From caab0ad35799df3b2059bd3707b727dc0b5671aa Mon Sep 17 00:00:00 2001 From: Friedemann Kleint Date: Mon, 13 Jan 2020 11:20:14 +0100 Subject: Fix Mandelbrot Example documentation with regards to qRegisterMetaType() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The call to qRegisterMetaType() has been removed since the type is registered as a meta type in Qt 5. Assert on the meta type id instead. Adapt the documentation accordingly.
