## Detailed Description
该QWorkspace小部件提供一个工作区窗口，可以在MDI应用程序中使用。
此类已被否决。使用[QMdiArea](qmdiarea.html)代替。
多文档界面（MDI ）应用程序通常由包含一个菜单栏，工具栏，和中央QWorkspace部件一个主窗口。工作空间本身是用来显示多个子窗口，其中每一个是一个部件。
工作区本身就是一个普通的Qt的部件。它有一个标准的构造函数接受一个父部件。工作空间可以被放置在任何布局，但通常被给定为在中央部件[QMainWindow](qmainwindow.html)：
```
MainWindow.MainWindow()
{
workspace = new QWorkspace;
setCentralWidget(workspace);
...
}
```
子窗口（ MDI窗口）是插入到工作区中使用标准的Qt部件[addWindow](qworkspace.html#addWindow)（ ） 。与顶层窗口部件，你可以调用函数，如[show](qwidget.html#show)（ ）[hide](qwidget.html#hide)（ ）[showMaximized](qwidget.html#showMaximized)（）和[setWindowTitle](qwidget.html#windowTitle-prop)（ ）在子窗口更改工作区中它的外观。您也可以提供窗口部件标记，以确定装修或部件本身的行为的布局。
要更改或检索一个子窗口的几何形状，你必须在它的操作[parentWidget](qwidget.html#parentWidget)（ ） 。该[parentWidget](qwidget.html#parentWidget)（ ）提供了访问的装饰框，其中包含子窗口小部件。当一个子窗口最大化，它的装饰框被隐藏。如果顶层窗口部件包含一个菜单栏，它会显示最大化窗口的操作菜单中的菜单项的左侧，和窗口的控制，以正确的。
当它获取键盘焦点时，或者当子窗口被激活[setFocus](qwidget.html#setFocus)（）被调用。用户可以通过点击窗口或按Tab键移动焦点在通常的方法，例如激活的窗口。工作区中发射的信号[windowActivated](qworkspace.html#windowActivated)（ ）当活动窗口的变化，并且功能[activeWindow](qworkspace.html#activeWindow)（ ）返回一个指向活动的子窗口，或者0，如果没有窗口被激活。
便利的功能[windowList](qworkspace.html#windowList)（ ）返回所有子窗口的列表。此信息可以在含有窗口的列表的弹出式菜单中使用，例如。此功能也可作为部分[Window Menu](http://doc.qt.digia.com/qq/qq09-qt-solutions.html)解决方案。
QWorkspace为子窗口有两个内置的布局策略：[cascade](qworkspace.html#cascade)（）和[tile](qworkspace.html#tile)（ ） 。两者都是插槽让您可以轻松的菜单项连接到它们。
|  |  |
如果你希望你的用户能够与子窗口比可见工作区面积较大的工作，设置[scrollBarsEnabled](qworkspace.html#scrollBarsEnabled-prop)属性设置为True 。

## Type Documentation
```
QWorkspace.WindowOrder
```
指定在其中的子窗口从返回的顺序[windowList](qworkspace.html#windowList)（ ） 。
| Constant | Value | Description |
| --- | --- | --- |
| `QWorkspace.CreationOrder` | `0` | 该窗口在其创建的顺序返回 |
| `QWorkspace.StackingOrder` | `1` | 该窗口在它们的层叠顺序返回 |

## Method Documentation
```
QWorkspace.__init__ (self, QWidget parent = None)
```
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。
构造一个工作区与给定_parent_。
```
QWorkspace.activateNextWindow (self)
```
这种方法也是一个Qt槽与C + +的签名`void activateNextWindow()`。
给出了输入焦点的子窗口列表中的下一个窗口。

该_w_说法有它的所有权转移给Qt的。
添加小工具_w_作为新的子窗口的工作空间。如果_flags_是非零的，它们将复盖在部件上设置的标志。
返回用于窗口框架的窗口部件。
