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

[英]Returns true if the receiver is enabled, and false otherwise. A disabled menu is typically not selectable from the user interface and draws with an inactive or "grayed" look.
[中]如果接收器已启用，则返回true，否则返回false。禁用的菜单通常无法从用户界面中选择，并以非活动或“灰色”外观绘制。

代码示例

@Override
public boolean doGetBooleanValue(Object source) {
  return ((Menu) source).getEnabled();
}

代码示例来源：origin: org.eclipse.rap/org.eclipse.rap.rwt.q07

public static void writeEnabled( final Menu menu ) throws IOException {
 Boolean newValue = Boolean.valueOf( menu.getEnabled() );
 Boolean defValue = Boolean.TRUE;
 JSWriter writer = JSWriter.getWriterFor( menu );
 writer.set( PROP_ENABLED, JSConst.QX_FIELD_ENABLED, newValue, defValue );
}

    } else if ("reverse".equals(m)) {
      item.setVisible(!item.getEnabled());
    }
