环境配置

• pip install pyqt5 （安装pyQT5库）：pyuic5包含在内
• pip install pyqt5-tools （安装QT-Designer）

使用QT Designer布局窗体

UI文件的编译

将.UI文件编译为.PY文件(CMD命令行中)：

pyuic5 xxx.ui -o xxx.py  
 
#不可以存在中文！

打开编译后的.py文件，新建SLOT()函数并修改连接函数：

在末尾添加运行代码：

if __name__ == \"__main__\":    
	import sys    
	app = QtWidgets.QApplication(sys.argv)    
	MainWindow = QtWidgets.QMainWindow()    
	ui = Ui_MainWindow()    
	ui.setupUi(MainWindow)    
	MainWindow.show()    
	sys.exit(app.exec_())
