问题描述
我正在尝试编写看板。但是如果一列有两个或更多的贴纸，通常只有第一次单击此列中的贴纸时，才会显示带有按钮的 JToolBar。 我以为坐标有问题，但我没有发现。 StickerListener 响应事件，如果坐标正确，甚至会打印“условие работает”，但 JToolBar 仍然不可见。

解决方法
问题出在 StickerListener.mouseClicked() 的控制流程中：您搜索贴纸以找到被点击的贴纸。
由于 if / else，您为每个未被点击的贴纸重置了工具栏，这意味着您的代码只有在您点击最后一个贴纸时才有效（按迭代顺序）。
如果您将代码从 else 部分移到循环之前（以便它只执行一次），您的代码将起作用：
