Name

dumper::relativeparent

Synopsis

          relativeparent target \
             dots

Description

Provides a relative addressing scheme to target using multiple (recursive) calls to winfo parent.

NOTE : This code should not being used at all. target isn't a child of base, the common ancestor is searched for base & target (using winfo parent) and then returned to the caller. NOTE : This code does indeed work! result contains subsequent calls to winfo parent ... which will then being used on base. Example:

[winfo parent [winfo parent [winfo parent $base]]]

--Still curious, though!

Added »target«, to allow cross-examination, needed for Jeszra.
