Using convertDoubleTo() to get a whole number, from which to determine
the number of digits we're allowed before the fractional part, fails
if the double isn't a whole number, which lead to the skip being
checked. Use qFloor() of the double (as this should have as many
digits as the double had before its decimal point, which is what we
care about; qCeil() might round up to a power of ten).

...by removing the entire adjustedFormat() helper.
Qt Quick has never used this, which indicates it is not that
useful. Same goes for Qt Multimedia or Qt 3D. Ensuring depth and
stencil is requested is already solved by using
QSurfaceFormat::setDefaultFormat() or by adjusting the formats
everywhere as appropriate.
The helper function's usages are in the manual tests that use it as a
shortcut, and in the GL backend itself. Remove it and leave it up the
client to set the depth or stencil buffer size, typically in the
global default surface format. (which in fact many of the mentioned
manual tests already did, so some of calls to
window->setFormat(adjustedFormat()) were completely unnecessary)
By not having the built-in magic that tries to always force depth and
stencil, we avoid problems that arise then the helper cannot be easily
invoked (thinking of widgets and backingstores), and so one ends up
with unexpected stencil (or depth) in the context (where the GL
backend auto-adjusts), but not in the window (which is not under
QRhi's control).
It was in practice possible to trigger EGL_BAD_MATCH failures with the
new rhi-based widget composition on EGL-based systems. For example, if
an application with a QOpenGLWidget did not set both depth and stencil
(but only one, or none), it ended up failing due to the context -
surface EGLConfig mismatches. On other platforms this matters less due
to less strict config/pixelformat management.

Some of the offsets are already quint32 in the API (vertex input
attributes, dynamic offsets, offsets in draw calls), matching the
reality of the underlying 3D APIs, but many buffer-related functions
use int as of now, simply because that used to be the default choice,
and the same goes for sizes (such as buffer or range sizes). This is
not quite consistent and should be cleaned up if for nothing else then
just to make the classes consistent, but also because no 3D API use a
signed type for offsets, sizes, and strides. (except OpenGL for some)
When it comes to strides (for vertex inputs and raw image texture
uploads), those are already all quint32s. This is straightforward
because most of the 3D APIs use 32-bit uints for these regardless of
the architecture.
Sizes and offsets are often architecture-dependent (Vulkan, Metal),
but there is at least one API where they are always 32-bit even on
64-bit Windows (UINT == unsigned int, D3D11). In addition, we do not
really care about buffer or texture data larger than 4 GB, at least
not without realistic use cases and real world testing, which are
quite unlikely to materialize for now (esp. since we still have the
width/height of 2D textures limited to 16 or 32K in many cases even on
desktops, whereas 2GB+ buffers are not guaranteed in practice even
when an API seemingly allows it).
In any case, the important change here is the signed->unsigned
switch. A number of casts can now be removed here and there in the
backends, because the offsets and sizes are now unsigned as well,
matching the underlying API reality. The size can be potentially
increased later on with minimal effort, if that becomes necessary for
some reason.

QFileSystemModel. QAbstractItemModelTester called fetchMore()
on all items. QFileSystemModel represents the whole file system.
This led to very long test runs. To avoid this, this patch
introduces a new feature in QAbstractItemModelTester, namely
to disable calling of fetchMore().

swapchain->currentFrameRenderTarget()->renderPassDescriptor() is not
functional at the moment, it returns null. This is because no backend
ensures that the internal renderpass descriptor object is exposed via
that getter in a QRhiSwapChainRenderTarget. Whereas in a
QRhiTextureRenderTarget this would work by design because there the
setter must be called by the user.
Fix this up, providing better API symmetry, and also reducing the need
to pass along QRhiRenderPassDescriptor objects seprately alongside a
QRhiRenderTarget in some places, e.g. in Qt Quick.

