如何将生成的UI文件转化为py代码

pyuic5 main.ui -o main.py

好的，下面是一个简单的文件处理程序页面的设计代码示例：

文件处理示例

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QVBoxLayout, QHBoxLayout, QLabel, QLineEdit, QPushButton, QTextEdit, QFileDialog


class FileProcessor(QMainWindow):
    def __init__(self):
        super().__init__()
        self.initUI()


    def initUI(self):
        # 设置窗口标题
        self.setWindowTitle('文件处理程序')


        # 创建主窗口部件
        main_widget = QWidget()
        self.setCentralWidget(main_widget)


        # 创建垂直布局
        vbox = QVBoxLayout()


        # 创建水平布局
        hbox1 = QHBoxLayout()
        hbox2 = QHBoxLayout()


        # 添加标签和文本框到第一行水平布局
        label1 = QLabel('输入文件路径：')
        self.input_path = QLineEdit()
        hbox1.addWidget(label1)
        hbox1.addWidget(self.input_path)


        # 添加打开文件按钮到第一行水平布局
        open_button = QPushButton('打开文件')
        open_button.clicked.connect(self.open_file_dialog)
        hbox1.addWidget(open_button)


        # 添加标签和文本框到第二行水平布局
        label2 = QLabel('输出文件路径：')
        self.output_path = QLineEdit()
        hbox2.addWidget(label2)
        hbox2.addWidget(self.output_path)


        # 添加保存文件按钮到第二行水平布局
        save_button = QPushButton('保存文件')
        save_button.clicked.connect(self.save_file_dialog)
        hbox2.addWidget(save_button)


        # 添加两个水平布局到垂直布局
        vbox.addLayout(hbox1)
        vbox.addLayout(hbox2)


        # 添加文本框到垂直布局
        self.text_edit = QTextEdit()
        vbox.addWidget(self.text_edit)


        # 设置主窗口部件的布局
        main_widget.setLayout(vbox)


    def open_file_dialog(self):
        # 打开文件对话框
        file_path, _ = QFileDialog.getOpenFileName(self, '打开文件', '', 'Text Files (*.txt);;All Files (*)')
        if file_path:
            self.input_path.setText(file_path)


    def save_file_dialog(self):
        # 保存文件对话框
        file_path, _ = QFileDialog.getSaveFileName(self, '保存文件', '', 'Text Files (*.txt);;All Files (*)')
        if file_path:
            self.output_path.setText(file_path)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    fp = FileProcessor()
    fp.show()
    sys.exit(app.exec_())
