Sample Code

apps/examples/nx*. 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.

• apps/examples/nx. 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.

• apps/examples/nxhello. This is intended to be simplest NX test: It simply displays the words “Hello, World!” centered on the display.

• apps/examples/nxtext. 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.

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.

Building apps/examples/nx. Testing was performed using the Linux/Cygwin-based NuttX simulator. Instructions are provided for building that simulation are provided in Appendix C of this document.
