Progress 4GL Reference

CENTERED attribute

Indicates whether Progress automatically centers the frame in a window.

Data type: LOGICAL

Access: Readable/Writeable

Applies to: FRAME widget

The default value for this attribute is FALSE. When you set this attribute from FALSE to TRUE, the values of the COLUMN, ROW, X, and Y attributes for the frame change to reflect the new location of the frame. Setting the CENTERED attribute from TRUE to FALSE has no meaning and results in an error message.
