* Fix some qdoc warnings: printer API cleanupVolker Hilsheimer2020-09-221-107/+0
| | | | | | | | | | | | Puge references from removed QPrinter methods. QPdfWriter's setter API documentation only added the word "PDF" to the QPagedPaintDevice documentation. This was not useful - when the latter talks about "page", it's obvious what is meant in the context of PDF, so remove the duplication.

* Define inverted QRects consistentlyAllan Sandfeld Jensen2020-09-211-35/+3
| | | | | | | | | | | | | | | | Changes the definition of invalid QRects to be more consistent. This simplifies the logic, and makes it possible for us to fix normalized() so dimensions don't change. The actual API is not changed except for inverted rects. Only one use-case for the old normalized() function existed, and has been reimplemented as QRect::span().

* 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.
