| <h1>Sample Code<a class="headerlink" href="#sample-code" title="Permalink to this headline">¶</a></h1> |
| <p><code class="docutils literal notranslate"><span class="pre">apps/examples/nx*</span></code>. No sample code is provided in this document. |
| However, examples can be found in the NuttX source tree at the follow |
| locations: That example code is intended to test NX. Since it is test |
| code, it is designed to exercise functionality and does not necessarily |
| represent best NX coding practices.</p> |
| <ul class="simple"> |
| <li><p><code class="docutils literal notranslate"><span class="pre">apps/examples/nx</span></code>. This is a test of windows, optionally with |
| toolbars. Two windows are created, re-sized, moved, raise lowered. |
| Simulated mouse and keyboard input is provided.</p></li> |
| <li><p><code class="docutils literal notranslate"><span class="pre">apps/examples/nxhello</span></code>. This is intended to be simplest NX test: |
| It simply displays the words “Hello, World!” centered on the display.</p></li> |
| <li><p><code class="docutils literal notranslate"><span class="pre">apps/examples/nxtext</span></code>. This illustrates how fonts may be managed |
| to provide scrolling text windows. Pop-up windows are included to |
| verify the clipping and re-drawing of the text display.</p></li> |
| </ul> |
| <p>In its current form, the NX graphics system provides a low level of |
| graphics and window support. Most of the complexity of manage redrawing |
| and handling mouse and keyboard events must be implemented by the NX |
| client code.</p> |
| <p><strong>Building</strong> <code class="docutils literal notranslate"><span class="pre">apps/examples/nx</span></code>. Testing was performed using the |
| Linux/Cygwin-based NuttX simulator. Instructions are provided for |
| building that simulation are provided in <a class="reference external" href="#testcoverage">Appendix C</a> |
| of this document.</p> |
