本文整理了Java中org.eclipse.swt.widgets.Menu.isVisible()方法的一些代码示例，展示了Menu.isVisible()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。Menu.isVisible()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.Menu
类名称：Menu
方法名：isVisible

[英]Returns true if the receiver is visible and all of the receiver's ancestors are visible and false otherwise.
[中]如果接收器可见且所有接收器的祖先都可见，则返回true，否则返回false。

  if (theMenu != null && !theMenu.isDisposed() && theMenu.isVisible()) {
    updateIfNecessary();
  }
}
