From b6f7fe1f80e6beed62ef47691fae6aa9f4a851b8 Mon Sep 17 00:00:00 2001 From: Venugopal Shivashankar Date: Wed, 3 Oct 2018 13:50:13 +0200 Subject: Examples: Use XmlHttpRequest to fetch flickr public photos This change is to facilite moving the XmlListModel code to the qtxmlpatterns repo, but still keep all the Particles examples together. Also fixed: - the old TODO about darkening images according to depth, and make it generally look a bit better. - move the visualdatamodel examples to a directory called delegatemodel, since that's how they work now. And add them to the main "views" example launcher so that they become more visible to users.
