matplotlib导航栏错误'FigureCanvasTkAgg'对象在tkinter中没有属性'manager' [英] matplotlib Navigation Bar error 'FigureCanvasTkAgg' object has no attribute 'manager' in tkinter

问题描述

我正在尝试使用 tkinter 和 matplotlib 创建一个接口以与一些实验室设备配对，但现在我只是加载一些旧的测试数据.我正在尝试在NavigationToolbar2Tk导航栏中添加.

I am trying to use tkinter and matplotlib to create an interface to pair with some lab equipment, but right now I am just loading in some old test data. I am trying to add in the NavigationToolbar2Tk navigation bar.

当我运行程序时，栏会正确弹出，但每次单击其中一个按钮时，我都会收到错误消息FigureCanvasTkAgg"对象没有属性manager".有趣的是，除保存外，所有按钮仍将执行其操作，只是不断吐出错误.我曾尝试为导航框创建一个单独的框架，但没有奏效.

When I run the program the bar pops up properly but every time I click one of the buttons I get the error 'FigureCanvasTkAgg' object has no attribute 'manager'. The funny thing is that all of the buttons except for save will still perform their operations, they just continually spit out the errors. I have tried creating a seperate frame for the navigation box but that hasn't worked.

推荐答案

我已设法修复此错误.实际上，这是NavigationToolbar2Tk类中的错误.如果你想修复它，你必须自己修改他们的代码.您只需要在NavigationNavigatorbar2Tk类中更改一行代码.

I've managed to fix this error. It's actually a bug in NavigationToolbar2Tk class. If you want to fix it you have to modify their code yourself. You only need to change one line of code in the class NavigationToolbar2Tk.

1. 导航到 NavigationToolbar2Tk 类.
2. 导航到方法 def set_cursor(self, cursor).
3. 更改window = self.canvas.manager.window"到"window = self.window"

您不会再看到错误.
