sas.qtgui.Utilities.ReactorCore module

This module provides support for Twisted to be driven by the Qt mainloop.

In order to use this support, simply do the following::
app = QApplication(sys.argv) # your code to init Qt
import qt5reactor
qt5reactor.install()

Then use twisted.internet APIs as usual. The other methods here are not intended to be called directly.

If you don’t instantiate a QApplication or QCoreApplication prior to installing the reactor, a QCoreApplication will be constructed by the reactor. QCoreApplication does not require a GUI so trial testing can occur normally.

Twisted can be initialized after QApplication.exec_() with a call to reactor.runReturn(). calling reactor.stop() will unhook twisted but leave your Qt application running
