From 8342382e238fd7d70e356cf69e4399fee85848d9 Mon Sep 17 00:00:00 2001 From: Oliver Wolff Date: Tue, 27 Mar 2018 14:07:10 +0200 Subject: qtmain_winrt: Synchronize debug message calls MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When winrtrunner is used to debug winrt applications, debug messages should be acknowledged by winrtrunner. Otherwise it is possible, that 2 messages are sent (and their event set) before winrtrunner reacted. In this case the first message was lost and the second message shown twice.
