yes, wallpapers are provided as plugins. currently we have:

* image
* color

we also have some new ones lined up:

* mandelbrot
* virus

you can get a list using Wallpaper::listWAllaperInfo.=20

the mode in setWallpaper is dependent on the plugin; for instance, the imag=
e=20
plugin provides both SingleImage and Slideshow, as seen in the .desktop fil=
e=20
for it:

Actions=3DSingleImage;Slideshow;

you can also get this programmaticaly via the wallpaper info.

as for setting the default wallpaper, there are a few  ways of doing it. on=
e=20
is to provide a stock configuration for Image; another is to set the defaul=
t=20
wallpaper for the Plasma::Theme, but putting this in the metadata.desktop f=
or=20
the theme:

[Wallpaper]
defaultWallpaperTheme=3DthemeOrFilePath

there are also some other customizations you can make in there, including=20
defaultWallpaperSuffix, defaultWallpaperWidth, defaultHeight though you=20
shouldn't generally require those.

you certainly can. you can also provide your own wallpaper plugin, or you c=
an=20
skip wallpapers and provide a Containment plugin that just does the backgro=
und=20
painting itself.

if you want an image, the easiest is to use the image wallpaper with a=20
customized theme. iirc, you're putting together a stock embedded type syste=
m=20
so you could just as well provide a default plasma-desktop-appletsrc that h=
as=20
this information in it and then there's no need to write any code or do=20
anything else.

e.g. if i were you i'd grab the blankdesktop Containment plugin that is in=
=20
trunk/playground/base/plasma/containments/blankdesktop/ and put something l=
ike=20
this in the plasma-desktop-appletsrc:

[$i]
[Containments][1]
plugin=3Dblankdesktop
screen=3D0
wallpaperplugin=3Dimage
wallpaperpluginmode=3DSingleImage

[Containments][1][Wallpaper][image]
wallpaper=3D/usr/share/wallpapers/mywallpaper.jpg


that would give you a plasma desktop with nothing on the desktop layer but=
=20
mywallpaper.jpg, no panel and everything locked down (the [$i] thing at the=
=20
top)
