Compatibility with Motif 2.1

The APIs of the DtSpinBox and DtComboBox widgets are similar to the Motif 2.1 release of XmSpinBox and XmComboBox widgets. The APIs are designed so an application can easily switch to the Motif 2.1 version of these widgets. To switch, change the Dt names for the class, types, and creation routines to Xm. For example, change all occurrences of DtSpinBox in your code to XmSpinBox. This information is supplied in case you choose to port your application to Motif 2.1, but it is not a recommendation that you do so.

The Common Desktop Environment does not guarantee strict API or binary compatibility between its widgets and the Motif 2.1 widgets.
