* Whitespace cleanup: remove trailing whitespaceAxel Waggershauser2013-03-166-51/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove all trailing whitespace from the following list of files: *.cpp *.h *.conf *.qdoc *.pro *.pri *.mm *.rc *.pl *.qps *.xpm *.txt *README excluding 3rdparty, test-data and auto generated code. Note A): the only non 3rdparty c++-files that still have trailing whitespace after this change are: * src/corelib/codecs/cp949codetbl_p.h * src/corelib/codecs/qjpunicode.cpp * src/corelib/codecs/qbig5codec.cpp * src/corelib/xml/qxmlstream_p.h * src/tools/qdoc/qmlparser/qqmljsgrammar.cpp * src/tools/uic/ui4.cpp * tests/auto/other/qtokenautomaton/tokenizers/* * tests/benchmarks/corelib/tools/qstring/data.cpp * util/lexgen/tokenizer.cpp Note B): in about 30 files some overlapping 'leading tab' and 'TAB character in non-leading whitespace' issues have been fixed to make the sanity bot happy. Plus some general ws-fixes here and there as asked for during review. Change-Id: Ia713113c34d82442d6ce4d93d8b1cf545075d11d Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@digia.com>

* OpenGL: Add code generator for OpenGL enabler classesSean Harmer2013-02-2522-0/+5261
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a code generator that can be executed offline to generate a few classes for enhancing Qt's support for OpenGL. The generated code effectively provides all the benefits of GLEW in its multi-context form but for all platforms and even for ES2. The code generator takes as input the official Khronos gl.spec specification and gl.tm typemap files. These provide all of the information required to create the OpenGL Desktop related classes. The classes for ES2 are hand-crafted as no similar spec files have been published. The generated code supports all OpenGL extensions listed in the Khronos registry for both Desktop OpenGL and ES 2. There is a helper factory class generated which are used by QOpenGLContext::versionFunctions(). This allows code like the following to be written: QOpenGLFunctions_3_3_Core* m_funcs = 0; m_funcs = m_context->versionFunctions<QOpenGLFunctions_3_3_Core>(); if (!m_funcs) { qWarning() << "Could not obtain required OpenGL context version"; exit(1); } if (!m_funcs->initializeOpenGLFunctions()) { qWarning() << "Failed to resolve entry points"; exit(2); } // Get an extension object QOpenGLExtension_ARB_draw_buffers* ext = 0; if (m_context->hasExtension("GL_ARB_draw_buffers")) { ext = new QOpenGLExtension_ARB_draw_buffers(); ext->initializeOpenGLFunctions(m_context); } Such usage will allow much easier and rigorous use of features in modern OpenGL and extensions both in Qt itself and by users of Qt. Follow-up patches will import the generated files and then use these to reinstate OpenGL geometry shaders, add tessellation shaders, and other OpenGL constructs.

* | Stop relying on qHash always giving the same resultsGiuseppe D'Angelo2012-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of the various qHash overloads offered by Qt can change at any time for any reason (speed, quality, security, ...). Therefore, relying on the fact that qHash will always give an identical result across Qt versions (... across different processes, etc.), given identical input, is wrong. Note that this also implies that one cannot rely on QHash having a stable ordering (even without the random qHash seed). For such use cases, one must use f.i. a private hash function that will never change outside his own control. This patch adds a private hash function for QStrings, which is identical to the Qt(4) qHash(QString) implementation. A couple of spots in Qt where the results of a qHash call were actually saved on disk are ported to use the new function, and a bit of documentation is added to QHash docs.
