Rename Qt Quick-specific classes to QQuick* The QSG (SceneGraph) prefix is too generic for Qt Quick(2)-specific classes. All the classes and files in the declarative/items directory have been renamed. In particular, for classes that are currently public, the renaming is as follows: QSGView --> QQuickView QSGCanvas --> QQuickCanvas QSGItem --> QQuickItem QSGPaintedItem --> QQuickPaintedItem The header files have been renamed accordingly (e.g. qsgview.h --> qquickview.h).

Add a way to set the default render type of text-like elements f3446071da8357620d0c8593a04e3b4fbba88f21 introduced a build-time way to select the default render type of text-like elements. This patch adds also a way to select it at runtime, via a setter on QQuickWindow. (QQuickWindow has been chosen as convenience, rather than adding another namespace/class to just have this setter.) Given that QT_QUICK_DEFAULT_TEXT_RENDER_TYPE was never documented, I've taken the liberty of changing the accepted values for it (to match the new enumerator names in QQuickWindow, rather than the ones in QQuickText/QQuickTextEdit/etc.). [ChangeLog][QtQuick][QQuickWindow] It is now possible to set the default render type of text-like elements globally via the QQuickWindow::setTextRenderType() function. If you were using the (undocumented) QT_QUICK_DEFAULT_TEXT_RENDER_TYPE macro when building Qt Quick for the same purpose, note that the macro value needs now to be set to the "NativeTextRendering" value, instead of "NativeRendering".

QQuickText: Don't store node engine per node. Since these are only used during one particular phase of dealing with text, it is extremely wasteful to heap allocate them and keep them around for the entire lifetime of the node (~3kb of total allocation _each_ according to OS X). Removing these cuts around 100mb of transient allocations off the qmlbench text creation benchmark (and takes the total allocations during a test run from ~496 MB to ~389 MB). It also improves the approximate throughput for creation of text items by ~5%.

Optimize QQuickTextEdit for larger documents. The rationale is to not end up re-processing the whole document on each update Since we know where the editing takes place, we can break down the text edit's contents in several text nodes and only re-create the affected text nodes upon editing. This requires ripping out the SelectionEngine helper class from QQuickTextNode so that QQuickTextEdit can tap into its functionality directly. A positive side-effect of this exercise is that it should be much harder to to come across GlyphNodes packing more than 16300 glyphs or so.

Otherwise the rect we e.g return from cursorRect() will be invalid. An alternative would be to use the width of the delegate, but that was found to be controversial. On iOS we saw a bug with this when telling iOS to position text spelling popups underneath the cursor. Since the cursor rect we got was invalid (zero-width), no popup would show.

TextEdit: deal with scrolling backwards in rich text A bug was introduced in 9db23e0e04906cf9ea33e23fa41f34955e5e6fe0 : when scrolling backwards in some kinds of rich text, updatePaintNode() failed to re-populate the nodes that had been scrolled out above the viewport. That was because those nodes had been removed from textNodeMap, and then firstDirtyPos was set from the first node in textNodeMap. For some reason this didn't happen with the markdown document that I was testing (maybe because it had a table and an image near the beginning), but showed up when viewing an html document similar to the one we ship with the rich text example. So now we iterate backwards from textNodeMap.begin() when this happens, to find all nodes in the current frame that intersect the viewport as rendered. In the autotest we now use font.pixelSize in an attempt to make the rendered text ranges more consistent across platforms in CI; and we need to wait for the rendering to be redone after scrolling.

Invalidate text when application fonts are added or removed We had multiple related issues due to application fonts being added or removed during the application lifetime. 1. If a text had font family "foo" set, and this font did not exist at the time, then loading "foo" at a later stage would not update the text to use the correct font, since the result of the previous request had been cached. 2. A variation of #1 was if the font "foo" was loaded by a FontLoader in the scene and referred to by name in the text component. In this case, there was a race condition, where the font lookup would sometimes yield different results on the main thread and on the render thread, and text would be garbled. 3. When a font was removed from the font database, then references to it would remain in the caches (glyph cache + font cache) in the render thread. With certain backends (DirectWrite, CoreText) this caused errors or even crashes, as the cached font engines would be referring to data that had been removed. The work-around for #1 and #2 was merely to avoid hardcoding names for fonts, but instead getting them from the FontLoader. This way, you can avoid requesting the font family before it is available (and thus avoid caching the wrong result). However, for #3 there is no known work-around. This patch fixes all three (together with a smaller patch for qtbase) by invalidating all text and related caches in Qt Quick when fonts are either added or removed from the font database. This does add some overhead if font loading happens during runtime, but the alternative is broken behavior and dangling pointers. This is done during the synchronization step. Before synchronization, the font cache is flushed and all text components are marked for update, so that fonts are re-requested against the new font database. After synchronization, we delete all distance field glyph caches which are not currently in use, to avoid having references to stale application font data in the list. [ChangeLog][Text] Fix multiple issues with usage of application fonts when they are added or removed during the lifetime of the application.

In particular, for classes that are currently public, the renaming is as follows: QSGView --> QQuickView QSGCanvas --> QQuickCanvas QSGItem --> QQuickItem QSGPaintedItem --> QQuickPaintedItem The header files have been renamed accordingly (e.g. qsgview.h --> qquickview.h).

Defer construction of TextEdit/TextInput delegates. Don't create instances of the delegate components until the item gains focus, or the cursorVisible property is set to true. Cursor delegates are typically small and relatively fast to create and so won't have a significant cost during a one off focus in event, but that cost can still add up when creating a number of TextInputs or TextEdits at once. If a delegate that is instantiated immeditately is required it is possible to instead create a child item and bind to the cursorRectangle and cursorVisible properties.

Optimize QQuickTextEdit for larger documents. The rationale is to not end up re-processing the whole document on each update Since we know where the editing takes place, we can break down the text edit's contents in several text nodes and only re-create the affected text nodes upon editing. This requires ripping out the SelectionEngine helper class from QQuickTextNode so that QQuickTextEdit can tap into its functionality directly. A positive side-effect of this exercise is that it should be much harder to to come across GlyphNodes packing more than 16300 glyphs or so.

TextEdit large text: don't populate blocks outside the viewport into SG When the text is larger than 10000 characters, we now avoid creating nodes for blocks that go outside the viewport. Each time the text moves relative to the viewport, we check whether the rectangular area that we know is "covered" with the text rendered so far is still enough to fill the viewport; if not, update the whole document: mark all existing SG nodes dirty, then delete and re-create them. [ChangeLog][QtQuick][Text] When given large text documents (QString::size() > 10000), Text and TextEdit now try to avoid populating scene graph nodes for ranges of text that fall outside the viewport, which could be a parent item having the ItemIsViewport flag set (such as a Flickable), or the window's content item. If the viewport is smaller than the window, you might see lines of text disappearing when they are scrolled out of the viewport; if that's undesired, either design your UI so that other items obscure the area beyond the viewport, or set the clip property to make clipping exact.
