From 4236e7f7ee1d78c5adfebe719afb8b8a6dcd094b Mon Sep 17 00:00:00 2001 From: Charles Yin Date: Wed, 6 Jun 2012 07:09:07 +1000 Subject: [PATCH] Refactor context2d thread logic 1. Use QQuickContext2DRenderThread for Threaded rendering 2. Make FBO target works with all render strategies 3. Remove some unnessary locks, call texture methods by invoking meta calls 4. Run existing tests with all render targets and strategies (except Cooperative) Change-Id: I0db5c91d848b86bcc1536c30d7a5804b66a817f1 Reviewed-by: Yunqiao Yin --- examples/quick/canvas/bezierCurve/bezierCurve.qml | 2 - examples/quick/canvas/clip/clip.qml | 2 - examples/quick/canvas/contents/Stocks.qml | 147 ----------- .../canvas/quadraticCurveTo/quadraticCurveTo.qml | 2 - examples/quick/canvas/roundedrect/roundedrect.qml | 2 - examples/quick/canvas/smile/smile.qml | 2 - examples/quick/canvas/squircle/squircle.qml | 2 - examples/quick/canvas/tiger/tiger.qml | 2 - src/quick/items/context2d/qquickcanvasitem.cpp | 25 +- src/quick/items/context2d/qquickcanvasitem_p.h | 2 +- src/quick/items/context2d/qquickcontext2d.cpp | 86 ++++--- src/quick/items/context2d/qquickcontext2d_p.h | 10 +- .../context2d/qquickcontext2dcommandbuffer.cpp | 5 + .../items/context2d/qquickcontext2dtexture.cpp | 274 ++++++--------------- .../items/context2d/qquickcontext2dtexture_p.h | 45 +--- .../quick/qquickcanvasitem/data/CanvasTestCase.qml | 15 +- .../auto/quick/qquickcanvasitem/data/tst_image.qml | 4 +- .../quick/qquickcanvasitem/data/tst_svgpath.qml | 9 +- 18 files changed, 172 insertions(+), 464 deletions(-) delete mode 100644 examples/quick/canvas/contents/Stocks.qml diff --git a/examples/quick/canvas/bezierCurve/bezierCurve.qml b/examples/quick/canvas/bezierCurve/bezierCurve.qml index f18c4a1..6337b12 100644 --- a/examples/quick/canvas/bezierCurve/bezierCurve.qml +++ b/examples/quick/canvas/bezierCurve/bezierCurve.qml @@ -64,8 +64,6 @@ Item { property real scaleY : scaleYCtrl.value property real rotate : rotateCtrl.value smooth:true - renderTarget:Canvas.Image - renderStrategy: Canvas.Immediate Behavior on scaleX { SpringAnimation { spring: 2; damping: 0.2; loops:Animation.Infinite } } diff --git a/examples/quick/canvas/clip/clip.qml b/examples/quick/canvas/clip/clip.qml index 3fdc3e4..55c7913 100644 --- a/examples/quick/canvas/clip/clip.qml +++ b/examples/quick/canvas/clip/clip.qml @@ -65,8 +65,6 @@ Item { property real alpha:alphaCtrl.value property string imagefile:"../contents/qt-logo.png" smooth:true - renderTarget:Canvas.Image - renderStrategy: Canvas.Immediate Component.onCompleted:loadImage(canvas.imagefile); onAlphaChanged:requestPaint(); diff --git a/examples/quick/canvas/contents/Stocks.qml b/examples/quick/canvas/contents/Stocks.qml deleted file mode 100644 index 043bca1..0000000 --- a/examples/quick/canvas/contents/Stocks.qml +++ /dev/null @@ -1,147 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2012 Nokia Corporation and/or its subsidiary(-ies). -** Contact: http://www.qt-project.org/ -** -** This file is part of the examples of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:BSD$ -** You may use this file under the terms of the BSD license as follows: -** -** "Redistribution and use in source and binary forms, with or without -** modification, are permitted provided that the following conditions are -** met: -** * Redistributions of source code must retain the above copyright -** notice, this list of conditions and the following disclaimer. -** * Redistributions in binary form must reproduce the above copyright -** notice, this list of conditions and the following disclaimer in -** the documentation and/or other materials provided with the -** distribution. -** * Neither the name of Nokia Corporation and its Subsidiary(-ies) nor -** the names of its contributors may be used to endorse or promote -** products derived from this software without specific prior written -** permission. -** -** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -** A PARTICULAR PURPOSE ARE DISCLAIMED.
