* Add documentation for QTaggedPointerSimon Hausmann2020-03-192-8/+214
| | | | | | | | The class remains \internal though, as it has a very narrow use-case for low-level code inside Qt. Change-Id: I9d2b6486ce29b290af7f930a0bfc78590a83cc01 Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io>
* Use QTaggedPointer in QPropertyObserverSimon Hausmann2020-03-195-81/+73
| | | | | | | | | | This replaces the private tagged pointer and the use of enums for the tag makes the observer handling code more readable. The pointer-to-tagged-pointer class remains in qpropertyprivate.h due to its exoticness. Change-Id: Icc88799136c6839426d994b42368526463265e66 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

| | | | | | | | | | A generic binding allows implementing the binding function in a way that enables the QML engine to run binding scripts and convert the V4::Value into a QVariant and then assign the value to the property with the help of QMetaType::construct.

* | Make it possible to use QTaggedPointer within classesSimon Hausmann2020-03-171-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A common pattern in declarative is to use the unused bits in linked list next pointers for additional information storage. The "next" pointer is typically then a tagged pointer of the containing class, which is not fully defined yet. Therefore alignof() can't be used at tagged pointer instantiation time. This patch delays the calls to alignment, etc. until the corresponding functions are used, as in principle the tagged pointer is just a quintptr and no additional information should be needed until operating on it.

* | | High-DPI: Enable AA_UseHighDpiPixmaps by defaultMorten Johan Sørvig2020-03-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The effect of this is that QIcon::pixmap() will/may return a pixmap larger than the requested size (with an appropriate devicePixelRatio set), suitable for high-dpi displays. Many use cases, such as painting the image with QPainter, will be unaffected by this change. User code which e.g. iterate over image pixels may have to be updated.
