See the + \l{Supported Platforms} page for more information. + + This page contains information about the Qt for INTEGRITY port. More + information about the combinations of platforms and compilers supported + by Qt can be found on the \l{Supported Platforms} page. + + Note that Qt for INTEGRITY is currently based on \l{Qt for Embedded Linux}, + which contains its own windowing system. + + Qt for INTEGRITY contains experimental screen and input drivers based on the + gh_FB Framebuffer API for graphics, a Connection-based mouse and keyboard + support. For information about these drivers, please refer to Green Hills + Software standard support. + + \tableofcontents + + \section1 Supported Versions + + Qt has been tested on INTEGRITY 10 on various PowerPC, ARM and x86 targets. + On some platforms a native graphics FrameBuffer driver is available and has + then been used for testing.
