Interface Builder actually makes a couple of windows to do that. One
wide window for the horizontal part of the line, and another tall and
thin window for the vertical part. The positions of the windows change
as your mouse moves, and they have simple views inside that draw
basically just blue over their entire contents.
Hope this helps,

How do Interface Builder and Quartz Composer draw the blue line

from object to object?
I have been looking through the APIs, but I can't find anything that
looks
right.
I thought of just drawing my own line on a custom view (shouldn't be
that
hard), but interface builder manages to do it between objects that
aren't
connected by ANY view, and I am not sure how to do that.
I am trying to build an HTML GUI editor.
Thanks in advance!
