Eskil Abrahamsen Blomfeldt 43a63901f4 Fix bug with NoFontMerging when font does not support script
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.

[ChangeLog][QtGui][Text] Fixed an issue with NoFontMerging and
changing font families dynamically, where boxes would be seen in
place of the correct text.

Laszlo Agocs 213755a866 rhi: metal: Make base vertex and instance support optional
Like we do for OpenGL. Conveniently enough the QRhi feature flags are

This should prevent errors such as:

MTLValidateFeatureSupport:3901: failed assertion `Base Vertex Instance

on the iOS Simulator. It is not clear since which version or SDK this
became a fatal problem, but the base vertex/instance support is indeed
an optional feature according to the Metal Feature set tables, so not
calling the drawIndexedPrimitives variant taking baseVertex and
baseInstance when the reported iOS GPU family is too low is the right
thing to do regardless.

Tor Arne Vestbø 853c350cca macOS: Map dead keys directly to their terminator when building key map
When a key press comes in we may end up in QAppleKeyMapper::possibleKeys()
as part of checking whether the key press should trigger a QShortcut.
The function builds on QAppleKeyMapper::keyMapForKey(), which provides
a map from the given virtual key to all the possible Qt::Keys that can
be produced by applying different modifier key combinations.

The map is built using the Carbon function UCKeyTranslate, that takes
the current keyboard layout, virtual key, and modifiers, and produces
the resulting characters. The function also maintains a running dead
key state via one of the arguments. When mapping a dead key, the state
variable will be updated to the current dead key state, which then
affects the next call to the function (for the next key press).

The problem is that we're not calling UCKeyTranslate for each key press.
We are calling it in a loop, for a single key press, to build up a map
of all the possible characters produced by varying the modifier keys.
And in doing so, we are passing on the dead key state from one call
to the next, even if these are for different modifiers. The result is
that the first call, for the dead key, results in mapping to \0, as
UCKeyTranslate produces no output, it only modifies the dead key state.
And then the next call, for the next modifier key combination, results
in mapping to a character that incorrectly incorporates the dead key
state (resetting it in the process).

What we really want is to directly map the initial modifier combination
to the dead key terminator character, if one is defined. This is the
character produced if the dead key state is cancelled, for example by
pressing a key that's not defined in the dead key state.

To achieve this we pass kUCKeyTranslateNoDeadKeysMask as the translate
options to UCKeyTranslate, and always reset the dead key state before
every call. Another common way to achieve the same result would be to
call UCKeyTranslate a second time when detecting that the first call
produced a dead key state, for example with a synthetic space key, to
trigger the terminator output. But this can potentially fail if the
space key actually has a defined output in the dead key state.

Tor Arne Vestbø 99a4419647 macOS: Don't treat null-key as potential shortcut key
When mapping virtual keys and modifiers to their corresponding characters
via a keyboard layout we may hit combinations that do not produce any
characters. This can happen if there's no <key> element defined for the
virtual key, or if the output attribute of the element is empty (despite
the spec saying there should always be one UTF-16 code point in the output).

 https://developer.apple.com/library/archive/technotes/tn2056/_index.html

When that happens QAppleKeyMapper::keyMapForKey() will map the combination
to a null-QChar, resulting in the "key" being 0. We do not want to propagate
this back to the QShortcutMap machinery, as QShortcutMap does not validate
the keys coming out of QKeyMapper::possibleKeys(). In particular, it doesn't
check the isEmpty() or count() of the QKeySequences it creates. And even if
it did, QKeySequence itself seems to treat Qt::Key(0) + Qt::SomeModifier
as a non-empty sequence, so passing on 0-keys would still give weird bugs.

The user-visible result of passing back 0-keys is that QShortcutMap will
treat it as a partial match for any incoming key combination (as long as
some modifier is pressed that triggers the QShortcutMap machinery), which
resulting in eating the key press. This compounded the issue in QTBUG-95471.

Regression after fab3dfff7d.

Resize QPlatformWindow on DPI change, so that QWindow
size can stay approximately constant.

For example, a 100x100 QWindow at 100% scaling will
have a 100x100 QPlatformWindow. If the scaling is changed
to 200% then the QPlatformWindow is resized to 200x200,
while the size of the QWindow stays at at 100x100.

In practice the QWindow size will also change slightly,
due to inaccuracies in how we adjust for the size of the
non-client window area. This will be addressed in a later commit.

We can get DPI change independently of screen change,
so no resizing should happen in screen change events.
Disable the resize code in QGuiApplication for Q_OS_WIN,
and remove the WithinDpiChanged flag.

The new flow for handling DPI change is:

  1) Send screen change (if any), so that the correct
     screen will be used when calculating scale factors
     during the following resize.
  2) Resize the native window, which will trigger geometry
     change events, possibly also for the QWindow.
  3) Resize child windows; WM_DPICHANGED is sent to
     top-level windows only.

Marc Mutz 73fabadcee QXpmHandler: fix re-entrancy bug in xpm_color_name
The xpm_color_name() function returned a pointer to a function-static
buffer. This is infamously non-reentrant, and an actual problem,
because we explicitly allow QImage operations (incl. saving to an
.xpm) from non-GUI-threads.

