def __init__(self, useGtk=False): (source)
overrides twisted.internet._glibbase.GlibReactorBase.__init__

Undocumented

def registerGApplication(self, app): (source)

Register a Gio.Application or Gtk.Application, whose main loop will be used instead of the default one.

We will hold the application so it doesn't exit on its own. In versions of python-gi 3.2 and later, we exit the event loop using the app.quit method which overrides any holds. Older versions are not supported.

_crash = (source)
overrides twisted.internet._glibbase.GlibReactorBase._crash

Undocumented

_gapplication = (source)

A Gio.Application instance that was registered with registerGApplication.

_run = (source)
