* Add support for unwrapping QFuture<QFuture<T>>Sona Kurazyan2022-04-211-0/+34
| | | | | | | | | | | | | | | | Added QFuture::unwrap() for unwrapping the future nested inside QFuture<QFuture<T>>. QTBUG-86725 suggests doing the unwrapping automatically inside .then(), but this will change the return type of .then() that used to return QFuture<QFuture<T>> and might cause SC breaks. Apart from that, QFuture::unwrap() might be helpful in general, for asynchronous computations that return a nested QFuture. [ChangeLog][QtCore][QFuture] Added QFuture::unwrap() for unwrapping the future nested inside QFuture<QFuture<T>>.

* QDate: add conversions for std::chrono calendaring classesGiuseppe D'Angelo2022-04-131-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | std::chrono::year_month_day and related classes offer very convenient to specify dates. This patch adds implicit constructors to QDate to support this convenience, e.g.: // YYYY-MM-DD, DD-MM-YYYY, MM-DD-YYYY formats: QDate d1 = 1985y / December / 8; QDate d2 = 8d / December / 1985; QDate d3 = December / 8d / 1985; // Indexed weekday: QDate d4 = 2000y / January / Monday[0]; QDate d5 = 2000y / January / Monday[last]; and so on. These are all implemented using the conversion from the std calendaring classes to sys_days. Conversions between sys_days and QDate are also added, since they're basically "for free". I don't expect "ordinary" users to stumble upon it, but it's worthy mentioning that std::chrono::year *does* have a year zero (hence, year_month_day in year 0 or below are offset by one with the corresponding QDate). I've left a note in the documentation. [ChangeLog][QtCore][QDate] QDate (and therefore QDateTime) is now constructible using the year/month/day/week classes available in the std::chrono library. Moreover, it now features conversions from and to std::chrono::sys_days. Change-Id: I2a4f56423ac7d1469541cbb6a278a65b48878b4a Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* Associative containers: add a way to obtain a key/value rangeGiuseppe D'Angelo2022-03-043-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our associative containers' iterator's value_type isn't a destructurable type (yielding key/value). This means that something like for (auto [k, v] : map) doesn't even compile -- one can only "directly" iterate on the values. For quite some time we've had QKeyValueIterator to allow key/value iteration, but then one had to resort to a "traditional" for loop: for (auto i = map.keyValueBegin(), e = keyValueEnd(); i!=e; ++i) This can be easily packaged in an adaptor class, which is what this commmit does, thereby offering a C++17-compatible way to obtain key/value iteration over associative containers. Something possibly peculiar is the fact that the range so obtained is a range of pairs of references -- not a range of references to pairs. But that's easily explained by the fact that we have no pairs to build references to; hence, for (auto &[k, v] : map.asKeyValueRange()) doesn't compile (lvalue reference doesn't bind to prvalue pair). Instead, both of these compile: for (auto [k, v] : map.asKeyValueRange()) for (auto &&[k, v] : map.asKeyValueRange()) and in *both* cases one gets references to the keys/values in the map. If the map is non-const, the reference to the value is mutable. Last but not least, implement pinning for rvalue containers. [ChangeLog][QtCore][QMap] Added asKeyValueRange().

* QObject: optimize the common case of findChildren(QString())Marc Mutz2021-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Outside tests, all in-tree callers of QObject::findChildren() pass no name to match, and in my experience that is also true for the vast majority of out-of-tree users. Avoid the temporary QString creation in the caller and the repeated QString::isNull() checks in the implementation by overloading findChildren() without a name argument and checking for name.isNull() only once, forking off into separate helper functions. Adjust in-tree callers that used an explicit `QString()` argument in order to pass options, which goes to show that `name` should never have been the first argument of findChilden() in the first place, even though I appreciate the symmetry with findChild() (the use-cases of which, however, are radically different). Change a `findChildren().size() == 0` call found while scanning for findChildren() calls to `!findChild()` as a drive-by. Modernize loops in the various qt_qFindChild{,ren}_helper() overloads to match how the new code looks. [ChangeLog][QtCore][QObject] Added findChildren() overload taking no name (thus optimizing this common case).

* QHash: support std::hash as hashing functionGiuseppe D'Angelo2020-11-301-0/+10
| | | | | | | | | | | | | | | | | | | | In addition (and as a fallback) from requiring qHash, add support for std::hash specializations. This catches two birds with one stone: 1) users of Qt can simply specialize std::hash for their datatypes, and use them in both QHash and stdlib unordered associative containers; 2) we get QHash support for any (stdlib) datatype that is hashable without having to overload qHash for them. [ChangeLog][QtCore][QHash] QHash, QMultiHash and QSet now support for key types anything that can be hashed via std::hash, instead of always requiring a qHash() overload.

* Replace discouraged Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPEAndreas Buhr2020-11-301-1/+1
| | | | | | | | | | | | | | Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with move semantics, its name is misleading. Q_RELOCATABLE_TYPE was introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this patch should have no impact on users.

* Clean up QCollator's documentation and tell fewer liesEdward Welbourne2020-11-271-0/+58
| | | | | | | | | | | | | | | | | | | | Its collation strategy can't be passed to the constructor, so describing it as initialized with a strategy was misleading. The "Linux without ICU" disclaimer was poorly phrased and only mentioned on one of the options; it actually applies to all. The operator() was marked internal, but the class doc's claim that QCollator can be used with std::sort() relies on it being callable. Moved option descriptions to the getters and filled in the missing ones. Mention the default in all cases. Added a minimal illustration of how to use a QCollator.
