如何在 Java 中使用条件图标？
[英]How can I use an icon for a conditional in Java?
问题描述
I'm working on a TicTacToe game with buttons that shows icons for each move.
我正在开发一个 TicTacToe 游戏，其按钮显示每个动作的图标。 The issue is that there is no way I found to avoid a button being reused after a turn and the only way I found to avoid the reuse of the button is by setting and text and verifying if the button has that text or not (and then proceed to block the button or not).问题是我发现无法避免按钮在转弯后被重用，而我发现避免重用按钮的唯一方法是设置和文本并验证按钮是否具有该文本（然后是否继续阻止按钮）。 I would like to know if there is a way to use my icons for the conditional like for example: if the button has an x icon, then the button is blocked.我想知道是否有一种方法可以将我的图标用于条件，例如：如果按钮有一个 x 图标，则该按钮被阻止。 Something like that.类似的东西。
Here is my code:这是我的代码：

Icons can be shared by multiple components.图标可以由多个组件共享。 So there is no need to create a new ImageIcon every time you click on a button.因此，无需每次单击按钮时都创建新的 ImageIcon。
Instead create an xIcon and oIcon in the constructor of your class to use in later processing.而是在 class 的构造函数中创建一个 xIcon 和 oIcon 以在以后的处理中使用。
When you click on a button you can then just use:当您单击一个按钮时，您可以使用：
Icon icon = selected.getIcon();
if (icon == null)
// do something
