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

[Zhao Lee]

 Someone says it is  a bug in Chromium 
http://stackoverflow.com/questions/39191394/slot-of-qclipboarddatachanged-was-called-twice
I write the slot of QClipboard::dataChanged() as this  to avoid the bug,
    @pyqtSlot()
    def detectClipboardUrl(self):
        clipboardText = self.clipboard.text()
        if getattr(self.clipboard, 'lastClipboardUrl', None) != clipboardText:
            url = clipboardText
            setattr(self.clipboard, 'lastClipboardUrl', url)

I made a solution for a similar problem with qscintilla - it      should be applicable here. Take a look at the mailing list entry      here:https://www.riverbankcomputing.com/pipermail/qscintilla/2016-May/001134.html

You could use a QTimer to delay and process only the              last change (maybe only in the case where a duplicate is              detected)
