PyQT5之使用QT?Designer創(chuàng)建基本窗口方式

更新時間：2023年02月24日 08:35:58 作者：Trivis?Kylee

這篇文章主要介紹了PyQT5之使用QT?Designer創(chuàng)建基本窗口方式，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

環(huán)境配置

pip install pyqt5 （安裝pyQT5庫）：pyuic5包含在內(nèi)
pip install pyqt5-tools （安裝QT-Designer）

使用QT Designer布局窗體

UI文件的編譯

將.UI文件編譯為.PY文件(CMD命令行中)：

pyuic5 xxx.ui -o xxx.py  
 
#不可以存在中文！

打開編譯后的.py文件，新建SLOT()函數(shù)并修改連接函數(shù)：

在末尾添加運行代碼：

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_())

編譯后的.PY源碼
