* Revert "Update commercial license headers"v6.2.5-lts-lgplTarja Sundqvist2022-11-241-21/+21
| | | | | | | | | | | This reverts commit 90c32995096ae90eb3c6f2da407488c5c063657f. Revert of commercial license headers is required for the Qt 6.2.x opensource releases, Qt 6.2.5 onwards.

* Update commercial license headersTarja Sundqvist2022-06-211-21/+21
| | | | | | | | | | | | | | | Updated header.COMM to the files in tqtc-qtbase. Examples, tests, or documentation files are not updated. The commercial license header may contain some additional lines so that its line count equals with the earlier license header. Reason for this is that some autotests use hard coded line numbers and a change in the line count causes failures in tests.

* macOS: Don't scroll individual rects of a region when inline scrollingTor Arne Vestbø2022-04-011-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QPlatformBackingStore::scroll() API takes a QRegion as input, and we kept this data type in the implementation of QCALayerBackingStore::scroll for the logic of figuring out whether we could use the existing back buffer as source of the scroll or if we needed to pull data from the front buffer. We then iterated the rects of the resulting in-line region, and called qt_scrollRectInImage for each of them. This will unfortunately not work whenever the scroll of one of these rects ends up overwriting parts of the back buffer that later rects of the region use as their source rect. This could be reproduced by moving the cursor within a text document, which would dirty a small area around the cursor, making the subsequent scroll of the viewport result in garbled text. This issue exists in the other platform backingstore implementations too, but since the QWidgetRepaintManager never calls scroll() with anything but a single rect they would not have any issues. The problem could potentially be solved by sorting the rects before blitting them, but now this quick fix solves the regression on macOS.

* macOS: Implement QCALayerBackingStore::scroll for improved performanceTor Arne Vestbø2022-01-171-0/+55
| | | | | | | | | | | | | | | | | | | The CALayer backingstore never had a scroll implementation because we were relying on the QRasterBackingStore implementation, but as it turned out that implementation was not applicable for the CALayer backingstore. We now implement scroll() by determining which part of the back buffer can be scrolled directly in-place, and then scrolling the rest by copying from the front buffer. We have to handle both cases, as clients may scroll multiple times before flushing, and the scrolled area may overlap both valid back-buffer content and content that needs to be pulled from the front-buffer.

* macOS: Don't defer back/front-buffer swap in CALayer backingstoreTor Arne Vestbø2021-11-081-25/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | CoreAnimation doesn't immediately mark a surface as in use the moment we assign it to a layer, but defers it until the surface has bee picked up by the window server. In theory this would allow us to defer the swap until the next beginPaint(), which would allow painting to the back buffer again before Core Animation has time to flush the transaction and persist the layer changes to the window server, and would also automatically deal with requests to flush without painting anything. But, since a client may do several rounds of beginPaint/endPaint before flushing, we might end up in a situation where we detect that a surface is in use in the middle of several paint rounds, and end up swapping in a new back buffer without copying over the previously painted content, like we do in prepareForFlush. To be on the safe side we swap the back and front buffer straight away. We also need to mark the surface in use, to prevent the same problem from appearing when the window server doesn't pick up the surface in between two rounds of flushes.

| * macOS: Flush sublayers via separate IOSurface backingstoresTor Arne Vestbø2020-03-251-24/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flushing sublayers via QImage copies of the root IOSurface was causing performance regressions due to the constant allocations of new images each frame. We now re-use the QCALayerBackingStore implementation for sublayers, which gives a dynamic swap-chain. We're still paying the CPU cost of the copy from the root backingstore to the layered backingstores, as well as the memory cost, but at least improves the situation. We do not try to be smart and paint directly into the sublayers, as that would leave the root backingstore stale, potentially causing glitches when views are repositioned. Investigating this is left for future work.

