Tkinter窗口最大化时误触发按钮点击的问题求助

我希望仅在点击按钮时执行button_clicked()函数打印Market ID和Player ID，但双击Windows窗口边缘的蓝色区域进行垂直最大化时，会误触发标注为Roger Federer的按钮点击事件，需要找到仅在点击按钮时才执行函数的解决方法。

成因分析 #

在Windows系统中，双击窗口边缘触发最大化操作时，窗口管理器会发送鼠标事件到窗口的特定位置。当窗口大小变化导致内部组件重新布局后，Roger Federer按钮的位置恰好与该鼠标事件的位置重合，从而被误判为按钮点击事件。此外，Tkinter的组件重排逻辑在窗口尺寸变更时，可能会让组件意外捕获到非用户主动触发的鼠标事件。

解决方案 #

通过将按钮的命令绑定从command参数改为直接绑定<Button-1>事件（即鼠标左键点击事件），确保只有用户主动点击按钮时才触发button_clicked()函数，避免窗口调整时的误触发。
