PySimpleGUI：让spin支持循环

需求

自己用PySimpleGUI写了个小工具，但是发现它的spin不支持循环。
Tkinter本身的Spinbox有wrap这个开关可以觉得是否支持循环，但是没看到PySimpleGUI也支持这个特性。

代码实现

所谓spin的循环，是指当值变换到最大最小值时，可以在最大最小值直接切换。
下面我是为spin增加循环实现的代码：

import PySimpleGUI as psg
from datetime import datetime
import os
import shutil#选择窗口主题
psg.theme("Dark2")# 放大方向
zoom_directions = ["变大",  "变小"]
zoom_dir = psg.Spin(zoom_directions, readonly=True, size=5,enable_events=True, key='-ZOOM DIR-')
# 放大倍数
zoom_times = ["0.7X",  "1X", "2.5X"]
zoom_time = psg.Spin(zoom_times, readonly=True, size=5,enable_events=True, key='-ZOOM TIME-')layout = [[psg.Text('变倍方向:'), zoom_dir, psg.Text(" 倍率:"), zoom_time],[psg.Button('Exit', size=(10, 1))]
]
window = psg.Window('GUI测试', layout, font='_ 18', size=(500, 120))last_zoom_time = None
last_dir = Nonewhile True:event, values = window.read()if event == 'Exit' or event == psg.WIN_CLOSED:breakprint(f"event:{event}")if event == "-ZOOM DIR-":if last_dir == values['-ZOOM DIR-']:if values['-ZOOM DIR-'] == zoom_directions[0]:window['-ZOOM DIR-'].update(zoom_directions[1])else:window['-ZOOM DIR-'].update(zoom_directions[0])# print(f" direction:{window['-ZOOM DIR-'].get()}")elif event == "-ZOOM TIME-":if last_zoom_time == values['-ZOOM TIME-']:if values['-ZOOM TIME-'] == zoom_times[0]:window['-ZOOM TIME-'].update(zoom_times[2])else:window['-ZOOM TIME-'].update(zoom_times[0])# print(f" times:{window['-ZOOM TIME-'].get()}")last_dir = window['-ZOOM DIR-'].get()last_zoom_time = window['-ZOOM TIME-'].get()window.close()
