Python:OpenFile 由于无法访问文本变量，对话框没有出现
Python:OpenFile dialog did not appear because of cannot access the text variable
我已经为文件对话框创建了一个按钮、一个条目和一个函数。在我按下 'browse' 按钮后，文件对话框没有出现，所以我怎样才能确保我的 custName.set(filename) 可以在我的 TracingMethod () 函数中使用。
我创建文件对话框的步骤：
第 1 步：从 tkinter 导入文件对话框
from tkinter import filedialog
第 2 步：创建按钮和条目
self.browseButton = Button(self.radioframe, text="Browse",command = self.open)
self.browseButton.grid(row =3, column =3, sticky = W)
#Define the entry
custName = StringVar(None)
location_ent =Entry(self.radioframe,textvariable = custName)
location_ent.grid(row =2, column = 2, sticky = W,columnspan=1)
location_ent.update()
location_ent.focus_set()
第 3 步：创建 open() 函数[IDE 此处显示错误]
def open():
filename = filedialog.askopenfilename(parent=root,title='Choose a file')
custName.set(filename)
我在想我是在独家新闻之外定义函数吗？
所以我提供了完整的代码以供参考。

你这里有几个错误：
custName（当然还有 location_ent）应该是 classopen 函数必须是您的 TracingInterface class 的方法并且 return 字符串必须分配给 self.custName :
class TracingInterface(Frame):
# ...
def TracingMethod(self):
# ...
self.custName = StringVar(None)
self.location_ent =Entry(self.radioframe,textvariable = self.custName)
self.location_ent.grid(row =2, column = 2, sticky = W,columnspan=2)
self.location_ent.update()
self.location_ent.focus_set()
def open(self):
filename = filedialog.askopenfilename(parent=root,title='Choose a file')
self.custName.set(filename)
顺便说一句，为了看到这个按钮，我不得不将 location_ent 的列跨度从 1 更改为 2，并将主要部分及其左侧部分的宽度增加到 100：
# Increase global width
master.minsize(width=800, height=520)
master.maxsize(width=800, height=520)
# ...
# Increase TracingMethod width
self.radioframe = LabelFrame(self,text="Tracing Method",height= 120,width =400)
# ...
# Increase columnspan
location_ent.grid(row =2, column = 2, sticky = W,columnspan=2)
# ...
# Increase otherFunction width
self.otherFrame = LabelFrame(self,text="Other Function",height= 400,width =400)
self.browseButton 小部件没有出现，因为您将 location_ent 的 columnspan 选项设置为 1。您必须将其修改为 2，因为那里也有 self. configUAButton 按钮.
这意味着您需要更改：
location_ent.grid(row =2, column = 2, sticky = W,columnspan=1)
收件人：
location_ent.grid(row =2, column = 2, sticky = W,columnspan=2)
但是你现在几乎不能 self.browseButto 因为你为 self.radioframe 设置的宽度不够。所以改变这一行：
self.radioframe = LabelFrame(self,text="Tracing Method",height= 120,width =300)
至：
self.radioframe = LabelFrame(self,text="Tracing Method",height= 120,width =355)
当然，您需要相应地修改masterwindow的width选项。为此，更改：
master.minsize(width=700, height=520)
master.maxsize(width=700, height=520)
最后，您无法到达 custName，因为您需要将其设为 instance variable。这意味着您需要更改：
self.custName = StringVar(None)
location_ent =Entry(self.radioframe,textvariable = self.custName)
收件人：
self.custName = StringVar(None)
location_ent =Entry(self.radioframe,textvariable = self.custName)
收件人：
master.minsize(width=755, height=520)
master.maxsize(width=755, height=520)
并且（因此）在 open() 方法中：
custName.set(filename)
收件人：
self.custName.set(filename)
