Question

叹气好人......这里会有一些辛苦的代码，但无论如何我都会这样做。
基本上，我有一个定制的（实际上它只是JFrame的一个HEAVILY定制版本），并且遇到了重大问题。

我有一个背景。（很好，那没关系）那么我有一个终端框架弹出并吐出东西。此终端框架基于另一个名为CustomFrame的类。我还有另一个名为Notification的类，它也是一个基于自定义帧的终端ALSO的帧类。

一开始，后台加载很好。终端负载很好。调用方法以显示通知窗口。这就是问题出现的地方。通知窗口不会显示。

我试过了frame.setVisible（）; frame.setSize（）; frame.setLocation（）;我试过了，一切。

如果我根本没有显示终端，它似乎会把它的代码吐到Notification上，几乎就像只有一个CustomFrame实例在所有时间都打开。

我希望你理解我的问题......所以这是代码！

修改

是否有时间修复字体。非常抱歉，现在已经完成了。

修改

这是调用通知框架的地方，但最终没有显示：

if(!(text.length() == 13)) {
    dumpToLog();
    slowPrint("Registry not available at this current given time.\n");
    //TODO: Create registry system.
    new Notification("test");
}

Answer 1

enter image description here

正如@Andrew Thompson所说，@ trashgod指出，使用多个帧是不好的做法。

如果你仍然需要解决问题，请点击：

问题在于您的游戏应用程序的static CustomFrame实例，然后使用setUndecorated(...)等方法修改该框架实例。

在Terminal课程中，您有

static CustomFrame frame = new CustomFrame(Types.TERMINAL);

在您的Notification课程中，您有

static CustomFrame frame = new CustomFrame(Types.NOTIFICATION);

但您获得了frame

的相同实例

static JFrame frame = new JFrame(); (in your CustomFrame class)

这意味着什么：

加载游戏应用程序时，终端可见。当您注册用户时，您正在使用修改后的框架尺寸显示Notification，然后调用setVisible()的{{1}}方法。

导致问题的原因。为同一个静态实例调用CustomFrame和setUndecorated()。 您无法修改可见的框架。意思是，您只能在可见之前修改框架。在这里，setVisible()已经可见（对于终端），当显示frame时，您正试图更改大小和显示。哪个错了。

正如你所说我想要不同的JFrame，就像在我的代码中一样，我使用Types.java作为枚举来选择我不同类型的帧。由于使用了不同的组件和大小调整，每次帧都完全不同，为实现这一点，每种类型的帧需要多个实例。

更改/修复代码：
