Question

我认为我的actionListeners有些混乱。我应该有两个按钮块。

第一个面板是16个按钮x 16个按钮（总共256个按钮）。第二个面板是8个按钮x 2个按钮（总共16个按钮）我能够将“ColorChooser”中的“蓝色”传递到两个面板。

但是，第二个面板应该变为RED。不是蓝色。我的第二个问题 - 第2小组看起来正确。它从1开始，然后转到16.但是，Panel 1从17开始，到256.请，谢谢你的帮助。

我还想知道为什么按钮阵列的工具提示不起作用？

再次感谢！

我解决这个问题的方法是使用一个可以监听整个帧的ActionListener。

多个ActionListener创建问题
