Hi all,

i am implementing a cell renderer for a JTree which displays a set of nodes.
The nodes in turn represent local or remote (ftp, http, etc) files.
in order to check whether or not each file is reachable or not i use
an url connection. since this operation may be very time consuming
(when rendering lots of nodes) i use a SwingWorker3 which does
this asynchronously. the color of the nodes label will be changed then
according to the connection state of the checked file (red = not reachable,
green = ok)

everything is perfect except the fact, that changing the label color
does not work. the 'setForeground' method is called, but nothing
happens although the swing worker is running in the swing GUI thread.

does somebody has an explanation for this?
thanks for any hint :o)

BTW: i recognized that even animated GIFs do not work, when
being used to render (a part ) of a tree node ...

cheers,
chris
