Not really.

I suppose you could draw a line over the line to be erased in the
background color. Of course, if the line intersected with other
lines, you'd have breaks in the line.

If you're doing something like rubber banding, you can use Xor

Otherwise, you probably will have to just redraw the object. I find
that the redraws, even of relatively complicated free objects, is fast

I've even created pseudo-scrolled free objects which completely redraw
a page sized area full of text and Pixmap graphics that scroll fast
enough to keep up with a slider.
