I have ran into some trouble.我遇到了一些麻烦。 I'm quite new to OOP and working with
tkinter
and GUI's in general.我对 OOP 很
tkinter
并且一般使用tkinter
和 GUI。
I have managed to find some code on the Internet and meshed it all together to create something and I'm nearly where I want to be.我设法在 Internet 上找到了一些代码并将它们组合在一起以创建一些东西,我几乎达到了我想要的位置。
So what I want is some help figuring this out.所以我想要的是一些帮助解决这个问题。
How can I assign results of askdirectory
to a variable I can use elsewhere?如何将
askdirectory
结果分配给我可以在其他地方使用的变量?
# coding=utf-8
import tkinter as tk
from tkinter import font as tkfont
from tkinter import filedialog
class MainApp(tk.Tk):
....
class SelectFunction(tk.Frame):
....
class FunctionChangeName(tk.Frame):
....
a = Gui(self)
# this gets me the askdirectory but how to add it to a variable?
Above is the call to run askdirectory
code, and it works, just need to find out how to save it to a variable so I can use it, I have tried to print it in several ways, but all I get is something along the lines .!frame.!functionchangename.!gui
.以上是运行
askdirectory
代码的调用,它可以工作,只需要找出如何将其保存到变量中以便我可以使用它,我尝试以多种方式打印它,但我得到的只是一些东西.!frame.!functionchangename.!gui
.
class SelectDir:
def __init__(self, container, title, initial):
self.master = container
self.initial = initial
self.selected = initial
self.options = {'parent': container,'title': title,'initialdir':initial,}
def show(self):
result = filedialog.askdirectory()
if result:
self.selected = result
def get(self):
return self.selected
class Gui(tk.Frame):
def __init__(self, container):
tk.Frame.__init__(self, container)
frame = tk.Frame(container)
frame.pack()
self.seldir = SelectDir(self, "Select directory", "D:\\MyPgm\\Python\\Tiles_8")
button = tk.Button(frame, text="Select directory", command=self.select_dir)
button.grid(column=0, row=0)
self.act_dir = tk.StringVar()
self.act_dir.set("D:\\MyPgm\\Python\\Tiles_8")
entry = tk.Entry(frame, textvariable=self.act_dir, width=30)
entry.grid(column=0, row=1)
def select_dir(self):
self.seldir.show()
self.act_dir.set(self.seldir.get())
# or
# result = seldir.show()
# self.act_dir.set(result)
if __name__ == "__main__":
app = MainApp()
app.mainloop()
example, if you have f inside a function, you can make it global to have access as variable例如,如果函数中有 f,则可以将其设为全局变量以访问变量
def print_path():
# select working directory
global f #make f global to access the path
f = filedialog.askdirectory(parent=root, initialdir="/", title='Select Dir')
