如何更改pysimplegui中显示的图像
如何更改pysimplegui中显示的图像
提问于 2022-09-12 11:20:25
我按照下面的代码创建了GUI。通过单击图像按钮将显示的图像更改为新图像是否可行，以便在表单更新时保存新图像？此外，在上传更新(和保存)表单后，只显示已填充的字段是否可行？提前感谢

这里有一个简单的脚本，仅用于演示，只有一个Image元素可以保存并加载到GUI中。
import json
from pathlib import Path
import PySimpleGUI as sg
settings_file = 'settings.json'
settings = {'-Image-':None}
if Path(settings_file).is_file():
with open(settings_file, 'rt') as f:
settings = json.load(f)
layout = [
[sg.FileBrowse(target='Browse', enable_events=True, key='Browse')],
[sg.Image(filename=settings['-Image-'], visible=(settings['-Image-'] is not None), key='-Image-')],
]
window = sg.Window('Window Title', layout)
while True:
event, values = window.read()
if event == sg.WIN_CLOSED:
break
elif event == 'Browse':
filename = values['Browse']
window['-Image-'].update(filename=filename, visible=True)
window.refresh()
window.move_to_center()
settings['-Image-'] = filename
with open(settings_file, 'wt') as f:
json.dump(settings, f)
