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 =================== 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 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 true 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 task's 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. You should be able to select the NX icon in the start menu and create as many NSH sessions in windows as you want. (keybard input still comes through serial).
