Java GUI变得不整洁
这是我第一次来这里。Java GUI变得不整洁,java,swing,user-interface,Java,Swing,User Interface,这是我第一次来这里。 我正在编写一个GUI驱动的程序，它允许我对.txt文件执行Caesar的密码。 然而，在我可以添加ActionListeners和ChangeListeners之前，我决定测试GUI。以下是我得到的： 代码如下： package implementation; import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class

SpringLayout允许您定义元素相对于其他元素的大小，因此，例如，您可以确保按钮看起来相同。我喜欢SpringLayout，它非常灵活，没有太多不能做到的事情。特别是，您将不再需要关心setPreferredSize。只要搜索一下，就有足够的资源了
SpringLayout允许您定义元素相对于其他元素的大小-例如，您可以确保按钮看起来相同。在这种情况下，我喜欢将我的应用程序划分为责任区。这使代码保持干净和独立，允许我在需要时替换其中的部分，而不会对应用程序的其余部分产生不利影响 这还意味着您可以关注每个部分的各个需求 对于复杂布局，最好（IMHO）使用具有单独布局管理器的复合容器，这样可以降低复杂性和奇怪交叉行为的可能性

我没有互连任何功能，但这是一个简单的例子，可以根据需要提供适当的setter和getter，以及适当的事件侦听器。在类似的情况下，我喜欢将我的应用程序划分为责任区域。这使代码保持干净和独立，允许我在需要时替换其中的部分，而不会对应用程序的其余部分产生不利影响 这还意味着您可以关注每个部分的各个需求 对于复杂布局，最好（IMHO）使用具有单独布局管理器的复合容器，这样可以降低复杂性和奇怪交叉行为的可能性
