Hi, this is an undocumented method called internally inside TRichView.Format

or in some other cases.

The parameters used in that example are the same that used internally when

TRichView window width is changed, or by TRVRuler (included in

RichViewActions) when it changes margins.

With these parameters the caret position is retained, so you do not need to

use SetSelectionBounds or other functions to store it.

RVLinear.pas (included in the registered version, or can be downloded:

http://www.trichview.com/support/files/rvlinear.zip) allows working with

RichEdit-like selection coordinates - SelStart and SelLength.
