* OpenGL: Use official glext.h and gl2ext.h headersSean Harmer2012-08-201-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Khronos group makes the glext.h (Desktop OpenGL) and gl2ext.h (OpenGL ES2) headers officially available nowadays. Most (all?) Linux systems ship this by default. On Windows platforms the glext.h file needs to be downloaded from http://www.opengl.org/registry/api/glext.h and placed alongside the system OpenGL header. Making use of the official header reduces the maintenance overhead for OpenGL support in Qt by removing the need to copy and paste definitions into the Qt sources. As the Khronos-provided headers are standardised and backwards and forwards compatible we can utilise these for all platforms rather than just for Windows. This means that all definitions required by Qt will be present even if the system ships out-dated equivalents. Mac OS X needs special handling in that we should always use the system-provided headers there. This is because Apple controls the OpenGL driver and the headers that go along with it. As such there is no possibility that the driver exposes additional functionality compared with the system-provided OpenGL headers. Apple has also decided to make different decisions about some OpenGL typedefs compared to other implementations. For example, Apple typdefs GLhandleARB to void* whereas other platforms use unsigned int. The alternative, which is to use the system provided glext.h (or gl2ext.h) header means that Qt code would need to check for the availability of such definitions wherever it is not guaranteed to be provided by core OpenGL/ES just to compile. The proposed approach means that Qt can compile regardless of the system's OpenGL extension support. We just need to be rigourous in runtime checking of support for extensions but that is already a requirement (and is missing in a few places, see TODO's added in this commit). The official Khronos headers are added to Qt as qopenglext.h - Desktop OpenGL qopengles2ext.h - OpenGL ES2 They need to be public but not part of QtGui module include, hence the headers have been modified by adding #if 0 #pragma qt_no_master_include #endif to them. This has been tested on: Gentoo Linux with GCC 4.6.3 Windows 7 with MSVC 2010 Mac OSX 10.8 with Apple clang 4.0 (based on LLVM 3.1svn) QNX with qcc (based on GCC 4.4) A small change is needed to QtDeclarative when building for OpenGL ES 2 after applying this commit.

* Remove "All rights reserved" line from license headers.Jason McDonald2012-01-301-1/+1
| | | | | | | | | | As in the past, to avoid rewriting various autotests that contain line-number information, an extra blank line has been inserted at the end of the license text to ensure that this commit does not change the total number of lines in the license header.

| | | | | | | | | | These defines were there to aid in the commercial licensing scheme we used long ago, and are no longer needed. Keep a QT_MODULE(x) define so other modules continue compiling. Change-Id: I8fd76cd5270df8f14aee746b6cf32ebf7c23fec7 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>

| | | | | | | | | | | | | This takes out the dependency to the header files of OpenGl. The ifdef QT_NO_OPENGL in the opengl headers are needed, as qmake adds depends in the makefiles for all GUI headers.