We used to do this by assigning the display's color space, which effectively opts out of color matching, similar to the old behavior of the device RGB color space (which nowadays implies sRGB). By picking up the color space from the NSWindow instead, we allow the user to override the color space to trigger color matching, for example by explicitly setting it to NSColorSpace.sRGBColorSpace. NSWindow will fall back to the screen's color space if the window doesn't have one set.

| | | | | | | | | | | | | | | | | | | | | | It's not part of the QBackingStore API, but clients such as the Qt Quick software renderer access it through the platform backingstore, to grab the window.

* | macOS: Track screens via Quartz Display Services instead of NSScreenTor Arne Vestbø2019-05-131-12/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Using NSScreen as the basis for tracking screens is not recommended, as the list of screens can be added, removed, or dynamically reconfigured at any time, and the NSScreen instance, or index in the NSScreen.screens array may not be stable. Quartz Display Services on the other hand tracks displays via a unique display ID, which typically remains constant until the machine is restarted. The lower level API also gives us earlier callbacks about screen changes than the corresponding NSApplicationDidChangeScreenParametersNotification does. By reacting to screen changes _before_ AppKit does, we can remove workarounds for receiving window move and screen change notifications before the screen was actually visibly reconfigured. The new approach also handles changes to the primary screen, which can happen if the user moves the menu bar in the macOS display arrangement pane. The device pixel ratio of the screen has been made into a cached property, like all the other properties of QCocoaScreen. This is more consistent, and allows us to qDebug the screen even when it has been removed and we no longer have access to resolve the properties from the associated Quarts display.

* macOS: Gracefully handle devicePixelRatio mismatch in QCALayerBackingStoreTor Arne Vestbø2019-04-191-3/+20
| | | | | | | | | | | | If the client of the backingstore fails to pick up dpr changes, and tries to flush the backingstore without a repaint, we will end up flushing a back-buffer with a stale dpr. Detect when this happens, warn the user, and smooth out the situation by adjusting the layer accordingly.

* macOS: Add IOSurface based backingstore for layer-backed viewsTor Arne Vestbø2019-03-141-108/+435
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The naïve approach used for layer-backing in the past caused a detach of the backingstore QImage on each beginPaint, since the image was assigned to the layer via a CGImageRef that participated in the QImage implicit sharing (and had to, so we couldn't get around that). We now use IOSurfaces, wrapped in a QPlatformGraphicsBuffer abstraction. The surfaces can be assigned to the layer's content the same way images could, but allows us to reason more closely about whether or a buffer is in use, and increases the chance that we will have a zero-copy path to the screen. Unless the window has requested a surface format with single buffering we use a dynamic swap chain of buffers. In most situations there will be two buffers in play, one assigned to the layer and one ready to paint to, but during resize and some other situations the buffers will grow temporarily to accommodate the increased back-pressure. Since QBackingStore is documented as having single-buffer behavior, we take care to persist content between the buffers before every swap. By doing this before swapping, instead of before each paint, we can avoid preserving areas that will be painted to anyways, and will in many situations (such as blinking cursors e.g.) end up not persisting anything. The RasterGL surface case is handled by reading out the buffer data and doing a manual texture upload. In the future we can support direct texture access via CGLTexImageIOSurface2D, but this requires QPlatformBackingStore::composeAndFlush to learn how to support other targets than GL_TEXTURE_2D, as CGLTexImageIOSurface2D only works with GL_TEXTURE_RECTANGLE_ARB targets.

| | | | | | | | | | | | | | | | | | | | | | | | | | If there's no background, we should copy the backingstore, so that the backingstore is not blended with the result of the previous flush.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When flushing parts of a QBackingStore onto child QWindows, and we're in layer-backed mode, we need to set the contentsRect of the layer so that the layer will only show the part of the top-level-owned backingstore image that's relevant for the child window. Since the contentsRect is in unit coordinate system, we need to apply a transform, but this must be based on the top level view's size, not the image size, as the latter will be twice as big on a retina screen, giving the wrong unit rect.
