-=========
-
-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).
