一.搭建环境
- 1.python官网下载python3.7.4 安装
https://www.python.org/ftp/python/3.7.4/python-3.7.4.exe
-
2.命令行安装PySide2
pip install PySide2 -
3.安装qt 5.13
参考帖子
二、创建demo程序
- 1.打开qt 5.13，创建Qt for Python - Windows 程序
- 2.在main.py里追加如下代码
追加导入
# This Python file uses the following encoding: utf-8
import sys
import random
from PySide2 import QtCore, QtWidgets, QtGui
定义MyWidget类
class MyWidget(QtWidgets.QWidget):
def __init__(self):
super().__init__()
self.hello = ["Hallo Welt", "Hei maailma", "Hola Mundo", "Привет мир"]
self.button = QtWidgets.QPushButton("Click me!")
self.text = QtWidgets.QLabel("Hello World")
self.text.setAlignment(QtCore.Qt.AlignCenter)
self.layout = QtWidgets.QVBoxLayout()
self.layout.addWidget(self.text)
self.layout.addWidget(self.button)
self.setLayout(self.layout)
self.button.clicked.connect(self.magic)
def magic(self):
self.text.setText(random.choice(self.hello))
添加main函数，显示窗口
if __name__ == "__main__":
app = QtWidgets.QApplication([])
widget = MyWidget()
widget.resize(800, 600)
widget.show()
sys.exit(app.exec_())
