class UploadTaskQtThread(QtCore.QThread):
tick = QtCore.pyqtSignal(int, name="upload_changed")
def __init__(self, client, local_path, remote_path):
QtCore.QThread.__init__(self)
self.client = client
self.local_path = local_path
self.remote_path = remote_path
def on_progress(self, progress):
self.tick.emit(progress * 100)
def run(self):
self.client.upload_file(self.local_path, self.remote_path, self.on_progress)
Client:
def upload(self, local_file_path, remote_path):
self.upload_thread = UploadTaskQtThread(client, local_file_path, remote_path)
self.upload_thread.start()
self.upload_thread.tick.connect(ui.progressBar.setValue)
