Package: TkPatch
use lib::TkPatch;
The file TkPatch.pm is located in the subdirectory './lib'
This package contains all function that extend some functionality in the original Perl/Tk distribution files. They do not create new derived or congregate widgets, they just override single functions in the exiting widgets.
These functions are not called form somewhere inside of e:doc directly, they override the ones that already exist.
They are placed in this seperate file because -if this functionality gets added to the original Perl/Tk distribution- they might easily be deleted from here.
Coding: this is an open end package, so no status percentage can be mentioned here
Documentation: up-do-date
Until the original Tk::Text widget is able to scroll line-by-line when the content is wrapped, I add this functionality here.
