箱给定的_parent_和标志，_f_。
```
int QToolBox.addItem (self, QWidget item, QString text)
```
该_item_说法有它的所有权转移给Qt的。
添加_widget_在在工具箱的底部有一个新的选项卡。新标籤的文本设置为_text_和_iconSet_被显示到的左_text_。返回新的选项卡的索引。
```
int QToolBox.addItem (self, QWidget item, QIcon iconSet, QString text)
```
该_item_说法有它的所有权转移给Qt的。
这是一个重载函数。
添加小工具_w_在在工具箱的底部有一个新的选项卡。新标籤的文本设置为_text_。返回新的选项卡的索引。
```
QToolBox.changeEvent (self, QEvent)
```
从重新实现[QWidget.changeEvent](qwidget.html#changeEvent)（ ） 。
```
int QToolBox.count (self)
