Now you create a new DataWindow object and display it in the
DataWindow painter. Like other painters, the DataWindow painter has an
assortment of views that you can open simultaneously.
About the Design view of the DataWindow painter
The Design view in the DataWindow painter is similar to the Layout
view in other painters. You can open only one Design view at a
time.
The Design view is divided into four areas called bands: header,
detail, summary, and footer. You can modify the contents of these bands.
For example, you can change their sizes, add objects (controls, text,
lines, boxes, or ovals), and change colors and fonts.
In the Preview view of the DataWindow painter, you can see how the
object looks in an application at runtime, complete with table
data.
