Avoid running JavaScript during animation. For example, running a complex JavaScript expression for each frame of an x property animation. +\section1 Rendering + +Often using a different graphics system will give superior performance to the native +graphics system (this is especially the case on X11). This can be configured using +QApplication::setGraphicsSystem() or via the command line using the \c -graphicssystem +switch. + +You can enable OpenGL acceleration using the \c opengl graphics system, or by setting a +QGLWidget as the viewport of your QDeclarativeView. + +You may need to try various options to find what works the best for your application. +For embedded X11-based devices one recommended combination is to use the raster graphics +system with a QGLWidget for the viewport. While this doesn't guarantee the \bold fastest +performance for all use-cases, it typically has \bold{consistently good} performance for +all use-cases. In contrast, only using the raster paint engine may result in very good +performance for parts of your application and very poor performance elsewhere. + +The QML Viewer uses the raster graphics system by default for X11 and OS X. It also +includes a \c -opengl command line option which sets a QGLWidget as the viewport of the +view. On OS X, a QGLWidget is always used. + */ diff --git a/src/s60installs/bwins/QtDeclarativeu.def b/src/s60installs/bwins/QtDeclarativeu.def index e96f83f..8fdd72c 100644 --- a/src/s60installs/bwins/QtDeclarativeu.def +++ b/src/s60installs/bwins/QtDeclarativeu.def @@ -1675,4 +1675,5 @@ EXPORTS ?setBindingForObject@QDeclarativeEngineDebug@@QAE_NHABVQString@@ABVQVariant@@_N@Z @ 1674 NONAME ; bool QDeclarativeEngineDebug::setBindingForObject(int, class QString const &, class QVariant const &, bool) ??0QDeclarativeImageProvider@@QAE@W4ImageType@0@@Z @ 1675 NONAME ; QDeclarativeImageProvider::QDeclarativeImageProvider(enum QDeclarativeImageProvider::ImageType) ?setMethodBody@QDeclarativeEngineDebug@@QAE_NHABVQString@@0@Z @ 1676 NONAME ; bool QDeclarativeEngineDebug::setMethodBody(int, class QString const &, class QString const &) + ?resetBindingForObject@QDeclarativeEngineDebug@@QAE_NHABVQString@@@Z @ 1677 NONAME ; bool QDeclarativeEngineDebug::resetBindingForObject(int, class QString const &) diff --git a/src/s60installs/eabi/QtDeclarativeu.def b/src/s60installs/eabi/QtDeclarativeu.def index 083e07f..dd5103f 100644 --- a/src/s60installs/eabi/QtDeclarativeu.def +++ b/src/s60installs/eabi/QtDeclarativeu.def @@ -1706,4 +1706,5 @@ EXPORTS _ZN25QDeclarativeImageProviderC1ENS_9ImageTypeE @ 1705 NONAME _ZN25QDeclarativeImageProviderC2ENS_9ImageTypeE @ 1706 NONAME _ZNK25QDeclarativeImageProvider9imageTypeEv @ 1707 NONAME + _ZN23QDeclarativeEngineDebug21resetBindingForObjectEiRK7QString @ 1708 NONAME |
