<h1>NXWidgets</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 NX graphics subsystem in order to provide graphic objects, or "widgets," in the NX Graphics Subsystem
|
|
</p>
|
|
<p>
|
|
Some of the features of NXWidgets include:
|
|
</p>
|
|
<ul>
|
|
<li><b>Conservative C++</b>.
|
|
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.
|
|
</li>
|
|
<li><b>NX Integration</b>.
|
|
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.
|
|
</li>
|
|
<li><b>Small Footprint</b>.
|
|
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.
|
|
</li>
|
|
<li><b>Output Devices</b>.
|
|
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.
|
|
</li>
|
|
<li><b>Input Devices</b>.
|
|
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.
|
|
</li>
|
|
<li><b>Many Graphic Objects</b>.
|
|
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.
|
|
</li>
|
|
<li><b>DOxygen Documentation</ba>
|
|
DOxygen documentation is available.
|
|
</li>
|
|
</ul>
|
|
<p>
|
|
Note: Many of the fundamental classed in NxWidgets derive from the Antony
