* Rename new QOpenGLContext APIsLaszlo Agocs2014-04-251-3/+3
| | | | | | | | | | | | | | isES() becomes isOpenGLES(). The library type enums are changed DesktopGL -> LibGL and GLES2 -> LibGLES. This removes the now unnecessary version number, the confusing "desktop" term and provides better readability. The old function/values are kept until the related qtdeclarative changes are integrated.

* Dynamic GL: remove exporting symbolsLaszlo Agocs2014-03-041-3/+3
| | | | | | | | | | | | | | | | | | | | | 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).

* Dynamic GL switch on WindowsLaszlo Agocs2014-02-141-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 devicePixelRatio metric to QPaintDevice.Morten Johan Sørvig2013-04-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously QPainter computed the devicePixelRatio based on the physical and logical dpi, and expected that the ratio between them would be either 1x or 2x. This was problematic for paint devices like printers where the physical dpi can be much higher than the logical dpi, and also for QScreen where the physical dpi would have to be defined as a multiple of the logical dpi. Add QPaintDevice::PdmDevicePixelRatio and QPaintDevice:: devicePixelRatio() getter and implement it for the QPaintDevice subclasses. Use it when calculating the highdpi scale transform in qpainter.cpp and when scaling the clip rect in qwidget.cpp. Remove physical dpi scaling for QImage, QPixmap and QOpenGLPaintDevice, reverting to the old behavior.

* Added explicit threading API to QtOpenGL.Samuel Rødal2012-11-301-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | Since QtOpenGL/QGLContext is implemented in terms of QtGui/QOpenGLContext which has stricter requirements about how it's supposed to be used, we need to apply these requirements to QGLContext as well. This change adds QGLContext::moveToThread(QThread *) and documents it as a necessity for making a context current on another thread. Also introduces QGLPixelbuffer::context() to access the QGLContext of a pixelbuffer, and made QGLWidget::context() return a non-const QGLContext, since there's no good reason why it shouldn't, and it leads to less const_cast clutter. We could have introduced a backdoor in QOpenGLContext instead, making it loosen its requirements, but that would have made it harder / impossible to fully support threaded OpenGL in all the platforms.
