* rhi: Remove Q_RELOCATABLE_TYPE for types with QVLA in themLaszlo Agocs2021-09-202-10/+1
| | | | | | | | | | | | | QVLA itself is non-relocatable due to self references. (ptr pointing to array[Prealloc] as long as capacity < Prealloc) Seems we shot ourselves in the foot in multiple places with this. Pick-to: 6.2 6.2.0 Fixes: QTBUG-96619 Change-Id: I57a2ce539b671326cd352dbe57a1f3d4c46a6456 Reviewed-by: Tobias Koenig <tobias.koenig@kdab.com> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Introduce QDoubleValidator::setRange overload with two parametersIvan Solovev2021-09-202-4/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QDoubleValidator::setRange() used to have 3 parameters, with the third one (the number of decimals) having a default value of 0. Such default value does not make much sense for a *double* validator. Also, since a default value was used, omitting the decimals was silently overwriting the previous decimals value, discarding the value that could be previously explicitly specified by user. [ChangeLog][QtCore][QDoubleValidator][Important Behavior Changes] The QDoubleValidator::setRange() method now has two overloads. The first overload takes 3 parameters, but does not support a default value for decimals. The second overload takes only two parameters, not changing the number of decimals at all. Hence, the number of decimals will only be changed if the user explicitly specifies it. To maintain the old behavior of setRange(), pass 0 as the 3rd argument explicitly. Note that it is a source-incompatible change. But it should be fine, because using QDoubleValidator with 0 digits after decimal point does not make much sense and so, hopefully, is not that common. At the same time, change the default-constructed QDoubleValidator to use -1 for decimals, which allows arbitrarily many digits in the fractional part. The value was previously 1000, which allowed more than anyone would reasonably use, so this should make no practical difference. Some more unit tests to cover the behavior of the setRange() overloads are also added. As a dirve-by: remove unnecessary QValidator::State to int conversions in the unit tests. QCOMPARE is capable of comparing these enums and provides a better output in case of failure for enums.

* rhi: vulkan: Reset state more aggressivelyLaszlo Agocs2021-09-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | ...when starting a render/compute pass. This matches most other backends in fact, the Vulkan backend has just certain historical differences, and is complicated due to the fact that it has the option of using secondary command buffers for passes that specify ExternalContents (to support the case of wanting to issue direct Vulkan commands in a code block surrounded by calls to beginExternal and endExternal). Not resetting state such as the currently bound index buffer when starting a pass quickly blows up when two consecutive render passes use different settings, one targeting the primary while the other the secondary command buffer. Instead of further complicating the logic, just reset the relevant state in every begin(Compute)Pass. Comes with an autotest that is crafted so that it manages to downright crash when run with Vulkan without the fix to the backend.

* Fix querying font aliases that share name with other fontsEskil Abrahamsen Blomfeldt2021-09-111-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a332f3fabc29f796526202648eddf35a24f1cb67 disabled resolving all fonts on the system for every font lookup, which was a significant startup time improvement. But it also caused a regression: When a font has an alias which shares the name of a proper font, then this would not be resolved correctly. This is fairly typical on Windows/GDI due to backwards-compatibility. Instead of being collected under a shared typographical family, fonts are disambiguated by adding the style name to the family name. The proper typographical name is still available, but this is not enumerated by the system. So "Segoe UI" for instance, will be available as "Segoe UI", "Segoe UI Light", "Segoe UI Bold" etc. When we populate family aliases, we register that "Segoe UI Light" is actually "Segoe UI" with Light weight, and prior to a332f3fabc29f796526202648eddf35a24f1cb67 this would be done implicitly. But after the optimization, we would only populate family aliases once we stumbled over a font request for a non-existent font. For "Segoe UI", we would simply return the regular weight font as the best imperfect match. The fix is to populate font family aliases not only when the family is non-existent, but when the match is imperfect, e.g. if we are asking for a Light weight font and only finding a regular one. User code can still avoid this somewhat expensive operation by using the full family names on Windows. This also requires a fix to a test. When removeApplicationFont() is called, we invalidate the font database, so it will be reset to a state that does not contain the family aliases. Therefore we cannot guarantee that it is identical to what it was before the test started, since this depends on what has happened previously in the application. [ChangeLog][QtGui][Text] Fixed an issue where some font styles and weights would not be selectable. This was especially noticeable on Windows.

