One of the arguments to TPrintPreview.PaintRichText is a PInteger (pointer to integer).

Why a pointer and not just pass as a var? With overloading, you could have a version of the method that did not have that argument, and would pass its own (dummy) integer to the main method.

Cheers

It's quite simple! The component should be compatible with Delphi 3 and this version of the compoiler does not have procedure overloading, and also default parameter's value.
