3、Qt- 将ui文件转为py文件后运行py程序

.ui转.py文件

• 先将生成的.ui文件转为.py文件
  

编辑.py文件

# Form implementation generated from reading ui file 'untitled.ui'
#
# Created by: PyQt6 UI code generator 6.4.2
#
# WARNING: Any manual changes made to this file will be lost when pyuic6 is
# run again.  Do not edit this file unless you know what you are doing.
import sys
 
from PyQt6 import QtCore, QtGui, QtWidgets
from PyQt6.QtWidgets import QWidget
 
 
# 创建ui类
class Ui_Form(object):
 
    # 创建ui的方法
    def setupUi(self, Form):
        Form.setObjectName("Form")  # 窗口名称
        Form.resize(400, 300)   # 窗口大小
        self.pushButton = QtWidgets.QPushButton(parent=Form)    # 创建按钮
        self.pushButton.setGeometry(QtCore.QRect(100, 120, 111, 41)) # 设置按钮位置
        self.pushButton.setObjectName("pushButton") # 按钮名称
 
        self.retranslateUi(Form)    # 设置按钮名称
        QtCore.QMetaObject.connectSlotsByName(Form) # 连接槽函数
 
    # 设置按钮名称
    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate  # 翻译
        Form.setWindowTitle(_translate("Form", "Form")) # 窗口名称
        self.pushButton.setText(_translate("Form", "pyqt6按钮")) # 按钮名称
 
 
if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
 
    # 创建窗口
    Form = QtWidgets.QWidget()
 
    # 创建ui类
    ui = Ui_Form()
    # 调用ui类
    ui.setupUi(Form)
    # 显示窗口
    Form.show()
    sys.exit(app.exec())
 

• 效果如下：
