woo.ipythonintegration.create_inputhook_qt4(mgr, app=None)[source]

Create an input hook for running the Qt4 application event loop.

Parameters: mgr – an InputHookManager app – Qt Application, optional. Running application to use. If not given, we probe Qt for an existing application object, and create a new one if none is found. A pair consisting of a Qt Application (either the one given or the one found or created) and a inputhook.

Note

We use a custom input hook instead of PyQt4’s default one, as it interacts better with the readline packages (issue #481).

The inputhook function works in tandem with a ‘pre_prompt_hook’ which automatically restores the hook as an inputhook in case the latter has been temporarily disabled after having intercepted a KeyboardInterrupt.
