class UserActionContext(object): (source)

Context manager to wrap actions in proper user-action signals

This class used for the TextBuffer.user_action attribute

This allows syntax like:

        with buffer.user_action:
                buffer.insert(...)

instead off:

        buffer.begin_user_action()
        buffer.insert(...)
        buffer.end_user_action()

By wrapping actions in this "user-action" block the UndoStackManager will see it as a single action and make it undo-able in a single step.
