我正在尝试解决行号在多个选项卡中无法正常工作的问题。问题是，当我创建新选项卡时，其他选项卡的行号不起作用，但当前选项卡的行号起作用。 语法突出显示也是如此。
我认为问题在于创建新选项卡时使用相同的变量，但我不知道如何解决此问题，并且我不确定这是否确实是问题所在。我还在考虑重新定义文本框，以及每次单击选项卡时与其关联的绑定(bind)。

最佳答案
是的，正如您所观察到的，问题是因为您总是在更改 linenumbers到最新选项卡的行号，因此对于旧选项卡，即使 _on_change()被调用时，它只会在新行号上调用重绘，而不会在旧行号上调用重绘。
我相信推进应用程序的正确方法是拥有另一个抽象级别，其中 Tab本身就是一个完整的对象，每个选项卡都应该是一个不同的对象，并且应该在其自身中存储行号/文本。

我创建了一个新类Tab并从以前的方法复制代码，如 createtext现在，当创建新选项卡时，我们只需要实例化 Tab 的对象即可类。

root.mainloop()
目前，open()不起作用，并且每个选项卡的底部标签都会出现重复，您应该考虑如何解决这些问题。可以移出的底部标签 Tab类(class)返回Arshi ，然后在 Tab 之间进行一些沟通类和Arshi当选项卡更改时，相应地更改底部标签。
此外，打开应该打开一个新选项卡，以便您可以轻松地进行操作。我还建议您理解完整的代码，然后在您的代码中使用它，而不是仅仅复制粘贴。
关于python - 行号和语法突出显示在不同选项卡上不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32064460/