There's no advantage to them being inline: Absent de-virtualisation,
clone() is only supposed to be called through the vtable, and the copy
ctor is only supposed to be used in the implementation of clone().
And when the compiler de-virtualises, we don't want the code
duplication associated with inlining.
Enforce this by introducing new macros to hide the boilerplate.
This fixes missing out-of-line dtors in:
- QSinglePointEvent
- QApplicationStateChangeEvent
- QFutureCallOutEvent
Wrong covariant return in:
- QFutureCallOutEvent
And missing clone() reimplementations in:
- QCloseEvent
- QIconDragEvent
- QShowEvent
- QHideEvent
- QDragEnterEvent
- QDragLeaveEvent
While these don't carry extra data or members, a dynamic_cast of the
result of clone() as well as using the expected covariant return value
would fail:
QShowEvent *e = ~~~;
QShowEvent *e2 = e->clone(); // ERROR: converting QEvent* to QShowEvent*
Check that reimplementing clone() is binary compatible (covariant
returns may change the numerical pointer value returned, cf.
https://community.kde.org/Policies/Binary_Compatibility_Issues_With_C%2B%2B).
The copy-assignment operator stays inline for the time being, as the
goal is to = delete it in the future.

We want to enable gaining access to the underlying resource(s) by
inspecting a QRhiRenderTarget. This is not currently possible for
swapchains since there is nothing that references the actual
QRhiSwapChain. To clean this up, make an explicit, new
QRhiSwapChainRenderTarget subclass. Thus the logic already used in a
couple of places to examine the resources attached to a
QRhiTextureRenderTarget can now work with swapchain render targets too,
by branching based on the resourceType().
This eliminates the somewhat odd setup where a "RenderTarget" resource
is QRhiRenderTarget corresponding (but not exposing!) a swapchain,
whereas a "TextureRenderTarget" is a QRhiTextureRenderTarget which
is a subclass of QRhiRenderTarget. Now we correctly have an (abstract)
base and two subclasses, one for each type of render targets.
Besides, it allows us to clean up the oddly named
Q...ReferenceRenderTarget classes in the backends, which initially tried
to indicate that this "render target" merely references (or, in
practice, is) a swapchain. We can now have a nice and symmetrical
Q...SwapChainRenderTarget and Q...TextureRenderTarget naming scheme.

In QPainter, clipping can only be done on whole pixels. The various
ways of specifying a clipping rectangle to the QPainter API have been
inconsistent in how fractional rectangles (either specified directly,
or as a result of fractional scaling) are mapped (rounded) to integer
coordinates.
Also, the mappings have not made sure to keep the edge-to-edge
property of clip rects under scaling. This is particularly important
when scaling QRegions with multiple rects, as QRegion is designed on
the assumption that an area can be described as a set of edge-to-edge
rects.
The fix rounds a clip rect identically with a fill rect. (Indeed, a
followup plan would be to merge QRasterPaintEngine's
toNormalizedFillRect() with the rectangle rounding function in this
commit).
Notably, a QRectF clip is now interpreted the same as a QPainterPath
clip describing the same area.

Calling QGuiApplication::setLayoutDirection(Auto) has so far been a
no-op.
Change this logic so that the stored layout direction continues to be
LayoutDirectionAuto also if it's set based on auto-detection, and only
overwrite it when explicitly called with a non-Auto value. This way,
applications can set a layout direction that stays unchanged even when
translators are installed.
Add test coverage that uses a QTranslator.
In practice, this is not a change of behavior, unless applications called
setLayoutDirection(Auto) (which is no longer a no-op), or called
setLayoutDirection() and then installed a translator and expected the
translator's layout direction to come into effect in spite of the explicit
setting.
[ChangeLog][Gui][QGuiApplication] Calling setLayoutDirection with a non-

There is a TODO for this in Qt Quick from the 6.0 times. To decide
upfront if Metal can be expected to function, or if a fallback to
OpenGL needs to be triggered (especially important with macOS virtual
machines, where, unlike any real macOS system, Metal may not be
present at all), the scenegraph calls create() and then drops the
result. The idea to make this less wasteful was back then to add a
dedicated probing function which can, possibly, perform the checks in
a more lightweight manner than full initialization. Implement this
now, focusing on Metal.
Brought to attention by QTBUG-100441: printing warnings about not
having an MTLDevice is confusing in a Metal-less macOS VM, because it
is not an actual error, only part of the probing at scenegraph
initialization. We can now avoid printing confusing warnings there.

