From 7440630caa77869e7d264dfb9da47db2182524a2 Mon Sep 17 00:00:00 2001 From: Doug Zongker Date: Fri, 28 Oct 2011 15:13:10 -0700 Subject: refactor ui functions into a class Move all the functions in ui.c to be members of a ScreenRecoveryUI class, which is a subclass of an abstract RecoveryUI class. Recovery then creates a global singleton instance of this class and then invoke the methods to drive the UI. We use this to allow substitution of a different RecoveryUI implementation for devices with radically different form factors (eg, that don't have a screen).
