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，但是其他方式就像普通的JButton一样（也就是说，与ActionListener一起使用）。

<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它可以很好地工作，但它会搞砸按钮的显示方式。我假设有一个方法需要覆盖以使其触发事件，但我无法弄清楚它是什么。

解决方案

您必须扩展 JButton 类而不是 AbstractButton 。尝试以下事项，你就会明白。

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。如果你想要任何改变。

然后，覆盖 paintBorder（Graphics）给它一个六边形。

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).

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.

解决方案

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

The first move is to subclass JButton.

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

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