* Add VulkanMemoryAllocatorLaszlo Agocs2019-06-126-0/+17242
| | | | | | | | | | | | | | | | | | | | | | | | The Vulkan backend of QRhi relies on vk_mem_alloc.h from AMD in order to get a stable, performant, and tested GPU memory allocator. It is not unthinkable that we will move away from this in the future, especially considering that a potential future D3D12 backend may need a similar solution, but until then this will do.

* Introduce the Qt graphics abstraction as private QtGui helpersLaszlo Agocs2019-06-1330-0/+29414
| | | | | | | | | | | | | | | | | | | | | | Comes with backends for Vulkan, Metal, Direct3D 11.1, and OpenGL (ES). All APIs are private for now. Shader conditioning (i.e. generating a QRhiShader in memory or on disk from some shader source code) is done via the tools and APIs provided by qt-labs/qtshadertools. The OpenGL support follows the cross-platform tradition of requiring ES 2.0 only, while optionally using some (ES) 3.x features. It can operate in core profile contexts as well.

* Avoid uninitialized texture data in image glyph cacheLaszlo Agocs2019-05-281-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem becomes visible with styled native text materials in Quick, but only in certain cases: the regions not used by glyphs in the QImage are undefined (if they are 0 there's no problem) - but the whole code path is only used when the fbo readback workaround is enabled. When these conditions met, the styled text materials may sample locations with uninitialized data in the texture, showing small artifacts around the glyphs when shifting is involved in the styling. The non-image based GL glyph cache handles this by an explicit upload with all 0's when creating the texture - the QImage code path should do the same then.

* Remove the last uses of Java-style iterators in QtCoreMarc Mutz2019-05-232-12/+11
| | | | | | | | | | | | | | | | | | | | They are going to be deprecated. Add a strategic break. This was a pre-existing problem: the comment claims that h is invalid (though I personally don't see it), but then goes on to check the loop condition (which, in the mutable Java iterator case, involves calling h.cend()). We now cache the end iterator, so if there ever was a problem, it's probably a lesser one now, but it's still not kosher, and a debug version of QHash would find it, so break out explicitly. Saves ~200b in text size on optimized GCC 9.1 Linux AMD64 builds, ie. ~100b per loop. Change-Id: I7684485b55fb23a8cf882f89621ebb75a0e607b5 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | The check was a misnomer -- non-POD types can go in unions since C++11. And we may want them, e.g. types without a trivial default constructor. What we really want is to check for a literal type (so that the array payload can be built entirely at compile time, and put in .rodata). So, amend the check. Also, make the dummy array constexpr, to be sure that we are indeed building the payload using constexpr constructors. That would make the first check redundant, but the fact that we're still using a macro for constexpr makes me think that not all compilers support it, so I'm leaving the first check in...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Plain load() / store() have already relaxed semantics. This can be surprising -- std::atomic::load()/store() are actually sequentially consistent -- and introduce a pain point if someone wants to move from Qt atomics to std:: atomics. So just add a suffix to the functions to clarify what's the memory ordering involved with them. The Ops::load / ::store are temporarily left in, because other modules depends on them. We need to port those modules away, then they can go (it's private API anyhow). Similarly, not deprecating anything yet, except for marking obsolete in the docs; there's a lot of code around using load() / store() that needs to be ported first.

* Markdown and HTML: support image alt text and titleShawn Rutledge2019-06-019-12/+48
| | | | | | | | | | | | | | | | | | | | | It's a required CommonMark feature: https://spec.commonmark.org/0.29/#images and alt text is also required in HTML: https://www.w3.org/wiki/Html/Elements/img#Requirements_for_providing_text_to_act_as_an_alternative_for_images Now we are able to read these attributes from either html or markdown and rewrite either an html or markdown document that preserves them. This patch does not add viewing or editing support in QTextEdit etc. Change-Id: I51307389f8f9fc00809808390e583a83111a7b33 Reviewed-by: Gatis Paeglis <gatis.paeglis@qt.io>
* QGraphicsWidget: overload two margins-setters with actual QMarginsF overloadsMarc Mutz2019-05-274-60/+67
| | | | | | | | | | | | | | | | | | Replace manual memory management with unique_ptr and manual re-implementations of QMarginsF with The Real Thing™. The only noticeable difference should be that the checks for 0 now use qFuzzyCompare() (by way of QMarginsF::isNull() and its operator==). [ChangeLog][QtWidgets][QGraphicsWidget] Added QMarginsF overloads of setContentsMargins() and setWindowFrameMargins().

* QTextBrowser: detect and load markdown rather than assuming HTMLShawn Rutledge2019-05-303-1/+21
| | | | | | | | | | | | | | | | So we add the QTextDocument::ResourceType::MarkdownResource enum value to indicate the type. QMimeDatabase is generally unable to detect markdown by "magic", so we need to use the common file extensions to detect it (the same extensions as declared in the mime database XML).

* QEventDispatcherWin32: rework sending of posted eventsAlex Trotsenko2019-05-252-70/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since its initial implementation, QEventDispatcherWin32 manages a delivery of the posted events from the window procedure through WM_QT_SENDPOSTEDEVENTS message. That makes the implementation quite difficult and unclear. As a result, posted events get stalled, in case of using nested event loops or other recursion. The proposed solution is to send posted events at the beginning of processEvents() only once per iteration of the event loop. However, in case of using a foreign event loop (e.g. by opening a native modal dialog), we should leave the emission in the window procedure, as we don't control its execution.
