Unlike the 32-bit version, we can't go to a bigger integer type to do
the multiplication with. So instead accept looping. Both libstdc++ and
libc++ implement std::uniform_int_distribution this way anyway, but in a
far more complex way.
There is no looping if the "highest" is a power of two. The worst-case
scenario is when "highest" is one past a power of two (like 65). In that
case, we'll loop until the number is in range. Since all bits have equal
probability of being zero or one, there's a 50-50 chance that the most
significant useful bit will be set[*], in which case we'll need to loop
and we again get the same probability. So on average, we only need two
iterations to get an acceptable result.
[*] There's also a possibility that the other bits are such that the
number is still in range. For 65, we'd need the other 5 bits to be zero
(64 is a valid result), but the probability of that is only 1/2^5 =
3.125%. The bigger "highest" is, the closer we get to zero, so
approximate by saying that never happens and instead calculate that the
most significant useful bit is the controlling one.
[ChangeLog][QtCore][QRandomGenerator] Added 64-bit versions of the
bounded() functions. They are useful in conjunction with Qt 6's 64-bit

This commit restricts operator<<(QDebug lhs, QVariant rhs) to only work
if rhs is actually of type QVariant (instead of any type convertible to
QVariant). This is especially important as
a) we check in QMetaType whether (slightly simplified) QDebug{} <<
std::declval<T>() is valid, and if so, register a function which
simply uses the operator.
b) In QVariant, we ask the metatype system for the contained types
registered debug function and then use it.
If a type now does not have its own operator<< for QDebug, but is
implicitly convertible to QVariant containing itself, this would lead to
an infinite recursion, when trying to use qDebug with that type. The
registered function in a) would just convert the type to QVariant, and
then ask the QVariant to print itself.
Disallowing implicit conversions in qDebug in general was considered
(i.e. adding template<typename T> operator<<(T) = delete in QDebug ),
but discarded as it breaks too much code relying on conversions.

Given that we use fuzzy comparison to determine equality of
end-points, isNull() can be false for a line with displacements less
than sqrt(numeric_limits<qreal>::denorm_min()) between the coordinates
of its end-points (as long as these are not much bigger); squaring
these would give zero, hence a zero length, where using hypot() avoids
the underflow and gives a non-zero length. Having a zero length for a
line with isNull() false would lead to problems in setLength(), which
uses an isNull() pre-test, protecting a call to unitVector().
(It was already possible for a null line to have non-zero length; this
now arises in more cases.)
Restored QLine::setLength() to the form it had before a recent change
to avoid division by zero (which resulted from underflow in computing
the length of a non-null line) but allow for the possibility that the
unit vector it computes as transient may not have length exactly one.
Add tests against {ov,und}erflow problems in QLine. Reworked the test
added during the divide-by-zero fix to make it part of the existing
test.

Change the binding loop test, so that there isn't a fixpoint in the

The documentation of convert promised that “If the cast cannot be

the case so far, because we returned too early if canConvert returned
false.
This commit changes the behavior of the method to reflect its
documentation. The documented behavior seems more useful than the
alternative of not changing the metaType, at least for common use cases

In this fix we have additional "tester" timer to measure remainingTime
of "tested" timer. The "tester" is a singleShot timer with interval of
50, and is started together with "tested" timer. Whenever the "tested"
timer timeouts, it restarts the "tester" timer - this is done desired
number of times (2 by default, like in the original test).
The test itself lies now inside tester's lambda. We fix the tested
range (at least 1, no more than 150). The minimum value could in
theory be greater, but it's enough to test that it's not overdue.
Finally, we wait for expected number of test runs. We give it twice
as much time as is in theory needed.

[ChangeLog][Source-Incompatible Changes] QProcess::setupChildProcess()

[ChangeLog][QtCore][QProcess] Added setChildProcessModifier() function
with which one can provide code to be run in the Unix child process

necessary to derive from QProcess in order to execute actions in the

Another reason is that we can tell whether the std::function carries a

overridden.
The setupChildProcess() virtual function does not need to be marked
final, since no overrider could ever return an inaccessible private
class. This also makes sure the error presented to the user is about the
return type, not about attempting to override a final.

Instead of QCoreApplication::quit() directly calling exit(0), which would
leave QGuiApplication and client code out of the loop, we now send the
Quit event, and let it pass through event delivery, before finally ending
up in QCoreApplication::event(), where we call exit(0).
This has the advantage that QGuiApplication can ensure all windows are
closed before quitting, and if any of those windows ignore the close
event the quit will be aborted. This aligns the behavior of synthetic
quits via QCoreApplication::quit() with spontaneous quits from the
platform via QGuiApplicationPrivate::processApplicationTermination.
Clients who wish to exit the application without any event delivery or
potential user interaction can call the lower level exit() function
directly.
[ChangeLog][QtGui] Application termination via qApp->quit() will now

any user interaction should call QCoreApplication::exit() explicitly.

ensure the correct order for started / finised signals.

