| Note: | The primary purpose of this class is to mix DEO capabilities into a ComboForm. This supports the ability to fill a combo list with valid database values. Its subclass dbDataComboForm extends this class by allowing it to support separate values for display and database. The dbDataComboForm is also considered to be an intermediate class. Its subclass dbComboForm supports all these abilities and adds data-dictionary support. The dbComboForm should be used for instantiation. It supports data-value combo lists, description-value combo lists, and can be used with and without data dictionaries. |
Please refer to the dbForm class concerning data entry object (DEO) form messages and behaviors. Refer to the ComboForm class for information regarding combo-form messages and behaviors.
