Swing UI布局分析

Question

我正在扩展具有Java Swing GUI的应用程序。我已经扩展了业务逻辑并添加了所需的功能，但现在我想改进UI。我从来没有用过swing，代码也不容易阅读。

在应用程序运行时，有什么方法可以分析/识别UI组件吗？我使用IntelliJ作为IDE。

Answer 1

如果您正在使用的IntelliJ GUI构建器

我建议考虑看看这两个网站，here和here。

他们继续如何你可以Set the components properties。这样做可以让您使用不同的前景和背景颜色，这可以让您识别何时启动应用程序。

深入更多的属性，可以发现here

您也可以为每个组件，这将让你找到他们的代码更易于设置的变量名。

如果您仍然在查找源代码中的组件时遇到问题，IntelliJ有一个很好的方法来Search The Source Code任何你想找的。

如果你做手工

应用作为了GUI builder，你可以设置背景颜色等，通过使用类似component.setBackground(Color.BLUE);有事找他们更容易在应用程序运行。您还可以通过使用textArea.setText("My Text");将某些默认元素提供给某些内容，如JTextArea。

这里有一些关于Swing Naming Conventions和Java Naming Conventions一般的很好的阅读。这将允许您将代码布置在清洁器中，更易于阅读时尚。

还有this网站可以查看每个摆动组件的外观。您可以点击每个组件以获取更多信息。

作为一个更一般的答案，我建议您查看一下Oracle Swing Tutorials以更好地了解Swing及其功能。我个人不建议使用任何形式的GUI构建器。你没有得到与手工完成相同的知识。

Answer 2

要讲更多的GUI构建器：它们也倾向于生成很多难以理解的代码。 GUI构建器可能最适合创建快速GUI或创建快速草图，但不推荐将其用于复杂的GUI，因为代码变得难以维护。 NetBeans的GUI构建器就是一个简单易用的好例子，但会生成大量不可编辑的代码。另一方面，Window Builder Pro与NetBeans的GUI构建器的代码相同，但代码较少，但实际上允许您编辑它生成的代码。

这种方法：

public static void showStructure(Container container, int depth) { 
    Component[] components = container.getComponents(); 
    StringBuilder indent = new StringBuilder(); 
    for (int ii = 0; ii < depth; ii++) { 
     indent.append("\t"); 
    } 
    for (int ii = 0; ii < components.length; ii++) { 
     System.out.print(indent); 
     Component component = components[ii]; 
     System.out.print(component.getClass().getSimpleName() + "\t"); 
     if (component instanceof Container) { 
      Container c = (Container) component; 
      System.out.println(c); 
      showStructure(c, depth+1); 
     } 
    } 
}
