## Method Documentation
```
QTest.keyClick (QWidget widget, Qt.Key key, Qt.KeyboardModifiers modifier = Qt.NoModifier, int delay = -1)
```
模拟点击的_key_具有可选_modifier_上一个_widget_。如果_delay_大于0 ,则测试将等待_delay_毫秒。
示例:
```
[QTest](qtest.html).keyClick(myWidget, [Qt](qt.html).Key_Escape);
[QTest](qtest.html).keyClick(myWidget, [Qt](qt.html).Key_Escape, [Qt](qt.html).ShiftModifier, 200);

```
QTest.qSleep (int ms)
```
休眠_ms_毫秒,阻止执行的测试。 qSleep ( )不会做任何事件处理,并留下您的测试反应迟钝。网络通信可能会超时而睡。使用[qWait](qtest.html#qWait)( )做非阻塞睡觉。
_ms_必须大于0 。
**Note:**该qSleep ( )函数调用任一`nanosleep()`在UNIX或`Sleep()`上的窗口,因此时间在qSleep使用了()的精度依赖于操作系统。
例如:
```
[QTest](qtest.html).qSleep(250);
```
**See also** [qWait](qtest.html#qWait)( ) 。
```
QTest.qWait (int ms)
```
等待_ms_毫秒。在等待时,事件将被处理,你的测试将保持响应用户界面事件或网络通信。
例如:
```
int i = 0;
while (myNetworkServerNotResponding() && i++ < 50)
[QTest](qtest.html).qWait(250);
```
上面的代码将等待,直到网络服务器响应最多约12.5秒。
**See also** [QTest.qSleep](qtest.html#qSleep)( ) 。
```
bool QTest.qWaitForWindowShown (QWidget window)
```
等待,直到_window_显示在屏幕上。这主要是异步系统,如X11 ,其中一个窗口将被映射被要求出示自己在屏幕上后,屏幕一段时间非常有用。返回True。
例如:
```
[QWidget](qwidget.html) widget;
widget.show();
[QTest](qtest.html).qWaitForWindowShown(&widget);
```
此功能被引入Qt的4.6 。
