持续更新 PySimpleGUI window

Question

I am creating a program in which i want to update values continuously after click start.

Until user clicks on Stop button i want values to keep updating

I use for loop for testing like

    for i in range(1000):
        window[-TEXT-].update(function())

Basically after the loop complete running it update the value directly last i value

I also use time.sleep(0.1) to keep track of it but didn't work

Answer 1

Call window[-TEXT-].update(function()) won't update the GUI, how to update GUI?

• Loop to next window.read()
• call window.Refresh() after it

You can use option timeout of window.read to count it if it is periodic.

count = 1000

while True:

    event, values = window.read(timeout=20)     # 20ms

    if event in (sg.WINDOW_CLOSED, 'Exit'):
        break

    elif event == sg.TIMEOUT_EVENT and count:
        window[-TEXT-].update(function())
        count -= 1

window.close()
