RichTextEdit control – PB Docs 2019

RichTextEdit control

A RichTextEdit control contains a document that it displays as
formatted text. It can include input fields that are linked to a
DataWindow control. When a DataWindow’s data is shared with the
RichTextEdit control, there is one instance of the document in the control
that can be displayed multiple times with different occurrences of row
data. Input fields whose names match columns in the DataWindow are filled
with data from the current row.

RichText editors

You can select from the three rich text editors supported by
Appeon PowerBuilder. The selected rich text editor will be applicable to
the RichTextEdit control, the RichText DataWindow object, and the
RichText edit style. For more information about the rich text editors,
see the section called “Rich text editors” in Application Techniques; and for feature difference of the rich
text editor, see the section called “Feature difference between TE Edit Control and TX Text
Control”
in Application Techniques.

Using with animation features

RichTextEdit controls may not paint correctly when you use
animation features.
