第一次尝试 PySimpleGui,想要创建一个 exec 程序,允许用户将目录/文件移动或复制到他们选择的目的地,但并不真正了解如何将操作链接到按钮。

我当前的程序如下所示:

import PySimpleGUI as sg
import shutil, errno
src = ""
dest = ""
def copy(src, dest):
    try:
        shutil.copytree(src, dest)
    except OSError as e:
        # If the error was caused because the source wasn't a directory
        if e.errno == errno.ENOTDIR:
            shutil.copy(src, dest)
        else:
            print('Directory not copied. Error: %s' % e)

#Me testing out commands in PSG
layout = [[ sg.Text("Select path from source to 
destination")],
[sg.Text("Source Folder", size=(15,1)), sg.InputText(src), 
sg.FolderBrowse()],
[sg.Text("Destination Folder", size=(15,1)), 
sg.InputText(dest), sg.FolderBrowse()],
[sg.Button("Transfer", button_color=("white", "blue"), size= 
(6, 1)),sg.Button(copy, "Copy", button_color=("white", 
"green"), size=(6, 1)),sg.Exit(button_color=("white", "red"), 
size=(6, 1))]]

event = sg.Window("Mass File Transfer").Layout(layout).Read()

据我所知,我认为将复制命令包含在按钮的属性中会将其链接到代码中前面定义的命令。我将 src 和 dest 空白作为 src 和 dest 的输入,并添加了浏览文件夹扩展名,以便于文件管理。

没有按钮与函数的“链接”,也没有回调函数。

要执行您正在寻找的操作,请在从读取返回“复制按钮”事件时调用复制。

我敦促您通读文档以了解这些对 Button 等的调用是如何工作的。 http://www.PySimpleGUI.org

这就是我认为你正在寻找你的代码来做的事情:

import PySimpleGUI as sg
import shutil, errno
src = ""
dest = ""
def copy(src, dest):
    try:
        shutil.copytree(src, dest)
    except OSError as e:
        # If the error was caused because the source wasn't a directory
        if e.errno == errno.ENOTDIR:
            shutil.copy(src, dest)
        else:
            print('Directory not copied. Error: %s' % e)

#Me testing out commands in PSG
layout = [[ sg.Text("Select path from source to destination")],
[sg.Text("Source Folder", size=(15,1)), sg.InputText(src),
sg.FolderBrowse()],
[sg.Text("Destination Folder", size=(15,1)),
sg.InputText(dest), sg.FolderBrowse()],
[sg.Button("Transfer", button_color=("white", "blue"), size=
(6, 1)),sg.Button("Copy", button_color=("white",
"green"), size=(6, 1)),sg.Exit(button_color=("white", "red"),
size=(6, 1))]]

window = sg.Window("Mass File Transfer").Layout(layout)

while True:
    event, values = window.Read()
    print(event, values)
    if event in (None, 'Exit'):
        break

    if event == 'Copy':
        copy(values[0], values[1])
