From a3220e460bdcb9bc878bfe37721a7798ac8c2d64 Mon Sep 17 00:00:00 2001 From: Shawn Rutledge Date: Mon, 5 Nov 2012 11:04:21 +0100 Subject: qmlscene can start with either an Item or Window as the qml root MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Before, it assumed that the root is an Item and needs to have a Window created. But it's useful for an application to have a Window as the root, and it was already possible by writing a different C++ main function (see qtdeclarative/examples/window/window/window.cpp). It doesn't take much to give qmlscene this flexibility too.
