# Graphics / `nxwm` NxWM
|
|
|
|
This directory holds a tiny desktop for small embedded devices with a
|
|
touchscreen,. NxWM. NxWM is true multiple window manager but only one window is
|
|
displayed at a time. This simplification helps performance on LCD based products
|
|
(in the same way that a tiled window manager helps) and also makes the best use
|
|
of small displays. It is awkward from a human factors point-of-view trying to
|
|
manage multiple windows on a small display.
|
|
|
|
The window manager consists of a task bar with icons representing the running
|
|
tasks. If you touch the task's icon, it comes to the top. Each window has a
|
|
toolbar with (1) a title, (2) a minimize button, and (3) a stop application
|
|
button using the standard icons for these things.
|
|
|
|
There is always a start window that is available in the task bar. When you touch
|
|
the start window icon, it brings up the start window containing icons
|
|
representing all of the available applications. If you touch an icon in the
|
|
start window, it will be started and added to the task bar.
|
|
|
|
There is a base class that defines an add-on application and an interface that
|
|
supports incorporation of new application. The only application that is provided
|
|
is NxTerm. This is an NSH session running in a window. You should be able to
|
|
select the NX icon in the start menu and create as many NSH sessions in windows
|
|
as you want. (keybard input still comes through serial).
|
|
|
|
Note 1: NwWM requires `NuttX-7.19` or above to work with the current
|
|
`NxWidgets-1.18` release.