C++20 via P1120 is deprecating arithmetic operations between
unrelated enumeration types, and GCC 10 is already complaining.
Hence, these operations might become illegal in C++23 or C++26 at
the latest.
A case of this that affects Qt is in key combinations: a
QKeySequence can be constructed by summing / ORing modifiers and a
key, for instance:
Qt::CTRL + Qt::Key_A
Qt::SHIFT | Qt::CTRL | Qt::Key_G (recommended, see below)
The problem is that the modifiers and the key belong to different
enumerations (and there's 2 enumerations for the modifier, and one
for the key).
To solve this: add a dedicated class to represent a combination of
keys, and operators between those enumerations to build instances
of this class.
I would've simply defined operator|, but again docs and pre-existing
code use operator+ as well, so added both to at least tackle simple
cases (modifier + key).
Multiple modifiers create a problem: operator+ between them yields
int, not the corresponding flags type (because operator+ is not
overloaded for this use case):
Qt::CTRL + Qt::SHIFT + Qt::Key_A
\__________________/ /
int /
\______________/
int
Not only this loses track of the datatypes involved, but it would
also then "add" the key (with NO warnings, now its int + enum, so
it's not mixing enums!) and yielding int again.
I don't want to special-case this; the point of the class is
that int is the wrong datatype. Everything works just fine when
using operator| instead:
Qt::CTRL | Qt::SHIFT | Qt::Key_A
\__________________/ /
Qt::Modifiers /
\______________/
QKeyCombination
So I'm defining operator+ so that the simple cases still work,
but also deprecating it.
Port some code around Qt to the new class. In certain cases,
it's a huge win for clarity. In some others, I've just added
the necessary casts to make it still compile without warnings,
without attempting refactorings.
[ChangeLog][QtCore][QKeyCombination] New class to represent
a combination of a key and zero or more modifiers, to be used
when defining shortcuts or similar.
[ChangeLog][Potentially Source-Incompatible Changes] A keyboard
modifier (such as Qt::CTRL, Qt::AltModifier, etc.) should be
combined with a key (such as Qt::Key_A, Qt::Key_F1, etc.) by using
operator|, not operator+. The result is now an object of type
QKeyCombination, that stores the key and the modifiers.

Views / delegates absolutely *adore* hammering data(). A simple
QListView showing a couple of dozens entries can call data()
a hundred of times on the first show.
Back of the hand calculation,
* 2 times per visible item (sizeHint() + paint()),
* times 9 roles used by the default delegate,
* times 20 visible items
= 360 as a bare minimum, assuming the view doesn't redraw twice
accidentally. Move the mouse over the view, and that'll cause
a full update with certain styles: 360 calls to data() per update.
This has an overhead visible in profilers. The model's data()
has to re-fetch the index from its data structure and extract
the requested field every time.
Also, QVariant is used for the data interexchange,
meaning anything that won't fit in one is also a memory allocation.
This problem will likely be gone in Qt6Variant as that
will store sizeof(void*) * 3, meaning QImage/QPixmap and similar
polymorphic classes will fit in a QVariant now...
So I'm trying to to remove part of that overhead by allowing
views to request all the data they need in one go. For now,
one index a a time.
A view might also store the data returned. The idea is that
the same role on different indexes will _very likely_
return variants of the same type. So a model could move-assign
the data into the variant, avoiding the memory allocation
/deallocation for the variant's private.
This patch:
1) Introduces QModelRoleData as a holder for role+data.
2) Introduces QModelRoleDataSpan as a span over QModelRoleData.
The idea of a span type is twofold. First and foremost, we are
in no position to choose which kind of container a view should
use to store the QModelRoleData objects for a multiData() call;
a span abstracts any contiguous sequence, leaving the view free
to do whatever it wants (statically allocate, use a vector, etc.).
It also solves the problem of efficient passing the roles and
gathering the returned variants from multiData().
3) Add multiData(), which populates a span of roles for a given
model index. The main advantage here is that a model can fetch
all the needed information for a given index just once, then
iterate on the span and provide data for each requested role.
Cf. this with data(), where every call has to re-fetch
the information for the index.
A couple of models have been ported to multiData(), as well as
QStyledItemDelegate.
[ChangeLog][QtCore][QModelRoleData] New class.
[ChangeLog][QtCore][QModelRoleDataSpan] New class.

If one needed to listen to a signal just once, one had to
store the QMetaObject::Connection object returned by connect()
and use it to disconnect the slot after the first signal
activation.
This has led to a proliferation of using wrappers (and enough
TMP); they usually look like this:
1) create a shared_ptr<QMO::Connection>, allocating its payload;
2) create a lambda, capturing the shared_ptr by value;
3) in the lambda, disconnect the connection (through the shared_ptr),
and call the actual slot;
4) connect the signal to the lambda, storing the returned
QMO::Connection into the shared_ptr.
This is expensive, error prone for newcomers, and tricky to
support as a general facility inside one's projects.
We can do better, just support single shot connections right
in QObject.
