From 8d72aba9e3358fdf51578533ab7f46602f7fd103 Mon Sep 17 00:00:00 2001 From: Laszlo Agocs Date: Sun, 12 Feb 2017 15:08:52 +0100 Subject: Introduce QVulkanWindow A convenience subclass of QWindow that provides a Vulkan-capable window with a double-buffered FIFO swapchain. While advanced use cases are better served by a custom QWindow subclass, many applications can benefit from having a convenient helper that makes getting started easier. Add also three examples of increasing complexity, and a variant that shows embeddeding into widgets via QWindowContainer. [ChangeLog][QtGui] Added QVulkanWindow, a convenience subclass of QWindow.
