Hi,

I'm currently experimenting on getting swt to work on the nokia nk770. 
I'm using mika jvm, which runs fine on the nokia. I managed to compile 
swt and I'm able to run the example swt applications using mika.

I'm still facing some issues: Once your swt window is gone (switched to 
background), I don't find a way to make it visible again. We're indeed 
missing to Window Manager.
The way I compile swt is still a bit of hack. The regular swt build 
script is not really intended to do cross compilation, therefore most of 
the auto detection had to be removed. Second issues is to find a good 
stand alone arm-Linux-gcc tool chain for the nk770. So for now I'm kind 
of stuck.
  Any help would be appreciated...

  kind regards,
