问答游戏：python tkinter 等待点击按钮继续执行代码，然后退出

Question

这学期我参加了网络编程课，我的项目是一个问答游戏，有一个简单的图形界面。

我想显示问题，就像玩家点击一个按钮来回答一样。

问题是，我不知道如何在python 中编写"wait for click"，代码一直执行到最后。

我尝试在 boolean 条件下使用一段时间（如果没有点击则等待），这正在等待我想要的，但没有显示图形界面...

这是我的代码，我有点绝望

提前感谢您的帮助。

Answer 1

如果您希望程序等待按钮单击，那么您应该将下一个要执行的代码放在按钮回调命令中。我将问题询问代码移动到一个名为nextQuestion 的方法中，在满足条件后在checkAnswer 中调用该方法。我还用足够多的 cmets 进行了一些小的改进来解释它们（我认为）。

完整代码如下：
