| * | Fix performance regression in rich text with imagesEskil Abrahamsen Blomfeldt2016-11-141-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a3da23d5a92ab0f9b8280b9ed591986f8ac6a2d6 we added linear filtering to the image node in rich text when smooth was set to true (which it is by default). But we also enabled mipmapping, which caused a bad performance regression when updating the text item. If we want to support mipmapping, we would have to add a separate property for this like in the image node, but since the original bug report only called for supporting smooth scaling like in Image, we can simply revert part of the change. [ChangeLog][QtQuick][Text] Fixed a performance regression when rendering a rich text item with scaled images.

* | | Add cross-backend simple rect, texture, and ninepatch nodesLaszlo Agocs2016-06-221-3/+3
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QSGSimpleRectNode is deprecated -> use QSGRectangleNode via QQuickWindow::createRectangleNode() instead. QSGSimpleTextureNode is deprecated -> use QSGImageNode via QQuickWindow::createImageNode() instead. The OpenGL version of the simple rectangle node is switched over to the vertex color material instead of flat, to allow for better batching. Use the same concept for nine patch nodes. The "style" node from Quick Controls 1 is now QSGNinePatchNode in order to provide a proper cross-backend solution which is already necessary due to the software backend, but now generalize it to apply to the accelerated backends with proper materials as well. QC can now simply call createNinePatchNode() without further ado. Also fixes a bug with the D3D12 texture material not enabling blending when needed. When it comes to the internal class names, QSGRectangleNode and QSGImageNode get the Internal prefix in the adaptation layer in order to differentiate from the public API. This involves quite a lot of renaming, but results in a nice and clean public API. Change-Id: Iddf9f9412377843ea6d652bcf25e68d1d74659ea Reviewed-by: Gunnar Sletta <gunnar@sletta.org>

| | | | | | | | | | | | | | | 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%.

* Fix cursor blinking for TextInput and TextEditSimon Hausmann2014-08-261-0/+8
| | | | | | | | | | | | | | | Before commit fb339b21b8a24b835cea7a057c47b7c5ad80dd72 relied on the simple transparent rectangle node to remain invisible. After that commit we used the regular rectangle node, which doesn't seem to like toggling the color between transparent and solid black and therefore the cursor was always visible. As advised by Gunnar this patch implements a much simpler logic: When the cursor is supposed to be invisible, we just don't create a scene graph node for it anymore.

* Optimize QQuickTextEdit for larger documents.Pierre Rossi2013-03-201-1094/+35
| | | | | | | | | | | | | | | | | 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.

* Fix preedit text visibility for TextEditJiang Jiang2012-01-161-30/+55

Also fixed preedit text appended at the end of any commited text. Move the code for adding text into SelectionEngine so that we can reuse it for adding preedit text.
