我正在运行 PyQt6。我有一个 QMainWindow,在一个小部件中有一个 QPushButton 和 QLineEdit。每次单击该按钮时,我都想播放一个声音,并且同时它会在我的行编辑中添加一个文本。我曾经playsound
实现过这个效果,但是播放声音和添加文字时会有延迟。
我想消除这种延迟。我还发现在 PyQt4 中有 QSound 选项,但在 PyQt6 中不再存在。也许有替代品playsound
?
无论如何,这是我的代码:
import sys
from functools import cached_property, partial
from threading import Thread
from playsound import playsound
from PyQt6.QtCore import *
from PyQt6.QtGui import *
from PyQt6.QtWidgets import *
class Main(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle('Play Sound')
central_widget = QWidget()
self.setCentralWidget(central_widget)
self.btn = QPushButton()
self.lay = QHBoxLayout(central_widget)
self.btn.setText('Play the Sound')
self.lay.addWidget(self.btn)
self.qline = QLineEdit()
self.qline.setFixedHeight(35)
self.lay.addWidget(self.qline)
self.btn.clicked.connect(partial(self.buildExpression, 'X'))
self.btn.clicked.connect(self.playsound)
def line(self):
return self.qline.text()
def lineedit(self, text):
self.qline.setText(text)
self.qline.setFocus()
def buildExpression(self, sub_exp):
expression = self.line() + sub_exp
self.lineedit(expression)
def playsound(self):
playsound('sound.mp3')
def background():
while True:
playsound('background.mp3')
def main():
app = QApplication(sys.argv)
run = Main()
Thread(target=background, daemon=True).start()
run.show()
app.exec()
if __name__ == "__main__":
main()