In order to work around the precision problem, this patch does:
1. switch to the algorithm described in the inline comment to make
the story simple.
2. forcibly normalize the {x, y, z, w} components to eliminate
fractional errors.
3. set threshold to avoid hidden division by cos(pitch) =~ 0.
From my testing which compares dot product of the original quaternion

In Qt 5 style sheets, objects could be selected by an enum-type property
using the integer value of the enum value, e.g
QToolButton[popupMode="1"] { ... }
In Qt 6, the the new meta type system and QVariant implementation enabled
QVariant::toString to return the string representation of the enum value
instead for a property containing an enum. Since QStyleSheetStyle's
attribute matching is string based, this breaks the Qt 5 style selector,
and QCSS code instead needs to use e.g.
QToolButton[popupMode=MenuButtonPopup] { ... }
While the new syntax is arguably preferable, this is an unintentional
change that silently breaks style sheet code (no error or warning at
compile- or run-time).
To support Qt 5-style selectors, we have to change the StyleSelector
interface of the QCssParser API so that we can pass through what type
of value the attribute extractor should return; if an integer string "1"
is provided, then we need to compare the enum integer value; if the
string provided does not represent a number, then we need to compare the
name of the enum value.
Since the pure virtual attribute() method that needs to be implemented
to extract the attribute value of the node is implemented in modules
outside qtbase, add a second virtual method that takes the entire
QCss::AttributeSelector, which includes the value to match. Extractor
implementations can use it to evaluate which type of data to return for
an exact match. The default implementation calls the old attribute()
method so that existing StyleSelector implementations continue to work.
Make the respective change in the QStyleSheetStyleSelector, and simplify
the surrounding code. Adjust other StyleSelector implemnentations in
qtbase. As a drive-by, remove the superfluous virtual declaration from
those overrides.
Once submodules are adjusted to override this virtual function instead
of the (now no longer pure) virtual attribute() method, that method can
be removed.

For Direct 3D, Metal, and Vulkan this is natively supported. (and
makes no difference in particular for D3D and Metal because they do
not have the legacy combined image sampler concept anyways)
With OpenGL it will work too, but this relies on SPIR-Cross magic and
is still using a combined sampler (e.g. a sampler2D) in the GLSL
shader. The GL backend walks back and forth in the mapping tables from
the shader baker in order to make this work, which is presumably
slightly more expensive than combined image samplers.
Do note that combined image samplers (i.e. sampler2D in the shader and
QRhiShaderResourceBinding::sampledTexture() in code) continue to be
the primary, recommended way for any user of the rhi for the time

QWidget and QWindow use bits in QObjectPrivate to provide for a couple
of shortcuts -- one in qobject_cast, and another in the isWidgetType() /
isWindowType() functions in QObject. These can be optimized by simply
looking at the bits, without actually doing more expensive runtime
casts.
These bits were set on construction, but not unset on destruction. The
result was for instance that destroying a QWidget would report that the
object was still a QWidget when ~QObject was reached.
Fix this
1) by setting the bits only when QWidget / QWindow constructors start;
2) by resetting the bits once ~QWidget / ~QWindow are completed.
Technically speaking this is not 100% correct in the presence of data
members, but luckily those classes don't have any.

destruction (after QWidget's (resp. QWindow's) destructors had been

The system we inherited from the original Qt 5.14 introduction of QRhi
is a text stream based solution where resource creation and frame
timings are sent in a comma-separated format to a QIODevice.
This, while useful to get insights about the number of resources at a
given time, is not actively helpful. The frameworks built on top (Qt
Quick, Qt Quick 3D) are expected to provide solutions for logging
timings in a different way (e.g. via the QML Profiler). Similarly,
tracking active resources and generating statistics from that is
better handled on a higher level.
The unique bits, such as the Vulkan memory allocator statistics and
the GPU frame timestamps, are converted into APIs in QRhi. This way a
user of QRhi can query it at any time and do whatever it sees fit with
the data.
When it comes to the GPU timestamps, that has a somewhat limited value
due to the heavy asynchronousness, hence the callback based
API. Nonetheless, this is still useful since it is the only means of
reporting some frame timing data (an approx. elapsed milliseconds for
a frame) from the GPU side.

