我想使用 PySimpleGUI 創建一個進度條，但我希望用戶放置進度條的最大值。這是我的代碼：
import PySimpleGUI as sg
import random, time
sg.theme("LightBlue")
progress_value=input()
layout = [[sg.Text("Enter a number out of 50", font='Lucida'),
sg.InputText(key='-PROGRESS_VALUE-', font='Lucida, 20', size=(20, 40))],
[sg.ProgressBar(progress_value, orientation='h', size=(100, 20), border_width=4, key='-PROGRESS_BAR-',
bar_color=("Blue", "Yellow"))],
[sg.Button('Change Progress'), sg.Exit(),sg.Button('Stop Progress')]]
window = sg.Window("Progress Bar", layout)
while True:
event, values = window.read()
if event == 'Exit' or event == sg.WIN_CLOSED:
break
progress_value = int(values['-PROGRESS_VALUE-'])
if event == "Change Progress":
for i in range(progress_value):
event, values = window.read(1000)
if event == "Stop Progress":
window['-PROGRESS_BAR-'].update(i-1)
break
window['-PROGRESS_BAR-'].update(max=progress_value)
window['-PROGRESS_BAR-'].update(i 1)
window.close()
如您所見，“progress_value”的最大值由 an 給出，input (progress_value=input())
但我希望它來自用戶的輸入文本，(sg.InputText(key='-PROGRESS_VALUE-', font='Lucida, 20', size=(20, 40)))并且該值將設定為 progress_value
uj5u.com熱心網友回復：
這是使用單個事件回圈后做你正在做的事情的一種方法
更改 ProgressBar 的最大值時，您也必須設定當前值（在同一個更新呼叫中）。
import PySimpleGUI as sg
sg.theme("LightBlue")
progress_value = 50
layout = [[sg.Text("Enter a number out of 50", font='Lucida'),
sg.InputText(key='-PROGRESS_VALUE-', font='Lucida, 20', size=(20, 40))],
[sg.ProgressBar(progress_value, orientation='h', size=(100, 20), border_width=4, key='-PROGRESS_BAR-',
bar_color=("Blue", "Yellow"))],
[sg.Button('Change Progress'), sg.Button('Start Progress'), sg.Button('Stop Progress')]]
window = sg.Window("Progress Bar", layout)
progress_started, counter, timeout = False, 0, None
while True:
event, values = window.read(timeout=timeout)
if event == 'Exit' or event == sg.WIN_CLOSED:
break
if event == "Change Progress":
progress_value = int(values['-PROGRESS_VALUE-'])
# NOTE - must set a current count when changing the max value
window['-PROGRESS_BAR-'].update(current_count= 0, max=progress_value)
elif event == 'Start Progress':
progress_started = True
counter = 0
timeout = 1000
elif event == 'Stop Progress':
progress_started = False
timeout = None
if progress_started:
window['-PROGRESS_BAR-'].update(counter)
counter = 1
if counter > progress_value:
progress_started = False
window.close()
