pip install PySimpleGUI

>>> import PySimpleGUI as psg
>>> psg.main()

1. 主窗口

import PySimpleGUI as psg

# 行 列
layout = [
    [psg.Text("Name "), psg.Input()],
    # key: 约定是是一个大写字符串，前后跟一个"-"字符。但是，可以任何字符串
    [psg.Text("Address "), psg.Input(key="-AD-")],
    [psg.Text(key="-OUT-"), psg.Button("tap1", key="-OK-"), psg.Button("tap2"), psg.Exit()],
]
window = psg.Window(
    "HelloWorld",
    layout,
    # no_titlebar=True,  # 无边框
    disable_close=True,  # 禁用关闭
    alpha_channel=0.8,  # 窗口的不透明度
    grab_anywhere=True,  # 窗口可移动
    keep_on_top=True,  # 窗口将保持在当前窗口之上
    resizable=True    # resize
)

while True:
    event, values = window.read()
    print(event, values)
    # -OK- {0: '', '-AD-': ''}

    # None 即 psg.WIN_CLOSED
    if event in (None, "Exit"):
        break
    # button有两种方式：
    elif event == "-OK-":   # button_text 被 key 取代
        window["-OUT-"].update("tap1")
        # 禁用button, 一样两种
        window["-OK-"].update(disabled=True)
    elif event == "tap2":   # 直接使用 button_text
        window["-OUT-"].update("tap2")
        window["-OK-"].update(disabled=False)
window.close()

1.1. 确认关闭

import PySimpleGUI as psg

layout = [
    [psg.Text('Hello')],
]
window = psg.Window("Calculator", layout, enable_close_attempted_event=True)
while True:
    event, values = window.read()
    print(event, values)

    if (
        event == psg.WINDOW_CLOSE_ATTEMPTED_EVENT
        and psg.popup_yes_no("Do you really want to exit?") == "Yes"
    ):
        break
    if event == psg.WIN_CLOSED:
        break

2.2. progressbar, debug

import PySimpleGUI as psg
import time

for i in range(100):
    cancel = psg.one_line_progress_meter(
      'Progress Meter', 
      i, 
      100,
      'Character Counter',
      grab_anywhere=True
    )
    if cancel == False:
        break
        
    psg.Print(i)

    time.sleep(0.1)
# 当从主窗口弹出时，需要手动关闭
# psg.one_line_progress_meter_cancel()

3. 元素类

INPUT

window = psg.Window("Table Demo", layout, size=(715, 200), resizable=True)
while True:
    event, values = window.read()
    print("event:", event, "values:", values)
    if event == psg.WIN_CLOSED:
        break
    if "+CLICKED+" in event:
        psg.popup("You clicked row:{} Column: {}".format(event[2][0], event[2][1]))
    if "add" in event:
        rows.append(["John", 22, 22])
        tbl1.update(values=rows)
window.close()
