feedback in tree viewers while dragging elements [message #96634]

Hi,

I have a tree viewer and I'm moving an element. I'd like to change the
cursor appearence according to the part I'm hovering over and get the NO
Cursor.

Another question is how do I completely disable moving an element in the
tree?

thanks

yoav

There may be a bug open on this already, but go ahead and open another. One
way to do this is to query the target editpart for its command, and check
canExecute(). The other way to do this is to have the target become NULL,
in which case NOT should be shown.

We are using an internal transfer class which does not currently have an
enablement check. Please open a bugzilla. We can fix this for 3.0.
