Connect Function In Pyqt5 Does Not Work

I recently moved from pyside to pyqt5 and there is a problem. I looked it up online and apparently, it already happened to people who used pyqt4 and moved to pyqt5. However, it did

Solution 1:

from the docs:

connect(slot[, type=PyQt5.QtCore.Qt.AutoConnection[, no_receiver_check=False]])

Connect a signal to a slot. An exception will be raised if the connection failed. Parameters:

• slot – the slot to connect to, either a Python callable or another bound signal.
• type – the type of the connection to make.
• no_receiver_check – suppress the check that the underlying C++ receiver instance still exists and deliver the signal anyway.

for your example:

self.buttonBox.accepted.connect(Dialog.accept) # pyqt5

QtCore.QObject.connect(self.buttonBox.rejected, Dialog.reject) # pyqt4

_{As a sidenote, "Dialog" sounds like a class, you probably want to connect to an instance, else think about naming your instances with lowercase front-letters ...}
