代码完成后 Tkinter 窗口打开

Question

我刚刚开始使用声卡 python 模块的基本功能。但是，我无法让我的 tkinter 窗口首先显示，然后等到按下运行按钮来执行“def run()”代码。它总是先执行“def run()”代码，然后打开窗口。我究竟做错了什么？

from tkinter import *

import soundcard as sc

window = Tk()

window.geometry("500x500")

window.title("Virtual Soundcard")

default_speaker = sc.default_speaker()

default_mic = sc.default_microphone()

def run():

    with default_mic.recorder(samplerate=44100) as mic, \

        default_speaker.player(samplerate=44100) as sp:

        for val in range(100):

            data = mic.record(numframes=None)

            sp.play(data)

RunButton = Button(window, text ="Run", command = run())

RunButton.pack()

RunButton.place(x = 100, y = 250)

window.mainloop()

Answer 1

更改RunButton = Button(window, text ="Run", command = run())为RunButton = Button(window, text ="Run", command = run)基本上删除()命令参数，()甚至在按下按钮之前（即在代码执行时）调用该函数。希望这能解决这个错误。如有任何疑问或错误，请告诉我。干杯
