From 2ca20724dd17df96143be160505f982ab6cf4378 Mon Sep 17 00:00:00 2001 From: Samuel Nevala Date: Tue, 17 Nov 2015 07:52:28 +0200 Subject: WinRT: Add camera button events on Windows Phone MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Windows Phone 8.1 provides access to the camera button and press/release events get passed as Key_CameraFocus and Key_Camera. Unfortunately a release does not provide what has been pressed before, hence this information needs to be cached when the press happens.
