Graphics / nxwidgets NXWidgets

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 subsystem in order to provide graphic objects, or widgets, in the NX Graphics Subsystem

Some of the features of NXWidgets include:

  • Conservative C++

    NXWidgets is 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.

  • NX Integration

    NXWidgets integrate seamlessly with the NX graphics system. Think of the X server under Linux – the NX graphics system is like a tiny X server that provides windowing under NuttX. By adding NXWidgets, you can support graphics objects like buttons and text boxes in the NX windows and toolbars.

  • Small Footprint

    NXWidgets is 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.

  • Output Devices

    NXWidgets will work on the high-end frame buffer devices as well as on LCDs connected via serial or parallel ports to a small MCU.

  • 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 on very special widget called CKeypad that will provide keyboard input via an on-screen keypad that can be operated via mouse or touchscreen inputs.

  • 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.

Note: Many of the fundamental classed in NxWidgets derive from the Antony Dzeryn's Woopsi project: http://woopsi.org/ which also has a BSD style license. See the COPYING file for details.

Directory Structure

  • Kconfig

    This is a Kconfig file that should be provided at apps/NxWidgets/Kconfig. When copied to that location, it will be used by the NuttX configuration systems to configure settings for NxWidgets and NxWM

  • nxwidgets

    The source code, header files, and build environment for NxWidgets is provided in this directory.

  • UnitTests

    Provides a collection of unit-level tests for many of the individual widgets provided by nxwidgets.
