ALWAYS-ON-TOP attribute

Indicates whether the window should remain on top of all windows, even windows belonging to other applications.

Data type: LOGICAL

Access: Readable/Writeable

Applies to: WINDOW widget

This attribute differs from the TOP-ONLY attribute, which indicates that the window should remain on top of all windows of the OpenEdge session. Windows that have the ALWAYS-ON-TOP attribute set are always above TOP-ONLY windows in the z-order; they are also above dialog boxes in some cases.

A window cannot have both the TOP-ONLY and ALWAYS-ON-TOP attributes set. Setting the ALWAYS-ON-TOP attribute to TRUE will set the TOP-ONLY attribute to FALSE. The default value of the ALWAYS-ON-TOP attribute is FALSE.
