* QVulkanWindow: return QMatrix4x4 by valueMarc Mutz2017-05-221-3/+3
| | | | | | | The function never returns nullptr, so return the matrix by value. Change-Id: I7c1eeb43b9693866049763565b575348ddd35548 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>
* QVulkanWindow: use QVector, not QSet, for small int setMarc Mutz2017-05-221-4/+5
| | | | | | | | | | Apart from being more efficient to construct and test, for the expected very small number of entries, the example code itself shows that a sorted vector is much more useful than an unordered set.

* QVulkanWindow: fix fatal warning on Clang 4Shawn Rutledge2017-05-031-1/+1
| | | | | | | | | | | | | | | qtbase/src/gui/vulkan/qvulkanwindow.cpp:1882:42: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] VkClearColorValue clearColor = { 0.0f, 0.0f, 0.0f, 1.0f }; ^~~~~~~~~~~~~~~~~~~~~~ { } 1 error generated. VkClearColorValue is a union, so it wants to be clear that we are initializing only one of the union's members, apparently. (Even though initing more than one wouldn't make sense.)

* doc: Fix several qdoc warnings in new softwareMartin Smith2017-03-311-34/+40
| | | | | | | | | | This change fixes several common qdoc warnings in this new software. However, because vulkan/vulkan.h is not always available, a few typedefs were also added to define some standard vulkan types for clang to see when vulkan.h is not available.

* Clarify the front face winding order in the Vulkan examplesLaszlo Agocs2017-03-261-0/+4
| | | | | | | | | After applying the correction matrix the front face is CW, not CCW. The examples work either way but fix them up to avoid reader confusion. Change-Id: I491e6dc17c21897a59f36d32061e937f2b6c4c9d Reviewed-by: Andy Nichols <andy.nichols@qt.io>
* QVulkanWindow: Add missing device wait after user codeLaszlo Agocs2017-03-261-6/+17
| | | | | | | | | | In a multi-threaded setup it is not unlikely that releaseSwapChainResources() will wait for and submit any remaining frame building. Hence a wait is necessary also after invoking the user's implementation. Change-Id: I3c963c05c1c3981980da5e4ff9c572df24a1e473 Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* Introduce QVulkanWindowLaszlo Agocs2017-03-221-0/+2678
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.