Adds the following in a QShader/QShaderDescription:
- a list of separate images
- a list of separate samplers
- a list of "combined_sampler_uniform_name" -> [
separate_texture_binding, separate_sampler_binding ] mappings
(relevant for GLSL only)
On the QShader (and qsb/QShaderBaker) level not having separate image
(texture) and sampler objects exposed in the reflection info is not
entirely future proof. Right now we benefit strongly from the fact
that Vulkan/SPIR-V supports both combined and separate
images/samplers, while for HLSL and MSL SPIRV-Cross translates
combined image samplers to separate texture and sampler objects, but
it is not given that relying on combined image samplers will always be
possible in the long run; it is mostly a legacy OpenGL thing that just
happens to be supported in Vulkan/SPIR-V due to some benefits with
certain implementations/hw, but is not something present in any newer
APIs.
In addition, before this patch, attempting to run a shader with
separate textures and samplers through qsb will just fail for GLSL,
even though SPIRV-Cross does have the ability to generate a "fake"
combined sampler for each separate texture+sampler combination. Take
this into use. This also involves generating and exposing a
combined_name->[separate_texture_binding,separate_sampler_binding]
mapping table for GLSL, not unlike we have the native binding map for
HLSL and MSL. A user (such as, the GL backend of QRhi) would then use
this table to recognize what user-provided texture+sampler binding
point numbers correspond to which auto-generated sampler2Ds in the GL
program.
Take the following example:
layout(binding = 1) uniform texture2D sepTex;
layout(binding = 2) uniform sampler sepSampler;
layout(binding = 3) uniform sampler sepSampler2;
Inn the reflection info (QShaderDescription) this (assuming a
corresponding qtshadertools patch in place) now gives one entry in
separateImages() and two in separateSamplers(). Assuming sepTex is
used both with sepSampler and sepSampler2, the GLSL output and mapping
table from QShaderBaker will have two auto-generated sampler2Ds (and
no 'texture2D' or 'sampler').
One immediate benefit is that it is now possible to create a shader
that relies only on separate images and samplers, feed it into qsb,
generate all the possible targets, and then also feed the SPIR-V
binary into a tool or library such as Tint (e.g. to generate WGSL)
that canot deal with combined image samplers.

After 556511f9f3, which moved the resolve
mask storage into the palette's d-pointer, modifying the resolve mask
requires a detach. As of now, we only detached when setting a different
brush, but always modified the resolve mask, which broke palettes that
shared the d-pointer (likely the global default palette).
However, detaching has negative side effects when styles set brushes on
temporary palette objects and then use that palette object's cache key
to build a cache of pixmaps. As each drawing would detach the palette
(even if the palette doesn't change, which is likely), the cache key
changes with each detach, and the cache would quickly increase in size.
This was addressed in changes d7bcdc3a44

We can either detach and find other ways to address the issues from

Since QFont ignores the setting of any attribute to a value that is

the resolve-bit is set by calling setBrush twice with different brushes,
ignoring the call seems like the better solution.

In Qt 5, fonts had both singular family and plural families properties,
and both were stored separately when streaming through QDataStream. The

the primary font family was always the singular family property.
In Qt 6, it has been merged into one and family() is now just a

But when reading files generated with Qt 5, we would ignore the fact
that these were previously separated. We would first read the family
entry into the families list, and then we would later overwrite this
with an empty families list.
Instead, we detect streams created with Qt 5.15 or lower and make sure

Arrays of textures have always been supported, but we will encounter
cases when we need to work with texture array objects as well.
Note that currently it is not possible to expose only a slice of the
array to the shader, because there is no dedicated API in the SRB,
and thus the same SRV/UAV (or equivalent) is used always, capturing
all elements in the array. Therefore in the shader the last component
of P in texture() is in range 0..array_size-1.

