From ccfeac7d1e474408e2cae169714326f6198eb17c Mon Sep 17 00:00:00 2001 From: Jocelyn Turcotte Date: Mon, 5 Aug 2013 16:37:31 +0200 Subject: Import the demo browser into widget examples. Import the sources as-is, without adding it to the build, to allow performing diffs later on the changes that were needed to port it to use QtWebEngine and manage source compatibility issues.
