Re: FVWM: letting fvwm do something in the background

[Klaus Umbach]

Thank you all, for helping me.

You can see the result at
http://www.stud.uni-karlsruhe.de/~ugk8/current-screenshot.jpg

It really is beautiful :-)

And here are the final(?) functions:

DestroyFunc Thumbnail
AddToFunc Thumbnail
+ I Raise
+ I Piperead "xwd -silent -id $[w.id] > $[HOME]/.fvwm/icon.tmp.$[w.id].xwd"
+ I Iconify
+ I Exec nice -19 convert -resize 64x54 -frame 1x1 -mattecolor black -quality 0 
xwd:$[HOME]/.fvwm/icon.tmp.$[w.id].xwd png:$[HOME]/.fvwm/icon.tmp.$[w.id].png; 
FvwmCommand 'WindowId $[w.id] WindowStyle IconOverride, Icon 
$[HOME]/.fvwm/icon.tmp.$[w.id].png, StaysOnBottom'

DestroyFunc DeThumbnail
AddToFunc DeThumbnail
+ I DestroyWindowStyle
+ I Exec rm -f $HOME/.fvwm/icon.tmp.$[w.id].*
+ I deiconify-and-focus


Best regards
        Klaus

5) People say Linux is ugly. How does that make you feel?
