Python 搜索引擎 GUI(PySimpleGui) - 带有 right_click_menu 的列表框

如何解决Python 搜索引擎 GUI(PySimpleGui) - 带有 right_click_menu 的列表框

我在右键菜单上有 OPEN 和 SAVE 选项，允许用户使用 PySimpleGui 在 ListBox 输出中打开或保存选定的多个文件.. 我在触发这些事件时遇到错误.. 你能帮忙吗？请参考下面我编写但有错误的代码。

import PySimpleGUI as sg
from tkinter.filedialog import asksaveasfile

import os
import threading
from time import sleep
from random import randint

def search(values,window):
    """Perform a search based on term and type"""
    os.chdir('G:\MOTOR\DataExtracts/')
    global results
    # reset the results list
    results.clear() 
    results = []
    matches = 0 # count of records matched
    records = 0 # count of records searched
    window['-RESULTS-'].update(values=results)
    window['-INFO-'].update(value='Searching for matches...')

    # search for term and save new results
    for root,_,files in os.walk(values['-PATH-']):
        for file in files:
            records +=1
            if values['-ENDSWITH-'] and file.lower().endswith(values['-TERM-'].lower()):
                results.append(f'{file}')
                window['-RESULTS-'].update(results)
            if values['-STARTSWITH-'] and file.lower().startswith(values['-TERM-'].lower()):
                results.append(f'{file}')
                window['-RESULTS-'].update(results)
            if values['-CONTAINS-'] and values['-TERM-'].lower() in file.lower():
                results.append(f'{file}')
                window['-RESULTS-'].update(results)
                
                matches += 1

解决方法

代码修改如下

    results = []
    matches = 0 # count of records matched
    records = 0 # count of records searched
    window['-RESULTS-'].update(values=results)
    window['-INFO-'].update(value='Searching for matches...')
    window.refresh()

    # search for term and save new results
    for root,_,files in os.walk(values['-PATH-']):    # path information of file missed here
        for file in files:
            records +=1
            if any([values['-ENDSWITH-']   and file.lower().endswith(values['-TERM-'].lower()),values['-STARTSWITH-'] and file.lower().startswith(values['-TERM-'].lower()),values['-CONTAINS-']   and values['-TERM-'].lower() in file.lower()]):
                results.append(f'{file}')

                matches += 1
    window['-RESULTS-'].update(results)
    window['-INFO-'].update('Enter a search term and press `Search`')
