Creating Data-Aware Forms¶
Using the SQL models described above, the contents of a database can be presented to other model/view components. For some applications, it is sufficient to present this data using a standard item view, such as QTableView
. However, users of record-based applications often require a form-based user interface in which data from a specific row or column in a database table is used to populate editor widgets on a form.
Such data-aware forms can be created with the QDataWidgetMapper
class, a generic model/view component that is used to map data from a model to specific widgets in a user interface.
QDataWidgetMapper
operates on a specific database table, mapping items in the table on a row-by-row or column-by-column basis. As a result, using QDataWidgetMapper
with an SQL model is as simple as using it with any other table model.
The Books example shows how information can be presented for easy access by using QDataWidgetMapper
and a set of simple input widgets.
