* Use QSGEngine instead of the private QSGRenderContextJocelyn Turcotte2014-08-061-6/+1
| | | | | | | | | QSGEngine was added in Qt 5.4 to allow using the scene graph without QQuickWindow. Use it for our FBO as well as for the QOpenGLWidget rendering. Change-Id: If4665d4f33c9dad69d2d4269309163bb5ffbd8e3 Reviewed-by: Andras Becsi <>
* Use a fence sync to synchronize GL between threadsJocelyn Turcotte2014-04-101-0/+3
| | | | | | | | | | | | | | | | | The NVidia driver needs more than a glFlush to ensure that GL commands consuming Chromium resources are run only when the resource is completely produced by the Chromium GPU thread. This produces artifacts and an uneven frame rate in WebGL examples on this kind of hardware. Use the same mechanism as used by gfx::GLFence, doing a few things manually to cope with the fact that Chromium and Qt both have their own GL function table and contexts.

* Render the widgets view using the scene graph into a QOpenGLWidgetJocelyn Turcotte2014-04-081-3/+3
| | | | | | | | | | | | | | | This means that widgets application now need to setup the GL context sharing as well. QWebEngineWidgets::initialize() must be called, which has the same effect as QWebEngine::initialize(). The QtWebEngineWidgets now depends on the QtWebEngine module to make this happen. Since QOpenGLWidget is only available in Qt 5.3, this patch also disables the webenginewidgets module completely when building using Qt 5.2.

* Fix the HighDPI rendering of QQuickWebEngineViewJocelyn Turcotte2014-03-201-1/+3
| | | | | | | | | | | | | Use the ratio given with the compositor frame instead of taking it directly from the QWindow to make sure that we scale according to the rasterizing of the tiles. Set the scale directly on the DelegatedFrameNode by making it a QSGTransformNode to avoid creating an extra QSGNode.

* Quick: Support reparentingArvid Nilsson2014-01-311-2/+12
| | | | | | | | | | | | | | | | | To support reparenting, we make the compositing surface independent of the window by using gfx::TEXTURE_TRANSPORT. We also need to be able to keep frame data across window changes so we can reconstruct the QSGNode tree in a new context, so extract that data into DelegatedFrameNodeData class. Any context-specific data is still stored in DelegatedFrameNode. Also hook up window changes to WebContents::WasShown/Hidden for Quick. Remove checking of Qt isVisible state, this mechanism is used to sync Chromium with Qt, not the other way around. WasShown/Hidden is orthogonal to Show/Hide, and can use different triggers. However for Widgets it probably makes sense to hook both up to widget visibility. Change-Id: I1ef4b50cd61b8e54b791e03f0b41929c42fec8bf Reviewed-by: Jocelyn Turcotte <>
* Moving sources to src part 1: Move files.Jocelyn Turcotte2013-11-281-0/+87
This only move files without adjusting any paths. This moves: - lib/quick -> src/webengine/api (API files) lib/quick -> src/webengine (other files) This contains the main QtWebEngine module library since <ec7b2ee70a8b2db7fb87f50671a001ddd54697b0>. - lib/widgets -> src/webenginewidgets Also rename this directory to match its module name and rename Api to api. - lib -> src/core - process -> src/process - resources -> src/core/resources - tools/* -> tools/scripts/ The build directory is spread as follow: - build/ -> src/core/ - build/qmake_extras/* -> src/core/ (for the host and target .pro files) - build/qmake -> tools/qmake - Build related scripts -> tools/buildscripts Change-Id: I0cded1de772c99c0c1da6536c9afea353236b4a1 Reviewed-by: Zeno Albisser <> Reviewed-by: Pierre Rossi <> Reviewed-by: Andras Becsi <>
