Right, that's what I would expect. Cocoa doesn't distinguish between "can't drop" and "can drop" by changing the cursor. You might consider this a bug, in which case you should file an enhancement request. In the meantime, if the conditions under which users are permitted to drop things are complex or obscure, you might want to use the method I described before. Or you can use the same technique to put a little "no" icon next to the cursor, but I imagine it would take a bit of work to deduce where to put the icon so as to avoid the cursor image. You can't hardcode it in case the cursor has a custom image. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
