Identifying the window as the basis of a style – PB Docs 2019

In order for InfoMaker to recognize that a window in a library
serves as the basis for a form style, you must specify a comment for the
window that starts with the text Style:

The text that follows Style: is the text that displays below the
icon for the form style in the New Form dialog box in InfoMaker.

For example, if you save a w_pbstyle_freeform window with the
comment Style: Maintain corporate data in a style library, InfoMaker
users see this when they create a new form:

You can specify the comment either when first saving the window or
in the Library painter.
