PyQT5之使用QT Designer创建基本窗口方式
目录
环境配置
使用QT Designer布局窗体
UI文件的编译
编译后的.PY源码
运行结果
总结
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
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_())
编译后的.PY源码

以上为个人经验，希望能给大家一个参考，也希望大家多多支持软件开发网。
