From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Kurtz Subject: [PATCH 7/8 v3] Input: add BTN_TOOL_QUINTTAP for reporting 5 fingers on touchpad Date: Sat, 13 Aug 2011 01:16:46 +0800 Message-ID: <1313169407-4358-8-git-send-email-djkurtz@chromium.org> References: <1313169407-4358-1-git-send-email-djkurtz@chromium.org> Return-path: In-Reply-To: <1313169407-4358-1-git-send-email-djkurtz@chromium.org> Sender: linux-kernel-owner@vger.kernel.org To: chase.douglas@canonical.com, dmitry.torokhov@gmail.com, rydberg@euromail.se Cc: linux-input@vger.kernel.org, linux-kernel@vger.kernel.org, olofj@chromium.org, chris@cnpbagwell.com, Daniel Kurtz List-Id: linux-input@vger.kernel.org "4-finger scroll" is a gesture supported by some applications and operating systems. "Resting thumb" is when a clickpad user rests a finger (e.g., a thumb), in a "click zone" (typically the bottom of the touchpad) in anticipation of click+move=select gestures. Thus, "4-finger scroll + resting thumb" is a 5-finger gesture. To allow userspace to detect this gesture, we send BTN_TOOL_QUINTTAP.
