Hi Greg,
what you are looking for is itemdelete. You can pass it either an integer canvas handle or a canvas item object. There is also the clear method which removes all items from a canvas. Though usually I try to reuse canvas items by re- configure -ing.

Good morning and Happy New Year, all.
I have trolled through ltk.lisp in an attempt to discover how to erase things .. lines, rectangles, ovals .. drawn by create-line etc..
I was looking for things like erase-line or delete-rectangle, but could not find anything like this. The closest I came to discovering this sort of functionality was the destroy facility, which seems to destroy widgets. In drawing a shape, however, I may do not usually create it explicitly as a widget with an associated symbol to feed to destroy; must I do this under ltk ?
More than likely I have simply missed something (sigh).
Thanks in advance for any help and advice.
Cheers /Greg Bennett
