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 <20>embedded
|
|
|
|
|
friendly<6C> 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 <20> 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.
