How to use Pyqt5 to set system clipboard and quit as soon as possible? QCoreApplication doesn't come with clipboard support, so the choice should be QApplication.

The following code is not working without starting event loop app.exec_(). But all I need is to set the clipboard and quit the script as soon as possible.

import sys
from PyQt5.QtWidgets import QApplication
app = QApplication([])
app.clipboard().setText('test')
# sys.exit(app.exec_())

I follow the instruction from How can I disable clear of clipboard on exit of PyQt application.

The following two methods don't work either.

from PyQt5.QtWidgets import QApplication
from PyQt5.QtCore import QEvent

app = QApplication([])
cb = QApplication.clipboard()
cb.setText('test01')
event = QEvent(QEvent.Clipboard)
app.sendEvent(cb, event)
app.processEvents()

import sys
from PyQt5.QtWidgets import QApplication
from PyQt5.QtCore import QEvent, QTimer

app = QApplication([])
cb = QApplication.clipboard()
cb.setText('test02')
QTimer.singleShot(0, app.quit)
sys.exit(app.exec_())

  @ekhumoro I am not so sure it is duplicated.The other two address on preserve copied data after quit. My problem is I run the script from Windows command line, don't want to invoke the event loop (quit the script as soon as possible), without mannully closing the app.

  Try adding app.processEvents() at the end. Alternatively, you could add QTimer.singleShot(0, app.quit); app.exec(), which will automatically terminate the event-loop. But that assumes the QEvent hack still works in Qt5. If not, you'll have to forget about PyQt and use some other third-party clipboard solution.
