我无法点击此JTextField进行编辑，为什么不呢？

Question

更新

仅在OS X上运行时才会发生这种情况.Windows上不存在此问题。我正在使用Eclipse Kepler和Oracle 1.7.0_45.jdk

---

以下代码是从OSGI声明性服务组件运行的基本GUI。问题是当GUI启动时，我无法与JTextField loginField进行交互。我可以与JButton loginButton进行互动。如果我运行与Java应用程序相同的代码，我可以交互/编辑JTextField。所以这个问题必须归功于它作为OSGi包发布。任何人都可以对这个问题有所了解吗？

Answer 1

经过几个小时的研究后，添加到运行配置参数的参数修复了我的问题：-noSplash。

我的日食设置：

Answer 2

  

loginField.requestFocusInWindow（）;

在窗口可见后尝试请求焦点。 （在具有此字段的窗口上调用setVisible（true）后调用此方法。）
