Thanks for taking a look and for the comments, Guillaume. It might be nice to do as you suggest and move to QFontDialog. Whenever we can rely on Qt it seems like that is the way to go. The preview widget contained in that dialog is especially nice. I think what I'll do for now is just open an enhancement request and post our ideas there. I do not want to undertake such a project at this time. Scott
