我对erlang非常陌生，并且试图让我的脑袋围绕wxerlang，但是碰到了墙壁。有人可以看看这段代码，告诉我什么是错的。我认为这是非常明显的，但我无法解决。wxErlang - 这段代码有什么问题？

这可能有助于你得到实际的错误 – 2009-09-02 01:08:36
你也可以尝试将代码缩减为一个较小的例子，它表现出同样的问题除了使其他人更容易回答你，这是一个很好的调试自己的技巧;一旦你消除了一切无关，其余代码中的问题可能会变得更加明显 – 2009-09-02 01:30:42
我的问题在于handle_event/3的情况NEW_APP newAppDialog运行为一个新的进程并退出，但没有任何显示在框架中，主进程仍在运行，但将退回到命令行。 我很困惑，也许我已经跳到远处，并将采取在OTP的东西 – Damian 2009-09-02 08:21:44
