-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:

-

-o 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.

-

-o 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.

-

-o 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.

-

-o 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.

-

-o 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.

-

-o 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

-===================

-

-libnxwidgets

-

-  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 libnxwidgets.

-

-nxwm

-

-  This directory holds a tiny desktop for small embedded devices with a

-  touchscreen,. NxWM.  NxWM is truly multiple window manager but only one

-  window is displayed at a time.  This simplification helps performance on

-  LCD based products (in the same way that a tiled window manager helps)

-  and also makes the best use of small displays.  It is awkward from a

-  human factors point-of-view trying to manage multiple windows on a

-  small display.

-

-  The window manager consists of a task bar with icons representing the

-  running tasks.  If you touch the tasks icon, it comes to the top.  Each

-  window has a toolbar with (1) a title, (2) a minimize button, and (3) a

-  stop application button using the standard icons for these things.

-

-  There is always a start window that is available in the task bar.  When

-  you touch the start window icon, it brings up the start window containing

-  icons representing all of the available applications.  If you touch an

-  icon in the start window, it will be started and added to the task bar.

-

-  There is a base class that defines an add-on application and an

-  interface that supports incorporation of new application.  The only

-  application that is provided is NxConsole.  This is an  NSH session

-  running in a window.  I should be able to select the NX icon in the start

-  menu and create as many NSH sessions in windows as I want. (keybard input

-  still comes through serial).
