* Centralize the implementation of move assignment operatorsGiuseppe D'Angelo2020-10-031-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we have two main strategies for dealing with move assignment in Qt: 1) move-and-swap, used by "containers" (in the broad sense): containers, but also smart pointers and similar classes that can hold user-defined types; 2) pure swap, used by containers that hold only memory (e.g. QString, QByteArray, ...) as well as most implicitly shared datatypes. Given the fact that a move assignment operator's code is just boilerplate (whether it's move-and-swap or pure swap), provide two _strictly internal_ macros to help write them, and apply the macros across corelib and gui, porting away from the hand-rolled implementations. The rule of thumb when porting to the new macros is: * Try to stick to the existing code behavior, unless broken * if changing, then follow this checklist: * if the class does not have a move constructor => pure swap (but consider ADDING a move constructor, if possible!) * if the class does have a move constructor, try to follow the criteria above, namely: * if the class holds only memory, pure swap; * if the class may hold anything else but memory (file handles, etc.), then move and swap. Noteworthy details: * some operators planned to be removed in Qt 6 were not ported; * as drive-by, some move constructors were simplified to be using qExchange(); others were outright broken and got fixed; * some contained some more interesting code and were not touched.

* QEasingCurve: implement move constructorMarc Mutz2012-02-211-0/+1
| | | | | | | | | | | | | | | | | | | | | The move constructor sets other.d_ptr to zero. This is safe, because after being moved from, the object is left in a state in which it can be safely destroyed (delete nullptr is a no-op). It cannot meaningfully be used anymore (most members will crash with a nullptr dereference), but in most cases, the moved-from object cannot be accessed anyway (not a named object), and if a named object is moved from, it must have been through explicit std::move(), as in the test case. The STL makes better guarantees (moved-from containers are .empty()), but I don't think it's worth introducing a null state into QEasingCurve just for supporting a use-case that should be considered a bug anyway.

* QEasingCurve: return QVector for cubic spline representationMarc Mutz2012-02-181-2/+9
| | | | | | | | | | | | | | QEasingCurve internally holds the spline data in a QVector<QPointF>. For the return from cubicBezierSpline(), the vector is transformed into a QList<QPointF>. This involves copying, and into an inefficient (for QPointF payloads) container at that, so deprecate cubicBezierSpline() in favour of a new toCubicSpline() returning the QVector directly.

* Adding custom bezier easing curves to QEasingCurveThomas Hartmann2011-11-021-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | I added the possibilty to define Bezier/TCB splines and use them as custom easing curves. Note: Splines have a parametric definition. This means we have a function/polynom of t that evalutes to x and y. x/y = f(t). For our purpose we actually need the function y = f(x). So as a first step we have to solve the solution x = f(t) for a given t and then in a second step we evaluate y = f(t). f(t) is a cubic polynom so we use cardanos formula to solve this equation directly. For the casus irreducibilis we need 3 functions that are a combination of arcos and cos. Instead of evaluating arcos and cos we approximate these functions directly. TCB splines are converted into the corresponding cubic bezier spline. Change-Id: Id2afc15efac92e494d6358dc2e11f94e8c524da1 Reviewed-by: Aaron Kennedy <aaron.kennedy@nokia.com>
