本文整理了Java中com.vaadin.ui.Window.center()方法的一些代码示例，展示了Window.center()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Window.center()方法的具体详情如下：
包路径：com.vaadin.ui.Window
类名称：Window
方法名：center

Window.center介绍

[英]Sets this window to be centered relative to its parent window. Affects windows only. If the window is resized as a result of the size of its content changing, it will keep itself centered as long as its position is not explicitly changed programmatically or by the user.

NOTE: This method has several issues as currently implemented. Please refer to http://dev.vaadin.com/ticket/8971 for details.
[中]将此窗口设置为相对于其父窗口居中。仅影响windows。如果窗口的大小因其内容的大小而改变，则只要其位置没有以编程方式或用户明确更改，它就会保持居中。
注意：该方法在当前实施时存在几个问题。请参阅http://dev.vaadin.com/ticket/8971详细信息。
