From 4a80a7ced1f643a6794f6550d01c1fe60295a21c Mon Sep 17 00:00:00 2001 From: Rick Stockton Date: Mon, 6 Feb 2012 17:20:08 -0800 Subject: add widget mousebuttons example 'mousetester'. This is an xev-like program. A user clicks a mouse button inside the Window, and the program displays (a) the "raw" button number; (b) the corresponding Qt::MouseButton name; and (c) the type of mouse Event.
