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. Use remove-outline-item instead to avoid this ambiguity.) 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.
