| <h1>NxWidgets<a class="headerlink" href="#nxwidgets" title="Permalink to this headline">¶</a></h1> |
| <p>In order to better support NuttX based platforms, a special graphical |
| userinterface has been created called NXWidgets. NXWidgets is written in |
| C++ and integrates seamlessly with the NuttX <a class="reference external" href="NXGraphicsSubsystem.html">NX graphics |
| subsystem</a> in order to provide graphic |
| objects, or “widgets,” in the NX Graphics Subsystem</p> |
| <p>Some of the features of NXWidgets include:</p> |
| <ul class="simple"> |
| <li><p><strong>Conservative C++</strong>. 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.</p></li> |
| <li><p><strong>NX Integration</strong>. NXWidgets integrate seamlessly with the <a class="reference external" href="NXGraphicsSubsystem.html">NX |
| graphics subsystem</a>. 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.</p></li> |
| <li><p><strong>Small Footprint</strong>. 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 40K of |
| FLASH and maybe 4K of SRAM.</p></li> |
| <li><p><strong>Output Devices</strong>. 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.</p></li> |
| <li><p><strong>Input Devices</strong>. 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.</p></li> |
| <li><p><strong>Many Graphic Objects</strong>. 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.</p></li> |
| <li><p><strong>DOxygen Documentation</strong> DOxygen documentation is available.</p></li> |
| </ul> |
| <p>Note: Many of the fundamental classed in NxWidgets derive from the |
| Antony Dzeryn’s “Woopsi” project: <a class="reference external" href="http://woopsi.org/">http://woopsi.org/</a> which also has a |
| BSD style license. See the COPYING file for details.</p> |

| <p>NXWidgets supports building HTML documentation via Doxygen. We should |
| integrate this into the Sphinx documentation build.</p> |
