It's my first posting here, so hello to everybody!

My Question: In GWT 2.3.0 I use custom icons in a map as markers. I
would love to change the icon which is currently selected. This Icon
should be similar to the original one (i.e. somehow highlighted). I
thought about different ideas which all are somehow difficult for me
to realize:

1. As the icons are (and have to be) stored in a blobdatastore I was
thinking about painting a second Icon and storing it in the same
blobdatastore. Unfortunately I did not find a way to draw in an
existing blobimage (on server side).
2. Changing the style of the icon (i.e. adding a colored border).
Unfortunately neither the icon nor the marker have a "setstyle"
method. Is the uibinder a possiblel way to do that? I see a problem in
changing the style of only the selected marker/icon.
3. Repainting the icon on client side. As far as I could find out this
won't be possible for all browsers.

Do you have any hints for me?
