python中多個QPushButton響應同一個事件
注：在python2 的環境下執行

#! -*- coding:utf-8 -*-
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QHBoxLayout, QPushButton
import sys
class WindowDemo(QWidget):
    def __init__(self):
        super(WindowDemo, self).__init__()
        btn1 = QPushButton(u'單一儲存', self)
        btn2 = QPushButton(u'連續儲存', self)
        btn3 = QPushButton(u'暫停連續儲存', self)
        btn1.clicked.connect(self.handle_camsave)
        btn2.clicked.connect(self.handle_camsave)
        btn3.clicked.connect(self.handle_camsave)
        hbox = QHBoxLayout()
        hbox.addWidget(btn1)
        hbox.addWidget(btn2)
        hbox.addWidget(btn3)
        hbox.addStretch(0)
        self.setLayout(hbox)
        self.setWindowTitle("addStretch 例子")
    def handle_camsave(self):

        sender = self.sender()
        clickevent = sender.text()
        if clickevent == u'單一儲存':
            print(u'單擊了第一個按鈕')
        elif clickevent == u'連續儲存':
            print(u'單擊了第二個按鈕')
        else:
            print(u'單擊了第三個按鈕')

if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = WindowDemo()
    win.show()
    sys.exit(app.exec_())

 

效果圖如下所示：
