multiple desktops

[Sergey Krivov <krivov yahoo com>]

Hello,

I wrote a simple python scripts which changes Desktop
folder when current workspace is changed. The script
basically simlinks the Desktop folder to different
folders. However, each time to make the changes
visible i have to reload Desktop by hitting Ctrl+R. Is
there any way to invoke this from within a python
script, i.e., via dbus?

Thanks

Separate desktop for each workspace:
Hit Ctrl-R to refresh desktop, each time when switched to new workspace.
If someone knows, how to force Nautilus to reload the page, please let me know.
Desktops are changing by simliking the ~\Desktop directory to ~/.desktops/Desktop0,
~/.desktops/Desktop1, etc. If no corresponding ~/.desktops/Desktopx is present,
Desktop0 is used. To add new desktop for particular workspace create the directory
.desktops/Desktopxx, where xx is the number of the workspace.
