使用 JButton 在 Java 中创建自定义按钮 [英] Creating a custom button in Java with JButton

问题描述

我正在尝试创建一个具有自定义形状(六边形)的按钮，但其他方面的行为与普通 JButton 一样(即，与 ActionListener 配合使用).

I am trying to create a button that has a custom shape (hexagon), but otherwise acts like a normal JButton would (that is, works with an ActionListener).

我创建了一个扩展 AbstractButton 的类，但是当我单击它时，它似乎没有向 ActionListener 发送事件.如果我更改类以扩展 JButton，它可以完美运行，但会破坏按钮的显示方式.我假设有一个方法需要重写才能触发事件，但我不知道它是什么.

I have created a class that extends AbstractButton, but it doesn't seem to be sending events to the ActionListener when I click it. If I change the class to extend JButton it works perfectly, but it screws up the way the button is displayed. I'm assuming that there is a method that I need to override to get it to fire events, but I can't figure out what it is.

推荐答案

您将不得不扩展 JButton 类而不是 AbstractButton.尝试以下事情，你就会有想法.

You will have to extend JButton class not AbstractButton. Try the following things and you will get idea.

第一步是继承JButton.

然后，在您的子类中，首先重新定义 paintComponent(Graphics) 方法.如果您想要任何更改.

Then, in your subclass, start by redefining the paintComponent(Graphics) method. If you want any changes.

然后，覆盖 paintBorder(Graphics) 以赋予其六边形形状.

Then, override paintBorder(Graphics) to give it a shape of hexagon.