In a text line that has a change of direction at either end of the text,
the cursor needs to be positioned where the next character is inserted,
or where backspace deletes the previous character. In bidi text, this is
ambiguous as illustrated by this example:
abcشزذ
Depending on whether this string was typed in a left-to-right document
or in a right-to-left document, it could be first latin, then arabic; or
it could be first arabic, then latin.
If a general left-to-right context, cursor position 0 should be in front
of the 'a', and cursor position 6 should be at the end of the arabic
text, in the visual middle of the line. Cursor position 3 can be either
after the 'c' if the next character typed would be latin, or at the
visual end of the line if the next character will be arabic.
Qt calculated the cursor position past the right end of the text as 3
(which is not wrong, but 3 has two visual positions), and placed the
cursor at the visual end of the line (favoring the right-to-left
alternative). Backspace would then delete the 'c', writing a new
latin character would insert a 'd' next to the 'c', writing a new arabic
character would insert it also in the middle - none of these operations
happen at the visual end of the line, where the cursor was blinking.
To fix this, we take into account the general layout of the text, which
is typically based on the document, or the user's locale setting and UI
translation, and calculate the cursor position accordingly: if we are
past the visual end of the document on either side, then the cursor
position is either 0 or the last character of the text, depending on the
direction of the QTextEngine used. This way, the cursor ends up in the
middle of the document when we click beyond the end of the line, which
is where characters are removed and inserted. Typing a 'd' at this point
will make the cursor jump to the end, where the d is added.
There are still corner cases: clicking on the right-most arabic character
calculates the cursor position as 3, which is then ambiguous, as it can
be either at the visual end of the string, or next to the 'c'. َQt makes
the inconsistent choice to place the cursor at the visual end, showing
the left-to-right indicator, but pressing a 'd' adds the 'd' after the
'c' in the middle of the text.

When parsing CSS, a border-color value is parsed as four brushes, as css
allows assigning up to four values, one for each side.
When applying the CSS to the HTML, we accessed it as a color value,
which overwrote the parsed value with a QColor. So while we had a valid
parsed value (and didn't re-parse), the code accessing that value still
expected it to be a list, and thus failed to retrieve the data.
There are several ways to fix that, but the cleanest way without
introducing any performance penalty from repeatedly parsing (and in fact
removing a parse of the string into a color) is to enable colorValue to
interpret an already parsed value that is a list without overwriting the
parsed value again. To avoid similar issues in the future, add assert
that the parsed value has the right type in brushValues.
As a drive-by, speed things up further by making use of qMetaTypeId
being constexpr, which allows for it to be used in a switch statement.

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.

a332f3fabc 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
a332f3fabc 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.

When using NoFontMerging, no fallbacks should be resolved. If the
font does not support a specific character in the text, we should
display a box instead of merging it with another font.
But in practice, Qt would still apply the fallback mechanism for
one specific case: If the font itself does not support the script
of the text, we would get no match and do a search for a fallback
instead. Since NoFontMerging is set, we would then force this
as preresolved for *all* scripts in the QFont's private data
(logically, the match should only have a single response for
NoFontMerging).
The end result was that if you set the font family before updating
the text, you would get broken rendering. This can happen e.g. in
Qt Quick, where you could update the font family of a text label
while it contains characters which are not supported by the new
font. Qt would then pick a fallback instead. When you subsequently
update the text, the fallback would already be preresolved for
whatever script this is. If it does not support the updated text,
we would then see boxes, even if the requested font actually would
have supported it.
The fix is simply to do an additional pass if NoFontMerging is set
and we were not able to match with the specified script. Since
the same family might be available in different foundries, with
different writing system support, we still want to do a pass first
to see if we can match the exact script of the text.
Note that QRawFont::fromFont() exploited the bug by using
NoFontMerging for getting the fallback font for a specific
writing system. To keep this working without having to rewrite
fromFont() and risk introducing regressions, we add an argument
to make the findFont() function behave as before. It isn't
super-pretty, but since it is private API it is hopefully fine.

The QWARN() macro and corresponding internal QTest::qWarn() function

This theory is backed by our own QtTest self-test (tst_silent)
describing the output from QWARN() as "an internal testlib warning".
The only difference between QWARN() and qWarning(), besides the much
richer feature set of the latter, is that qWarning() will not pass

make_shared or QSharedPointer::create() should be used to reduce
number of memory allocations.
Since this is private API, we're free to use std::shared_ptr, which
does only half the atomic operations on copies, compared to
QSharedPointer, so is more efficient.
For either make_shared or QSharedPointer::create(), we need to work
around the private ctor, which we do by inheriting a member-function
local class from QColorTrcLut and make_shared'ing that. As a
member-function-local class, it has access to the otherwise private
parts of QColorTrcLut, including its default constructor. As a public
subclass, shared_ptr has no problem performing the derived-to-base
pointer adjustment in the return statement. This way, we can use
make_shared even though our target's class' ctor is private.
