Java 大规模多框架实例问题

标签 java swing class instance frame

叹气好吧，伙计们...这里将会有大量的代码，但无论如何我都会这样做。
所以基本上，我有一个定制的(实际上它只是 JFrame 的高度定制版本)并且遇到了重大问题。

我有背景。 (公平地说，这很好)然后我有一个弹出的终端框架并吐出东西。该终端框架基于另一个名为 CustomFrame 的类。我还有另一个类，称为通知，它也是一个框架类，如终端，也基于自定义框架。

一开始，背景加载良好。终端加载良好。调用方法来显示通知窗口。这就是问题所在。通知窗口不会显示。

我尝试过frame.setVisible();框架.setSize();框架.setLocation();我已经尝试过一切。

如果我根本不显示终端，它似乎会将其代码吐到通知上，几乎就像始终只能打开一个 CustomFrame 实例一样。

我希望你理解我的问题...所以这是代码!

干杯，谢谢...很多。

编辑:

确实有时间修复字体。非常抱歉，现在已经完成了。

编辑:

这里是通知框架被调用但最终没有显示的地方:

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

最佳答案

enter image description here

正如 @Andrew Thompson、@trashgod 指出的那样，使用多个框架是一种不好的做法。

如果您仍然需要解决问题，请执行以下操作:

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

在您的Terminal 类中，您有

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

在你的Notification类中，你有

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

但是您得到的是 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，您将显示一个通知，并修改帧大小，然后调用CustomFrame的setVisible()方法。

这就是导致问题的原因。针对同一个静态实例调用 setUndecorated() 和 setVisible()。 您无法修改可见的框架。意思是，您只能在框架可见之前对其进行修改。在这里，您的框架已经可见(对于终端)，并且在显示通知时，您正在尝试更改大小和显示。这是错误的。

正如您所说我想要不同的 JFrame，就像在我的代码中一样，我使用 Types.java 作为枚举来选择不同类型的框架。由于使用不同的组件和大小，框架每次都完全不同，要实现这一点，您需要为每种类型的框架创建多个实例。
