PyQt：在Windows中为我的程序做“启动时启动”技巧的最佳方法

import sys
from PyQt4.QtCore import QSettings
from PyQt4.QtGui import (QApplication, QWidget, QCheckBox, QPushButton,
                         QVBoxLayout)

RUN_PATH = \"HKEY_CURRENT_USER\\\\Software\\\\Microsoft\\\\Windows\\\\CurrentVersion\\\\Run\"

class MainWidget(QWidget):

    def __init__(self,parent=None):
        super(MainWidget, self).__init__(parent)
        self.settings = QSettings(RUN_PATH, QSettings.NativeFormat)
        self.setupUi()       
        # Check if value exists in registry
        self.checkbox.setChecked(self.settings.contains(\"MainWidget\"))

    def setupUi(self):
        self.checkbox = QCheckBox(\"Boot at Startup\", self)
        button = QPushButton(\"Close\", self)
        button.clicked.connect(self.close)
        layout = QVBoxLayout(self)
        layout.addWidget(self.checkbox)
        layout.addWidget(button)

    def closeEvent(self, event):
        if self.checkbox.isChecked():
            self.settings.setValue(\"MainWidget\",sys.argv[0]);
        else:
            self.settings.remove(\"MainWidget\");
        event.accept()

if __name__ == \'__main__\':
    app = QApplication(sys.argv)
    w = MainWidget()
    w.show()
    app.exec_()
