问题 When calling a function via a signal connection as in mybutton.clicked.connect(myfunction) the function is called with all its arguments set to False. Even though default arguments have been set. Is this the expected behavior? The code below shows a simple example. For my particular case having all arguments set to False is not a big issue as I can simply catch it with an if statement. However I feel that knowledge on why it is implemented this way may be helpful for further projects. This

问题 I am trying to create a floating browser for youtube and other media.

Should I terminate the worker first and then the thread? How can I terminate the worker anyway? import sys from PyQt5.QtWidgets import (QWidget, QPushButton, QApplication, QGridLayout) from PyQt5.QtCore import QThread,
