OPENGL 2.0 CAPABLE SYSTEM DRIVERS
On other machines, where there is sufficient OpenGL support, the normal desktop OpenGL drivers will be used. Such a fallback could, for example, take place on a Windows 7 PC with no additional graphics drivers installed.
OPENGL 2.0 CAPABLE SYSTEM CODE
This fallback will be completely transparent to the application, and will allow Qt Quick or other OpenGL code to function by translating to Direct3D. When a given environment fails to provide a proper OpenGL 2.0 implementation, it will fall back automatically to ANGLE. This configuration is the most flexible because no dependencies or assumptions are hardcoded about the OpenGL implementation during build time. Note: Combining -opengl dynamic with -static is also possible, but be aware that ANGLE will not be statically linked into the applications in this case, it will still be built as a shared library. It is strongly recommended to use it also in custom builds, especially for Qt binaries that are deployed alongside applications. Note: As of Qt 5.5 this is the configuration used by the official, pre-built binary packages of Qt. To use OpenGL, pass the command line options -opengl desktop to the configure script. If you installed additional OpenGL drivers from your hardware vendor, then you may want to consider using this version of OpenGL instead of ANGLE. To use a custom version of ANGLE, set the ANGLE_DIR environment variable to point to the ANGLE source tree before building Qt. Possible values are d3d11, d3d9 and warp. For these cases, the environment variable QT_ANGLE_PLATFORM (introduced in Qt 5.4) can be used to control the render backend. However, some graphics cards may not fully support it. ANGLE requires that the DirectX SDK is installed when building Qt.ĪNGLE chooses the render backend depending on availability. ANGLE implements the OpenGL ES 2.0 API on top of DirectX 11 or DirectX 9. Qt includes a version of the ANGLE project which is included from the Windows Qt installers.
OPENGL 2.0 CAPABLE SYSTEM DRIVER
The default driver from Windows is OpenGL 1.1. To explicitly enable the use of ICU in Qt Core, pass -icu to configure:įor Qt Quick 2 to work, a graphics driver that provides OpenGL 2.1 or higher is required. QCollator::setNumericMode() does work consistently on all Windows versions.QLocale::toUpper(), QLocale::toLower() always use case conversion rules specific to the locale.Extended set of text codecs (see QTextCodec).Behavior matches other platforms more closely.Letting Qt Core utilize the ICU libraries however has following advantages: This reduces the size of a self-contained application package considerably. ICUįrom Qt 5.3 and onwards, configure does not link Qt Core against ICU libraries anymore by default. See Secure Sockets Layer (SSL) Classes for instructions on building Qt with SSL support.

Support for Secure Sockets Layer (SSL) communication is provided by the OpenSSL Toolkit, which must be obtained separately.
