[PyQt] slot of QClipboard::dataChanged() was called twice

[Zhao Lee]

As tested With PyQt5.7,Python3.5 on Win7 32bit,
the slot detectClipboardUrl of QClipboard::dataChanged() was called twice In this code, while I need the slot to be called only once , any solutions ?


import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *




class MainWindow(QTableView):


    def __init__(self, parent=None):
        super().__init__(parent)
        self.clipboard = QApplication.clipboard()
        self.clipboard.dataChanged.connect(self.detectClipboardUrl)  


    @pyqtSlot()
    def detectClipboardUrl(self):
    print('detectClipboardUrl')
    clipboardText = self.clipboard.text()
    print(clipboardText)




if __name__ == "__main__":
    app = QApplication(sys.argv)
    ui = MainWindow()
    ui.show()
    sys.exit(app.exec_())
