Quick reports and Custom Previewer -- How?

Hi all,

I have been trying to create a previewer that will allow filtering using
Infopower's twwfilterdialog.  I guess I will need to add a menu to the
previewer.  The documentation with QR 2.0d is extremely sparse on the
subject of custom previewers.  Can someone give me some advice/code
samples?

TIA
