Hi!
Acording to the API docs on java.awt.Toolkit (which ImageIcon uses to load
an image from a filename) the format of the image can either be GIF, JPEG or
PNG. That is probably your problem, since you're trying to load
ICO-files....remember that the DefaultTreeCellRenderer is in fact a JLabel
and depending on the various flags to getTreeCellRendererComponent (ie. leaf
etc.) the renderer will choose the right image and set it with setIcon(). I
may be wrong but it works for me with gifs as foldericons - I think the
naming is a little missleading though...
Sincerely yours,
Pierre Jakobsen
