在PyQt中实现首选项对话框窗口

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

class PreferencesDialog(QDialog):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("首选项")
        self.initUI()

    def initUI(self):
        layout = QVBoxLayout()
        formLayout = QFormLayout()

        # 添加首选项选项
        label1 = QLabel("选项1:")
        lineEdit1 = QLineEdit()
        formLayout.addRow(label1, lineEdit1)

        label2 = QLabel("选项2:")
        lineEdit2 = QLineEdit()
        formLayout.addRow(label2, lineEdit2)

        # 添加确定和取消按钮
        buttonBox = QPushButton("确定")
        buttonBox.clicked.connect(self.accept)
        formLayout.addRow(buttonBox)

        layout.addLayout(formLayout)
        self.setLayout(layout)

if __name__ == '__main__':
    app = QApplication([])
    dialog = PreferencesDialog()
    dialog.exec_()
