多个列表框绑定到同一个函数

Question

老实说，我不觉得这应该发生，但它是。

self.marketList.bind('<<ListboxSelect>>', self.market_selected)
self.jobsList.bind('<<ListboxSelect>>', self.job_selected)

这两个函数之间确实没有任何更多的交互。当您单击marketList框中的一个项目时，应该会显示jobsList框中的作业。目前，它正在应用绑定两个两个盒子。当我单击jobsBox中的一个作业条目时，它会清除作业，并且我的故障排除显示它正在调用market_selected。我不知道为什么会发生这种情况，但它确实扰乱了我试图用它做的事情。

我如何确保我的绑定只在一个小部件上，而不会应用于多个小部件?

编辑:我被告知这段代码不足以重现错误。

这是所有相关的代码。

正如我前面所说的，self。当我点击jobsList

中的任何内容时，就会调用market_selected。编辑# 2我上传了整个脚本。

答案由acw1668给出。我只是在创建列表框的过程中添加了exportselection=0，效果很好。

很抱歉给大家造成了困惑，我以前从来没有在这里寻求过帮助。

谢谢你的帮助!
