仅将信号绑定到插槽似乎不起作用，并且没有出现任何错误。打印消息也不在该功能中起作用。

我无法运行您的代码，但是主要问题似乎是缩进不正确。只有您的clicked.connect调用应该在构造函数中（在所有其他方法之上），在其他方法之外。请参阅以下可运行模板以了解代码的结构：
import sys
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
class Window(QWidget):
def __init__(self, *args, **kwargs):
QWidget.__init__(self, *args, **kwargs)
self.button1 = QPushButton("Test 1", self)
self.button2 = QPushButton("Test 2", self)
self.button3 = QPushButton("Test 3", self)
self.layout = QHBoxLayout()
self.layout.addWidget(self.button1)
self.layout.addWidget(self.button2)
self.layout.addWidget(self.button3)
self.setLayout(self.layout)
self.show()
self.button1.clicked.connect(self.on_button1)
self.button2.clicked.connect(self.on_button2)
self.button3.clicked.connect(self.on_button3)
@pyqtSlot()
def on_button1(self):
print("Button #1")
@pyqtSlot()
def on_button2(self):
print("Button #2")
@pyqtSlot()
def on_button3(self):
print("Button #3")
if __name__ == "__main__":
app = QApplication(sys.argv)
win = Window()
sys.exit(app.exec_())
使用按下的连接。这次应该可以工作。
