* Extend QOpenGLFunctions with GL1 functionsLaszlo Agocs2014-03-042-98/+1286
| | | | | | | | | | | | | | | | | | This introduces the ability to indirectly invoke all common GL1-GLES2 functions via QOpenGLFunctions. The GL1 functions are not yet resolved, since this would not work anyway when linking to an OpenGL implementation directly. However this may change later but that will be a completely internal change without affecting any public APIs. Also migrate some of the opengl examples to use QOpenGLFunctions for everything. Once dynamic GL loading becomes available on some platforms, these examples should continue to function without any changes since they do not anymore invoke any OpenGL functions directly.

* Dynamic GL: remove exporting symbolsLaszlo Agocs2014-03-0415-4746/+63
| | | | | | | | | | | | | | | | | | | | | Remove the opengl proxy for now. Later it will either be moved into a separate library or replaced by a QOpenGLFunctions-based approach. This means that the -opengl dynamic configuration is not usable for the time being. The rest of the enablers remain in place. The convenience function QOpenGLFunctions::isES() is now moved to QOpenGLContext and is changed to check the renderable type. This is extremely useful since besides supporting dynamic GL it solves also the problem of GL_ARB_ES2_compatibility (i.e. it triggers the real ES path when creating an ES-compatible context with a desktop OpenGL implementation).

* QOpenGLTextureBlitter: Remove Origin location for the Target rectJørgen Lind2014-02-162-14/+12
| | | | | | | | | | | | | | | | | | | | | The Origin for Target rect was deemed a confusing concept. The current implementation would translate the target rect to the coordinate system specified. However, the order and "direction" of the vertices would always be the same. So drawing a texture in for one target rect defined in one coordinate system would paint the texture the same way as it would when a texture was drawn for a target rect drawn in the "opposite" coordinate system. The point with this was that if you wanted to "flip" the texture you would specify that with the source coordinate system. However, this approach breaks on different levels, such as QRect has functions which expects a top left coordinate system (ie. top() and bottom()). In the end Qt uses a top left coordinate system, hence QWindow specifies a top left coordinate system, and hence the api becomes easier if it is not possible to define the coordinate system of the target viewport.

* Dynamic GL switch on WindowsLaszlo Agocs2014-02-1419-487/+5271
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch introduces a new build configuration on Windows which can be requested by passing -opengl dynamic to configure. Platforms other than Windows (including WinRT) are not affected. The existing Angle and desktop configurations are not affected. These continue to function as before and Angle remains the default. In the future, when all modules have added support for the dynamic path, as described below, the default configuration could be changed to be the dynamic one. This would allow providing a single set of binaries in the official builds instead of the current two. When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are never defined. Instead, the code path that has traditionally been desktop GL only becomes the dynamic path that has to do runtime checks. Qt modules and applications are not linked to opengl32.dll or libegl/glesv2.dll in this case. Instead, QtGui exports all necessary egl/egl/gl functions which will, under the hood, forward all requests to a dynamically loaded EGL/WGL/GL implementation. Porting guide (better said, changes needed to prepare your code to work with dynamic GL builds when the fallback to Angle is utilized): 1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to differentiate between desktop and ES where needed. Keep in mind that it is the desktop GL header (plus qopenglext.h) that is included, not the GLES one. QtGui's proxy will handle some differences, for example calling glClearDepth will route to glClearDepthf when needed. The built-in eglGetProcAddress is able to retrieve pointers for standard GLES2 functions too so code resolving OpenGL 2 functions will function in any case. 2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds, but never "angle" or "opengles2". 3. The preprocessor define QT_OPENGL_DYNAMIC is also available in dynamic builds. The usage of this is strongly discouraged and should not be needed anywhere except for QtGui and the platform plugin. 4. Code in need of the library handle can use QOpenGLFunctions::platformGLHandle(). The decision on which library to load is currently based on a simple test that creates a dummy window/context and tries to resolve an OpenGL 2 function. If this fails, it goes for Angle. This seems to work well on Win7 PCs for example that do not have proper graphics drivers providing OpenGL installed but are D3D9 capable using the default drivers. Setting QT_OPENGL to desktop or angle skips the test and forces usage of the given GL. There are also two new application attributes that could be used for the same purpose. If Angle is requested but the libraries are not present, desktop is tried. If desktop is requested, or if angle is requested but nothing works, the EGL/WGL functions will still be callable but will return 0. This conveniently means that eglInitialize() and such will report a failure. Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will tell which implementation is chosen. The textures example application is ported to OpenGL 2, the GL 1 code path is removed. [ChangeLog][QtGui] Qt builds on Windows can now be configured for dynamic loading of the OpenGL implementation. This can be requested by passing -opengl dynamic to configure. In this mode no modules will link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will dynamically choose between desktop and Angle during the first GL/EGL/WGL call. This allows deploying applications with a single set of Qt libraries with the ability of transparently falling back to Angle in case the opengl32.dll is not suitable, due to missing graphics drivers for example.

* | Add takeTexture() to QOpenGLFramebufferObjectLaszlo Agocs2014-01-073-41/+97
|/ | | | | | | | | | | | | Add an API that allows to retrieve and detach the texture from the framebuffer object. The next bind() call will then create and attach a new texture. [ChangeLog][QtGui][QOpenGLFramebufferObject] Added takeTexture() for retrieving and detaching the texture from the framebuffer object.

* QOpenGLPixelTransferOptions: declare as shared, add move assignment operatorMarc Mutz2013-11-141-0/+10
| | | | | | | | | | | | | | A move constructor cannot be added because the class uses a smart pointer to hold its pImpl, so the move ctor would have to be out-of-line, destroying BC between C++11 and C++98 versions of Qt. Member-swap is required for Q_DECLARED_SHARED, which in turn enables efficient use of the class in Qt containers by marking it movable.
