/*! \mainpage NXWidgets Documentation * * In order to better support NuttX based platforms, a special graphical user * interface has been created called NXWidgets. NXWidgets is written in C++ * and integrates seamlessly with the NuttX NX graphics subystem in order to * provide graphic objects, or "widgets", in the * NX Graphics Subsystem. * * \section feature Features * * \subsection conservative_cxx Conservative C++ * * Written entirely in C++ but using only selected "embedded * friendly" C++ constructs that are fully supported under NuttX. No * additional C++ support libraries are required. * * \subsection nx_integration NX Integration * * Integrates seamlessly with the NX graphics subsytem. Think of the X * server under Linux... the NX graphics subsystem is like a tiny X server * that provides windowing under NuttX. By adding NXWidgets, you can * support graphic objects like buttons and text boxes in the NX windows * and toolbars. * * \subsection small_footprint Small Footprint * * Tailored for use MCUs in embedded applications. It is ideally suited for * mid- and upper-range of most MCU families. A complete NXWidgets is * possible in as little as 40Kb of FLASH and maybe 4Kb of SRAM. * * \subsection output_devices Output Devices * * NXWidgets will work on the high-end fram buffer devices as well as on * LCDs connected via serial or parallel port to a small MCU. * * \subsection input_devices Input Devices * * NXWidgets will accept position and selection inputs from a mouse or a * touchscreen. It will also support character input from a keyboard such * as a USB keyboard. NXWidgets supports a very special widget called * CKeypad that will provide keyboard input via on-screen keypad that can * be operated via mouse or touchscreen inputs. * * \subsection many_graphic_objects Many Graphic Objects\ * * Some of the graphic objects supported by NXWidgets include labels, * buttons, text boxes, button arrays, check boxes, cycle buttons, images, * sliders, scrollable list boxes, progress bars, and more. */
