从PyQt5 QDialog获取更改的数据

from PyQt5.QtWidgets import QApplication, QDialog, QLabel, QLineEdit, QPushButton, QVBoxLayout

class MyDialog(QDialog):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("My Dialog")
        
        # 创建控件
        self.label = QLabel("Name:")
        self.line_edit = QLineEdit()
        self.button = QPushButton("OK")
        
        # 设置布局
        layout = QVBoxLayout()
        layout.addWidget(self.label)
        layout.addWidget(self.line_edit)
        layout.addWidget(self.button)
        self.setLayout(layout)
        
        # 连接按钮的点击事件
        self.button.clicked.connect(self.on_button_clicked)
        
    def on_button_clicked(self):
        # 获取文本框的值
        name = self.line_edit.text()
        
        # 处理获取到的数据，例如打印到控制台
        print("Name:", name)
        
        # 关闭对话框
        self.accept()

# 创建应用程序和对话框实例
app = QApplication([])
dialog = MyDialog()

# 显示对话框
dialog.exec_()
