Other Design Considerations

The radio buttons take up a lot of screen space in the Snapshot GUI. CDE provides a widget called a DtComboBox that takes up less screen space and provides the same functionality. The Snap Type and Snap Delay radio buttons are replaced by DtComboBox widgets. The most typically used values appear as DtComboBox defaults.

You cannot use the DtComboBox widget if you are developing your application for the OpenWindows desktop. This widget is part of the CDE development environment, not the OpenWindows development environment. Even if you do have access to the ComboBox, however, you may want to retain the radio boxes, depending on issues such as ergonomics, customer needs, and consistency.
