From 300534fc214f2547a63594ce0891e9a54c8f33ca Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Samuel=20R=C3=B8dal?= Date: Wed, 31 Oct 2012 12:32:31 +0100 Subject: Added MultipleWindows platform capability. Several platform plugins, like eglfs, kms, etc don't support multiple windows as there's no system compositor, they're rendering directly to a single back buffer. By adding a platform capability we'll be able to provide better error reporting when an application tries to create multiple QWindows on a single-window platform. Also, QML apps can use this capability to figure out whether they should create a QWindow for dialogs / popups / menus, or whether to just create items in the same scene, that are shown on top of the rest of the content.
