在矩形类缩放中选择区域时出错(wx.frame) [英] error when select area inside rectangle class zoom(wx.frame)
本文介绍了在矩形类缩放中选择区域时出错(wx.frame)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在对矩形选择器内的绘图区域有一些帮助后，我工作了，但是当我在某些代码应用程序中应用时，我遇到了如下错误:
after have some help about plot area inside rectangle selector i worked but when i applicated in some code app i have error like :
Traceback (most recent call last):
File "C:\Users\majdoulina\Anaconda3\lib\site-packages\matplotlib\cbook\__init__.py", line 215, in process
func(*args, **kwargs)
File "C:\Users\majdoulina\Anaconda3\lib\site-packages\matplotlib\widgets.py", line 1597, in release
self._release(event)
File "C:\Users\majdoulina\Anaconda3\lib\site-packages\matplotlib\widgets.py", line 2194, in _release
self.onselect(self.eventpress, self.eventrelease)
TypeError: line_select_callback() missing 1 required positional argument: 'erelease'
我不知道为什么它不能在我的应用程序中运行类(缩放)一切都很好，但我不知道代码中的问题在哪里.
i don't know why it can't working the class(zoom) in my app all is good i thing but i dont know where is the problem inside code .
当我需要在矩形内选择区域时，这是第二个应用程序的代码:
this is code for second application when i need to do the select area inside rectangle :

推荐答案
要重新安排代码中的内容，以使用 panel 而不是新的 frame .虽然，只有在程序用户需要时才创建一个新框架，而现有的 panel 必须存在，无论是否需要！
It's a matter of rearranging things within the code to use a panel rather than a new frame. Although, a new frame is only created as needed by the user of the program, whilst an existing panel has to be there, whether it is needed or not!
我已经重新排列了先前的答案，以在另一个面板中显示 zoom ，但是出于我的一生，我不明白为什么您不利用内置的使用工具栏. NavigationToolbar2Wx 的matplotlib
I've rearranged a previous answer to show the zoom in another panel but for the life of me, I don't understand why you don't take advantage of the built in matplotlib toolbar using NavigationToolbar2Wx.
