I need to hide several columns of text on the left side of a document under program control, i.e., narrow the view so that the horizontal scroll bar cannot bring the hidden columns into view, yet the hidden columns will still contain data. This is very like the way that TkCanvas can set a -scrollRegion. Is this possible with the TkText widget? If so, how might I do that? -- "It requires wisdom to understand wisdom: the music is nothing if the audience is deaf." - Walter Lippman
