From 115f303352df90a0ceeea2af167a8592da33cd82 Mon Sep 17 00:00:00 2001 From: Alejandro Exojo Date: Sat, 31 Oct 2015 13:17:02 +0100 Subject: [PATCH] Fix the closeEvent of the systray example on OS X MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The implementation of the close event handler requires handling the two close events that are received on OS X when the user quits through the application menu bar or the Command+Q shortcut. The first is an spontaneous event, and the second a non-spontaneous one with the window already closed.
