Qt5Reactor

Using the Qt5Reactor

Qt5Reactor is compatible with both PyQt5 and PySide2.

Install using pip

pip install qt5reactor

Before running / importing any other Twisted code, invoke:

app = QApplication(sys.argv) # your code to init QtCore
from twisted.application import reactors
reactors.installReactor('qt5')

or

app = QApplication(sys.argv) # your code to init QtCore
import qt5reactor
qt5reactor.install()

Testing

trial --reactor=qt5 [twisted] [twisted.test] [twisted.test.test_internet]

Make sure the plugin directory is in path or in the current directory for reactor discovery to work.

There is also pytest-twisted for use with pytest. You can specify to use the qt5reactor by adding --reactor=qt5reactor.