Fix by using the CSS pattern (Caller-Supplied Storage; also used in
the QAnyStringView(char32_t) and QAnyStringView(QStringBuilder) ctors)
to force the caller to allocate storage in its own stack frame. As a
consequence, we re-gain re-entrancy, but the returned pointer is now
only valid until the end of the full-expression, which necessitated
simplifying one caller (sorry!).

To see why said simplification is valid, observe that xpm_color_name()
writes a (now-explicit) NUL into returnable[cpp] and the old code read
max(cpp, 4) characters from xpm_color_name()'s result.

NB: cpp can be 5, even though the code comments say otherwise! :(

One is a bad application or library in this case, but nonetheless
we should handle this more gracefully then just crashing due to

could get away with the same: releasing OpenGL objects underneath,
for example, a QSGPlainTexture with no (or wrong) GL context did
not generate any user visible fatal errors. So we should not crash
in Qt 6 either with these code bases.

In debug builds or when QT_RHI_LEAK_CHECK is set, one will get the
unreleased resources warning printed in Qt 6, which is a step
forward compared to Qt 5. So there is still some indication that
something is badly designed, even if the application survives.

So over time, QInputDevice::devices() should build up to a complete

Alexandru Croitor 3c23317552 CMake: Make WrapVulkanHeaders target optional for QtGui consumers
If Vulkan headers are present on the system when qtbase is configured,
QtGui and QtOpenGL should be compiled with Vulkan support.

If a user project uses a Qt built with Vulkan support, but their system
is missing Vulkan headers, the project configuration needs to succeed.

The project will get compilation errors if it uses Vulkan headers, but
that's intended.

This use case was broken when fixing Vulkan to be found when building
Qt for Android.

Fix the regression with a combination of things
1) Mark the WrapVulkanHeaders package as optional (already the case)
2) Use the include directories directly when compiling Gui and OpenGL
3) Propagate WrapVulkanHeaders::WrapVulkanHeaders link requirement to
   consumers only if the target exists. It won't exist if Vulkan
   include dirs are not found

This also requires some changes in pri and prl file generation.

For prl file generation, we don't want to link to the
WrapVulkanHeaders target, so we filter out all dependencies that
use TARGET_NAME_IF_EXISTS for anything that calls
__qt_internal_walk_libs which includes qt_collect_libs.

For pri files, we make sure to generate a uses=vulkan/nolink clause
by inspecting a new _qt_is_nolink_target property on the target.

We also don't add include dirs to the pri file if the new
_qt_skip_include_dir_for_pri property is set.
This is intended for Vulkan, because there is separate qmake logic to
try and find the include dirs when configuring a user project.

As a drive-by, fix nolink handling for WrapOpenSSLHeaders.

Marc Mutz 25fff849e8 QDirIterator: add nextFileInfo()
Before this change, next() was the only way to advance the iterator,
whether the caller was ultimately interested in just the filePath()
(good) or not (bad luck, had to call .fileInfo()).

Add a new function, nextFileInfo(), with returns fileInfo() instead.
Incidentally, the returned object has already been constructed as part
of advance()ing the iterator, so the new function is faster than
next() even if the result is ignored, because we're not calculating a
QString result the caller may not be interested in.

Use the new function around the code.

Fix a couple of cases of next(); fileInfo().filePath() (just use
next()'s return value) as a drive-by.

[ChangeLog][QtCore][QDirIterator] Added nextFileInfo(), which is like
next(), but returns fileInfo() instead of filePath().

Giuseppe D'Angelo 08411a3ddf QTextCharFormat: mark a couple of API mistakes to be fixed in Qt 7
The fontFamilies and fontStyleName have an asymmetric getter and setter.
The setter takes QStringList, but the getter returns QVariant (?), for
no reason whatsoever (the underlying QFont APIs take QStringList,
and the docs say that they should return QStringList).

It's not entirely obvious that we can fix this without introducing
badly-named getters (getX) or somesuch, so for the time being, mark
this to be fixed in Qt 7.

Volker Hilsheimer a1a6e3d21b Support pt units for sizes, as documented
Declaration::lengthValue only supported 'px' sizes, but one can transform
any 'pt' value into 'px' by multiplying with 1.33.

Notes: this ignores display DPI, and instead follows the W3C definition
of 'pt' and 'px' as absolute lengths [1].

[1] https://www.w3.org/TR/css3-values/#absolute-lengths

1pt = 1/72th of 1 inch
1px = 1/96th of 1 inch

so the conversion is px = pt * (72/96).

Add unit test that verifies this using QPushButton's icon-sizes property,
also with changed font in preparation of adding support for 'em' and 'ex'
units in a follow up commit.

By switching out the static_assert for an enable_if we end up producing
a clearer error, at the call site:

/qt/qtbase/examples/gui/rasterwindow/main.cpp:69:9: error: no matching member
      function for call to 'nativeInterface'
    app.nativeInterface<QNativeInterface::QCocoaGLContext>();

      QNativeInterface::Private::NativeInterface<QNativeInterface::QCocoaGLContext>, BaseType =
      QGuiApplication]
    QT_DECLARE_NATIVE_INTERFACE_ACCESSOR(QGuiApplication)
    ^
By using SFINAE for the TypeInfo we can also ensure that it works for
types that are not native interfaces, such as if the user tries to
call nativeInterface<QString>().

Since we can no longer use decltype(*this) to resolve the base type
we need to change QT_DECLARE_NATIVE_INTERFACE_ACCESSOR to take the
type as an argument, as we do for other QT_DECLARE_FOO macros.
