NXWidgets is a graphical user interface package for the NuttX RTOS. It integrates seamlessly with the NuttX NX graphics subsystem in order to provide graphic objects, or "widgets". It is written entirely in C++ using only selected "embedded friendly" C++ constructs which are fully supported under NuttX. No additional C++ support libraries are required. It is tailored for use with MCUs in embedded applications. It is ideally suited for the mid-to-upper range of most MCU families. It will work on high-end frame buffer devices as well as on LCDs connected via serial or parallel ports to a small MCU. It 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. It supports a special widget called CKeypad which provides keyboard input via an on-screen keypad which can be operated via a mouse or touchscreen inputs. Some of the graphic objects supported by NXWidgets include labels, buttons, text boxes, button arrays, check boxes, cycle buttons, images, sliders, scrollable list boxes, and progress bars.
Redstart Graphic is an advanced graphics package inspired by the Java world. It is built using the Gd Extension, which is supported by all servers by default. It provides an extensible and clean OOP interface to deal with all kinds of graphics and advanced and basic filters and actions (crop,rotate, etc.)
ArtTk is a graphic library based on Java/Swing offering an open development toolkit intended specifically for scientific and technical applications. It provides a set of widgets and functional modules a set of support modules (helpers) permitting dynamic definition of menus and tool bars from simple XML configured files, and supporting tooltips, icons, action commands, etc.; a very adaptable generic desktop, facilitating the assembly of Swing components in a specialized GUI; an extended Grid layout to simplify the development of advanced scientific applications; and a set of scientific and technical widgets, such as a dynamic memory footprint monitor, simple key-values based fields editors, a generic color gradient editor, etc.
