本文整理了Java中com.google.gwt.user.client.ui.Widget.onAttach()方法的一些代码示例，展示了Widget.onAttach()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。Widget.onAttach()方法的具体详情如下：
包路径：com.google.gwt.user.client.ui.Widget
类名称：Widget
方法名：onAttach

Widget.onAttach介绍

[英]This method is called when a widget is attached to the browser's document. To receive notification after a Widget has been added to the document, override the #onLoad method or use #addAttachHandler.

It is strongly recommended that you override #onLoad() or #doAttachChildren() instead of this method to avoid inconsistencies between logical and physical attachment states.

Subclasses that override this method must call super.onAttach() to ensure that the Widget has been attached to its underlying Element.
[中]当小部件附加到浏览器的文档时，会调用此方法。要在小部件添加到文档后接收通知，请覆盖#onLoad方法或使用#addAttachHandler。
强烈建议您重写#onLoad（）或#doAttachChildren（）而不是此方法，以避免逻辑和物理连接状态之间的不一致。
重写此方法的子类必须调用super.onAttach()，以确保小部件已附加到其基础元素。
