代码

from PyQt5.QtWidgets import *
import sys

class pushButton(QWidget):
    def __init__(self):
        super(pushButton,self).__init__()
        # 对方法进行调用
        self.initUI()


    def initUI(self):
        # 设置为水平布局
        layout=QHBoxLayout()
        # 实例化按钮
        button1 = QPushButton('按钮1')
        button2 = QPushButton('按钮2')
        button3 = QPushButton('关闭')
        # 设置点击事件
        button1.clicked.connect(self.click)
        button2.clicked.connect(self.click)
        button3.clicked.connect(self.close)
        # 设置文本接收框
        self.textEdit=QTextBrowser()
        # 布局到窗口上
        layout.addWidget(button1)
        layout.addWidget(button2)
        layout.addWidget(button3)
        layout.addWidget(self.textEdit)
        # 添加布局到布局上
        self.setLayout(layout)
    def click(self):
        # 获取信号与槽
        button = self.sender()
        print(button.text())
        # 获取 TextEdit的被设置的text值
        self.textEdit.setText("点击了"+button.text())

if __name__ == '__main__':
