I am extremely happy to announce that Qt 5.4 Beta is now available for download. There are a lot of new and interesting things in Qt 5.4 and I will try to summarize the most important highlights in this blog post.
Qt 5.4 brings capability to dynamically select during the application startup whether to use ANGLE or OpenGL on Windows. It is possible to use either opengl32.dll or ANGLE’s OpenGL ES 2.0 implementation in Qt applications without the need for two separate builds of the binaries. This significantly simplifies the task of creating Qt Quick applications for Windows PCs. Dynamic GL switching is not yet enabled in the prebuilt Qt 5.4 Beta binaries. In addition to these, there is a large number of smaller improvements and bug fixes for the Windows port in Qt 5.4.
QOpenGLContext is now able to adopt existing native contexts (EGL, GLX, …). This allows interoperability between Qt and other frameworks, such as game engines.
