* QtGui: use printf-style qWarning/qDebug where possible (I)Marc Mutz2016-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The printf-style version of QDebug expands to a lot less code than the std::ostream-style version. Of course, you pay in type safety (but compilers warn about it these days), you cannot stream complex Qt types and streaming QStrings is awkward, but in many cases you actually improve on readability. But the main reason is that something that's not supposed to be executed under normal operation has no business bloating executable code size. This is not an attempt at converting all qWarnings() to printf-style, only the low-hanging fruit. In this first part, replace qWarning() << "..."; with qWarning("..."); In QTransform shared warning strings. Saves 3KiB in text size on optimized GCC 5.3 AMD64 builds.

* Expose GLES 3.0 and 3.1 functionsLaszlo Agocs2015-07-231-125/+4129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the approach we already do for some GLES 3.0 functions we can provide a cross-platform, cross-GL-GLES wrapper for ES 3.0 and 3.1 functions too. Applications only have to take extra care about the version requests (context version and version directives in shader code), the rest of their code can stay the same across desktop/mobile/embedded, even when ES 3 functions are used. The new functions are placed to a new subclass which is placed between QOpenGLFunctions and the internal QOpenGLExtensions. This is necessary because, unlike with QOpenGLFunctions, there is no guarantee that these functions are always available in all configurations. When running on desktop OpenGL, we resolve as usual. If the OpenGL version contains the function in question, either in core or as an extension, it will all just work. This is handy because it does not rely on 4.x extensions like GL_ARB_ESx_compatibility, and so ES 3.0 functions will be functional on OpenGL 3.x systems too by just setting a 3.x version number in the QSurfaceFormat. We will no longer qFatal on broken systems where the driver returns a 3.0 or 3.1 context without the corresponding functions present. Instead, we show a warning and gracefully fall back to resolving as usual, via eglGetProcAddress or similar. For functions that are available in ES2 as an extension this may just work fine. Added also an example that runs identically both with OpenGL and OpenGL ES 3 and utilizes some ES 3.0 features like instanced drawing. [ChangeLog] Added QOpenGLExtraFunctions providing OpenGL ES 3.0 and 3.1 function wrappers in a cross-platform manner.

* Use glFinish() in QOpenGLWidget unless glFlush() is known to be enoughLaszlo Agocs2015-03-231-1/+31
| | | | | | | | | | | | | | | | | | | | The driver used on the Odroid-XU3 does not like doing just glFlush() before accessing the texture in another context. There is no guarantee that glFlush() is enough to sync access to resources between contexts, so start using glFinish() as the default, except on common desktop hw + iOS where flush is enough and presumably more efficient. To unify the code pathes, remove the separate flushes and do it only once, before the backingstore compositor indicates that it is about to access the textures. This should improve performance a bit, esp. when doing multisampling since we flush only once then. A helper function is added to the internal QOpenGLExtensions because it is highly likely that QQuickWidget will need the same.

* Prevent crashing on ES2 SDK - ES3 device scenarios with AndroidLaszlo Agocs2015-02-121-1/+4
| | | | | | | | | | | | | | Making a build with an older NDK having only gl2.h results in crashing QOpenGLTexture on devices that provide ES 3.0 or 3.1. This is because immutable storage is supported (based on runtime checks) but the function pointers are not there (due to ifdef checks). Fix this like we did in other places: get rid of the ifdef and dlsym the ES3-only symbols.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
