* Replace usage of QSignalMapper by lambdaOlivier Goffart2017-02-141-1/+0
| | | | | | | | | | | | | | | | | QSignalMapper ought to be deprecated soon. It simplifies the code, too. There is still one use in QQuickGenericShaderEffect which is a bit complicated to get rid of. A very similar use of QSignalMapper was in use in QQuickOpenGLShaderEffectCommon but was removed in commit 8c745d80, the same should be done for QQuickGenericShaderEffect. (Note the QueuedConnection in qquickparticlesystem is there because the QSignalMapper used to be in the main thread, meaning a round-trip via the event loop) Change-Id: I331b787becbad37f717035bf119bafd7a7214630 Reviewed-by: Frederik Gladhorn <frederik.gladhorn@qt.io>

* QtQuick: fix use-after-free of shader property connectionsErik Verbruggen2016-07-111-0/+4
| | | | | | | | | | | | A use-after-free would occur if the sender of a connection would disconnect (and destroy the slot object), and then the receiver would try to clean-up and access the slot object again. The fix is to have the receiver take out a reference to the slot object, because it will manage the life-time, and thus delete the slot object when it doesn't need it anymore.

* QtQuick: clean up shader effect property connectionsErik Verbruggen2016-07-051-8/+18
| | | | | | | | | | | | | | | - Don't use a signal mapper, but handle the mapping using a custom slot object and a lambda to do the dispatching ourselves. - Don't do meta-calls by property name, but by index. - Cache the meta-object. - Resolve the property indices by using the QML property cache. For a shader with 6 property connections, the time spent goes from 320k instructions to 80k instructions (valgrind on x86_64).

* Add a core profile file selector to OpenGL ShaderEffectLaszlo Agocs2016-07-011-1/+3
| | | | | | | | | | | Similarly to what we do with "hlsl" in the D3D12 backend, we can use "glslcore" to provide a file-based alternative to the GraphcsInfo or OpenGLInfo-based conditions in the fragmentShader and vertexShader properties. This is particularly useful in a few places inside Qt, for example Quick Controls, that have to cater to all possiblities.

* Unify ShaderEffect property settingLaszlo Agocs2016-06-291-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rendererInterface() should not require isSceneGraphInitialized() to be true - the API and language queries like graphicsApi() have no need for the scenegraph, they only need the plugin to be loaded, i.e. that the QQuickWindow is constructed. This is the key to be able to make GraphicsInfo report graphicsApi and shaderType with the correct values as early as possible - meaning as soon as the item is associated with a window. The initialization of the scenegraph (the exact timing of which varies backend to backend) does not matter here. The fragment and vertex shader property setting is now unified in the two ShaderEffect implementations: - If the component is complete, the shader is attempted to be processed right from the setter. - Otherwise the item will trigger processing once the component is complete. - If there is no window when processing is trigerred, it is deferred via polish. To implement item polish handling we need a new virtual in QQuickItemPrivate since we cannot intrdouce virtuals into the public classes. This way one can write a condition (and later potentially use file selectors) like this: fragmentShader: GraphicsInfo.shaderType == GraphicsInfo.GLSL ? "..." : ... without having to worry about getting an unintended value processed due to GraphicsInfo not yet reporting an up-to-date value. parseLog() forces, for GL at least, shader processing to prevent autotests from breaking.

* Route ShaderEffect through the old GL implLaszlo Agocs2016-04-131-39/+17
| | | | | | | | | | | | | | Register the common QQuickShaderEffect class as ShaderEffect to QML. In case of GL this will route to QQuickOpenGLShaderEffect. For others the default no-op implementation is used (at least for now). Later this new implementation will route to a backend-specific scenegraph node via the adaptation layer. This also means that QQuickOpenGLShaderEffect is no longer a QQuickItem and QQuickShaderEffect must handle everything item-related and forward.

* Prefix GL-specific shader effect codeLaszlo Agocs2016-04-131-0/+209
Rename the C++ sources and classes. The QML type name remains the same. No changes in functionality. The shader effect, node, material (and uniform animator and particles and bits and pieces here and there...) are highly interconnected and do not follow the usual design practices for Quick and the scenegraph and the adaptation layer. Therefore while we aim for keeping full compatibility for GL apps, other backends will likely get a different ShaderEffect item implementation. The C++ class QQuickShaderEffect itself is currently a dummy with an unchanged API. It is not in use for now but forms the basis for the implementation for other backends. This will be covered in future commits. Change-Id: Ia39ce4b303f8f33e2f241d11e35fa62423e43127 Reviewed-by: Andy Nichols <andy.nichols@theqtcompany.com>
