如何在Swing中组织我的动作？ [英] How do I organize my Actions in Swing?

问题描述

我正在替换我的匿名ActionListeners

I am currently replacing my anonymous ActionListeners

new ActionListener() {
    @Override
    public void actionPerformed(final ActionEvent event) {
        // ...
    }
}

包含表示操作的类文件：

with class files representing actions:

public class xxxxxxxAction extends AbstractAction {
}

但是，我的GUI能够执行很多操作（例如CreatePersonAction，RenamePersonAction，DeletePersonAction，SwapPeopleAction等） 。）。

However, my GUI is able to perform a lot of actions (eg. CreatePersonAction, RenamePersonAction, DeletePersonAction, SwapPeopleAction, etc.).

有没有一种方法可以将这些类组织成一个连贯的结构？

Is there a good way to organize these classes into some coherent structure?

推荐答案

您可以将您的操作保存在单独的包中以隔离它们。有时，将它们保存在一个类中是有用的，特别是如果操作是相关的或具有共同的父级，例如：

You can keep your actions in a separate package to isolate them. Sometimes, it is useful to keep them in one class, especially if actions are related or have a common parent, for example:

public class SomeActions {
    static class SomeActionX extends AbstractAction {
        @Override
        public void actionPerformed(ActionEvent e) {
        }
    }

    static class SomeActionY extends AbstractAction {
        @Override
        public void actionPerformed(ActionEvent e) {
        }
    }

    static class SomeActionZ extends AbstractAction {
        @Override
        public void actionPerformed(ActionEvent e) {
        }
    }
}

然后访问它们：

JButton button = new JButton();
button.setAction(new SomeActions.SomeActionX());
