remove-outline-item-value

Arguments: outline item-value &key no-redisplay

Deletes the outline-item whose value is item-value from outline. (If multiple items have the indicated value, then only the first is deleted.) If the deleted item has any descendent items, they are deleted as well.

If no-redisplay is true, then the changed part of the outline is not redrawn automatically as usual. This may be useful for efficiency if multiple items are being deleted, where remove-outline-item-value can be called several times with no-redisplay specified as true, and then invalidate called a single time on the outline widget to redraw it once only.
