* Tidy nullptr usageAllan Sandfeld Jensen2019-12-061-20/+20
| | | | | | | | | | | Move away from using 0 as pointer literal. Done using clang-tidy. This is not complete as run-clang-tidy can't handle all of qtbase in one go.

* Port from QAtomic::load() to loadRelaxed()Giuseppe D'Angelo2019-06-201-19/+19
| | | | | | | | | | | | | | | Semi-automated, just needed ~20 manual fixes: $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} + $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} + It can be easily improved (e.g. for store check that there are no commas after the opening parens). The most common offender is QLibrary::load, and some code using std::atomic directly. Change-Id: I07c38a3c8ed32c924ef4999e85c7e45cf48f0f6c Reviewed-by: Marc Mutz <marc.mutz@kdab.com>

| | | | | | | | | | | | | | | | | | 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 Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination.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>
* OpenGL: Add versioned functions support for opengl 4.4 and 4.5David Morgan2015-02-091-21/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous errors in versioned function classes for OpenGL versions prior to 4.4 have also been fixed to comply with the new OpenGL xml specification. Such mistakes were due to either bugs in the old plain text specification files or problems due to the difficulty in parsing the old spec files. In some cases this has meant adding in missing functions that were absent previously. The other class of problem was when functions were erroneously included in the versioned function classes when they should not have been present. That is, some core profile classes incorrectly had member functions for deprecated functions that should only be present in the compatibility profile classes. In these cases these incorrect functions will now trigger a qFatal if called. This is fine as any applications that called these by mistake in the past would have been dereferencing a null pointer as the function pointer resolution would have failed for these functions. [ChangeLog][QtGui] Add version function classes for OpenGL 4.4 and 4.5 and deprecate some erroneously classified functions.

| | | | | | | | | | | | | | | | | | If \wrapper appears in a \class comment or a \qmltype comment, qdoc will not print warnings when it finds public members of the class or the QML type that are not documented. The \wrapper command is added to several opengl classes. This reduces the number of qdoc warnings by several thousands.

* OpenGL: Add a set of version and context specific OpenGL classesSean Harmer2013-02-261-0/+376
This commit adds part of the output of utils/glgen and some simple modifications to QOpenGLContext to allow easy access to classes containing functions specific to a given OpenGL context and version. This allows compile-time detection of mis-use of OpenGL features. For example, trying to use glBegin(GL_TRIANGLES) with an OpenGL 3.2 Core Profile context will be detected by the compiler rather than at runtime. These capabilities make it much easier to add functionality to Qt and applications that relies upon core features of OpenGL from specific versions e.g. geometry shaders.
