yep. that's what i mean. but when i try this, nothing happens. (i see
that the program is grabbing pictures, but i don't see them on my
background.

does e blocks these?

well - more like it hides their output. you won't see it.

and there's no way to go around this? so that you can see the output?

if you modify the code - yes, and that means you lose:

1. root menus
2. ibar, ibox, engage, pager, clock, battery meter, start module, cpufreq and
temperature moudles - weatehr module etc. ie everything that creates a gadget
on your desktop.

basically there is no ORGANISED way to draw to the root window - it's a free
for all. if a screensaver draws to it - then it will draw OVEr anytgin e draw -
bg, gagdtes etc. e has no idea when it draws and what it draws and how much.
this is why e overlays the root window another window it uses for the desktop
to end the whole "who draws on root" war.

This may be a really silly question, but isn't there a way to make the 
overlay window transparent?

Just wondering is there a way to tell other apps to draw to this window?
Or maybe let me rephrase, is there a way that e's "root window" accepts
changing input sent from another program ? Is that even possible?
Cheers

any x progam - if they know how to find the window could in theory draw on it -
but you'd end up with the same mess/war of drawing you end up on the root
window. thisw is why e has modules - to allow extensions in an organised way
for things to share the desktop bg. 2 clients drawing to the same window is
just a very bad bad bad bad idea. there is no way for them to organise who
draws what where and when without creating a big protocol for it, thus e takes
the "well screw you - i'm the wm and my policy is that i draw on root and you
guys just can go back home and suck eggs!" :) e provides a way to extend to
allow the root to be shareed - as i said and that mechanism is modules.

so basicaly, if i want moving images (say like glmatrix or glslideshow)
as a background, i should start learning programming and write a module
for e? (how long would it take to learn c???) ;-)

thx for the interesting answers and for the good work you're doing,
rasterman!

no, just pick up a text editor and learn .edc code - the background 
files (.edj (compiled .edc)) is capable of doing all of these things...

yes. or... you could figur eout edje and make an animated desktop bg wallpaper
as it supports animation. it isnt fulyl algodithmic animation thoguh you can
partially do it, but it can do a lot. the cool bit is your edje bg will work on
any machine - any platform, anywhere, and doesnt need to be a module. it can be
previews, thumbnailed and more. :)
