PyQt进阶UI

一、选择按钮

1. 单选框

• 无默认选项情况下

程序源码

import sys
from PyQt5.QtWidgets import QApplication, QWidget , QRadioButton

if __name__=='__main__':
    app = QApplication(sys.argv)

    w = QWidget()

    # 设置窗口标题、窗口大小
    w.setWindowTitle("单选框")
    w.resize(400,300)

    # 创建单选框并设置单选框的位置及大小
    radio_btn_eating = QRadioButton("去吃饭",w)
    radio_btn_eating.setGeometry(20,20,100,20)

    radio_btn_studying = QRadioButton("去学习",w)
    radio_btn_studying.setGeometry(125,20,100,20)

    w.show()

    app.exec()
