* QPdf: consolidate usage of uintGiuseppe D'Angelo2020-10-192-3/+4
| | | | | | | | | Objects in QPdf are indexed by uint. In a couple of places (incl. QFontSubset) int were used instead, causing sign conversion warnings (turned into errors by -Werror). Use uint instead. Change-Id: Ie0436c8aff3b67d8ef95a5f26fc16403e7e02bd1 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

* Centralize the implementation of move assignment operatorsGiuseppe D'Angelo2020-10-038-23/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Introduce QWindow::paintEvent with QPA plumbingTor Arne Vestbø2020-08-261-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The explicit paint event on QtGui and QPA level allows us to untangle the expose event, which today has at least 3 different meanings. It also allows us to follow the platform more closely in its semantics of when painting can happen. On some platforms a paint can come in before a window is exposed, e.g. to prepare the first frame. On others a paint can come in after a window has been de-exposed, to save a snapshot of the window for use in an application switcher or similar. The expose keeps its semantics of being a barrier signaling that the application can now render at will, for example in a threaded render loop. There are two compatibility code paths in this patch: 1. For platform plugins that do not yet report the PaintEvents capability, QtGui will synthesize paint events on the platform's behalf, based on the existing expose events coming from the platform. 2. For applications that do not yet implement paintEvent, QtGui will send expose events instead, ensuring the same behavior as before. For now none of the platform plugins deliver paint events natively, so the first compatibility code path is always active.