Not relevant for the OpenGL backend, while D3D and Metal may get away without doing this, but the Vulkan backend gives visible rendering errors in Qt Quick once updateResources() is taken into use and a scene manages to do the "right" amount and types of changes. The most common source is a changing uniform buffer offset. Consider how the Qt Quick scenegraph merges uniform data into a single buffer in unmerged batches (i.e. when a set of geometry nodes cannot be batched together in a single draw all). While each node gets its own draw call, each associated srb refers to the same uniform buffer at binding point 0, just with a different offset. Without the layout-compatible-update optimization (that is QRhiShaderResourceBindings::updateResources()) this is not something that needs extra care: once an srb is built or rebuilt (by calling create()), the offset, just like the resource itself is fixed and cannot change. And once create() is called, it conveniently invalidates all related data structures, leading to the subsequent setShaderResources() rewrite descriptors (incl. the resource, the offset, etc.) with Vulkan or do whatever is relevant with other backends. updateResources() only does the minimum amount of changes because we know that the binding list layout has not changed. It turns out this was a bit too minimal, because certain state tracking data structures still need resetting, just as if we called create(). The problem is becoming apparent with non-layout data such as the uniform buffer offset, storage buffer offset, or the storage image mip level. It however works as expected when changing the resource itself. E.g. if a binding point now references a QRhiBuffer different than before, then there is no visible problems, regardless of the buffer offset being different or the same. Hence being difficult to discover, until the aforementioned Qt Quick renderer case triggers it. Why is this? Changing the resource (buffer, texture, sampler) itself works due to the guarantees given by the QRhi resource model. Consider the following: ubuf is a uniform buffer ubuf->create(); srb->setBindings({ references ubuf }); srb->create(); // use the srb in some draw calls // ... // later, when preparing the next frame we decide we need new data with // a different size even: ubuf->setSize(new_size) ubuf->create(); // fill in new data to ubuf // use the srb in some draw calls at this point "magic" happens: note how there is no rebuilding of the srb itself (no create(), no nothing), yet it will correctly pick up the now-different native buffer objects underneath ubuf. This works because there is a certain degree of state tracking happening that allows recognizing that a resource referenced from an srb got rebuilt and now has different native objects (e.g. a VkBuffer) underneath, which in turn needs (with Vulkan) rewriting the associated descriptor with the new native resource. Incidentally, this also makes updateResources() work just fine as long as it replaces the QRhiBuffer/Texture/Sampler reference for the binding point. However, with the example snippet above there is no way to change the other associated data such as the buffer offset. (that would need rebuilding the srb with create(), and that resets all related state tracking structures) So once we encounter an updateResources() where the same QRhiBuffer is now used with an offset different from before, that is not recognized by setShaderResources() and (with Vulkan) it will not rewrite the descriptor with the new offset. (unless the changes for another resource in the binding list trigger it; the granularity here is quite coarse, i.e. we either rewrite (with Vulkan) all descriptors or none at all; this makes the problem even less apparent because now rendering errors occur only when Qt Quick ends with an update where only the uniform buffer offset, but nothing else changed) Pick-to: 6.2 Change-Id: I82ee43aa358947288135ff72ec213e091342e9cb Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* rhi: Make the serialized srb layout description accessibleLaszlo Agocs2021-09-072-1/+14
| | | | | | | | | | | | | | | | | | | | | ...by the Qt Quick renderer, for example. A typical Qt Quick material binding set serializes to 8 uints. This would not demand a container like QVector. However, being implicitly shared is essential here due to the intended usage (query the serialized blob, put it into a cache key, hash it, compare it, all without any copying and new allocs; we can afford an extra alloc upon each srb construction, but don't want more afterwards in the rendering engines) Also make it clear in the pipeline docs that the optimization Qt Quick is (soon going to be) doing is legal. (the srb ref in the pipeline can be dead and dangling as long as every call to setShaderResources() specifies a layout-compatible alternative) Pick-to: 6.2 Change-Id: I97efbea1fa3516b10c9832adbab0a21b7bc0845d Reviewed-by: Andy Nichols <andy.nichols@qt.io>

| | | | | | | | | | | | On OpenSUSE we seem to get an Enter event after or while the QWindow is closed, and that appears to reset the currentMouseWindow after we cleared it in QWindowPrivate::destroy.

* rhi: Add a way to tell an srb that only the resources have changedLaszlo Agocs2021-09-0311-0/+70
| | | | | | | | | | | | | | | | | Until now, after updating the bindings one had to always rebuild the srb, which can be heavy esp. on Vulkan (release old objects, create new layout object, descriptor sets). When updating the binding list in a way that it is fully isLayoutCompatible() == true with the previous list, this is an overkill. Internally, most notably in setShaderResources(), we already should have everything in place in all backends to recognize if the entries in the binding list refer to QRhiBuffer/Texture/Sampler objects that are different than before, and so apart from adding an alternative to create() in the API there is not much else needed here.

| | | | | | | | | | | | | | | Relevant for Vulkan, given that descriptorCount is part of VkDescriptorSetLayoutBinding, meaning two srbs with arrays of SampledTextures should only be reported as compatible if the array size matches. Also reduces the prealloc size for the VLAs. For Qt Quick even a lower number would be sufficient, but we still keep the number something fairly high in order to play nice with Quick3D.

* QWidget: close the QWindow in QWidget::closeVolker Hilsheimer2021-09-022-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | We want to close the window, end full screen mode on macOS, and free platform resources. This is all done by QWindow::close. QWindow::close closes the platform window, triggering a closeEvent to QWidgetWindow, which then calls QWidgetPrivate::close_helper. This way, closing a window via QWidget::close, QWindow::close, or interactively by the user are all equivalent. The QCloseEvent generated by the widget needs to be spontaneous for window-system generated events (i.e. the user clicked the close button), and non-spontaneous if the window closes because of a call to QWindow::close. To keep track of whether the event originated in an explicit call to QWindow::close, add a boolean to the QWindowPrivate. Add a test case that verifies that the window resources is destroyed, and that events are delivered as they should.
