问题描述
以下是第一遍工作。选择文件/秒，激活查看按钮和定义，查看文件。都好。 尝试选择另一个文件时，在选择过程中，GUI 会突然关闭。 我试图找出需要重置的变量，但这并没有改变。 在所有进口之后：
root = tk.Tk()
root.title("Motion GUI")
root.minsize(width=1000,height=700)
root.maxsize(width=1400,height = 900)
mainframe = ttk.Frame(root,padding="3 3 12 12")
mainframe.grid(column=0,row=0,sticky=(N,W,E,S))
root.columnconfigure(0,weight=1)
root.rowconfigure(0,weight=1)
WidgetFrame = ttk.Frame(mainframe,borderwidth=2,relief='ridge',height = 60)
WidgetFrame.grid(column=0,sticky="E,W")
def CreateWidgets():
link_Label = Label(WidgetFrame,text ="Select File(s): ",bg = "#E8D579")
link_Label.grid(row = 1,column = 0,pady = 5,padx = 5)
WidgetFrame.sourceText = Entry(WidgetFrame,width = 50,textvariable = sourceLocation)
WidgetFrame.sourceText.grid(row = 1,column = 1,padx = 5,columnspan = 2)
source_browseButton = Button(WidgetFrame,text ="browse",command = Sourcebrowse,width = 15)
source_browseButton.grid(row = 1,column = 3,padx = 5)
viewButton = Button(WidgetFrame,text ="View File(s)",command = ViewFile,width = 15)
viewButton.grid(row = 3,padx = 5)
def Sourcebrowse():
WidgetFrame.files_list = list(filedialog.askopenfilenames(initialdir ="/mnt/data/Motion_Data/Motion_Clips",title="Press shift key plus Left mouse click to select multiple files"))
def ViewFile():
# plays all selected files one by one,keeps speed selected in 1st clip unless changed..
files_list = WidgetFrame.files_list
for f in files_list:
player.playlist_append(f)
player.playlist_pos = 0
player.wait_for_playback
sourceLocation = StringVar()
destinationLocation = StringVar()
file_list = StringVar()
CreateWidgets()
root.mainloop()
我错过了什么？
解决方法
这是包含所有按钮和功能的完整代码。顺便说一句，所有其他按钮和功能都可以正常工作（即：复制/移动/删除）：
#!/usr/bin/python3
import os
import shutil
import tkinter as tk
from tkinter import *
from tkinter import filedialog,messagebox
from tkinter import ttk
import webbrowser
if os.environ.get('DISPLAY','') == "":
print('no display found.Using :0.0')
os.environ.__setitem__('DISPLAY',':0.0')
##### MPV.py HAS TO BE copied into the directory which imports mpv ######

player = mpv.MPV(ytdl=True,input_default_bindings=True,input_vo_keyboard=True,osc=True)
