is an abstract service for specialized FormControlModels which are data aware and thus can be bound to a data source.
The connection between a data-aware control model and a form whose data the control should display is made by parentship relations. The parent of a data-aware control model (see com::sun::star::container::XChild, inherited via the FormControlModel and FormComponent services) has always to be a com::sun::star::form::component::DataForm.
|
optional |
makes it possible to transfer the data of the model to the connected data field.
This interface is optional, if a component doesn't support it, it has to forward the changes of its value to the field it is connected to immediately (means whenever a user interaction changes it's content).
interface com::sun::star::form::XLoadListener |
must be implemented in order to recognize when the containing form of the model connects to its data source (loads its data).
After loading the form, the model may bind to its related field source.
This interface will seldom be used directly from outside.
interface com::sun::star::form::XReset |
Each DataAwareControlModel should be resettable for setting default values.
In the context of a control model which is data-aware, the semantics of default value (see XReset) is as follows:
If (and only if) the control is valid bound to a column of its com::sun::star::form::component::DataForm, and the form is not positioned on a new record (see com::sun::star::sdb::RowSet::IsNew), then XReset::reset() does not reset the model's value to its default value, but uses the underlying column value.
In all other cases, the model is reset to the default value as specified by the respective property.
For an example, have a look at the com::sun::star::form::component::TextField. It inherits the com::sun::star::awt::UnoControlEditModel::Text property from the underlying service, and additionally specifies the com::sun::star::form::component::TextField::DefaultText.
In the context of a com::sun::star::form::component::DataForm, controls are automatically reset when one of the following applies
|
propertyreadonly |
references to the cursor field to which the control is bound.
Applies only if the form the control model belongs to is loaded and the control is valid bound. The referenced field supports the com::sun::star::sdb::Column service.
|
property |
specifies the name of the bound database field.
This property makes sense in the context of the control model only. Normally, a control model is a child of a com::sun::star::form::component::DataForm, which is bound to a higher level object such as a table or query - more general, a result set.
This member here describes the column of this result set which the control should act for.
Not every control model can be bound to every database column. Usually, super services of the DataAwareControlModel restrict the column types they can be used with.
|
optionalproperty |
determines whether or not input into this field is required, when it is actually bound to a database field.
If this property is set to FALSE
, then the form runtime will not check the control/model for NULL
values before submitting data to the database. Usually, if a control model is bound to a database field which cannot be NULL
, and the model itself does not have a value, then the database update is prevented, showing an error message to the user. To disable this behavior on a per-control basis, use the InputRequired
property.
|
property |
references to a control model within the same document which should be used as a label.
Any user interface action which needs to refer to the control is assumed to use this property.
A very common design method for forms is to group a data aware control with a label control, with the latter describing the content of the former. For instance, you may have a com::sun::star::form::component::TextField, which is bound to the e-mail column of your data source. Then you will probably add a com::sun::star::form::component::FixedText whose label is "E-Mail", and associate it with the TextField by setting it as LabelControl.
Now if you imagine a component offering data search in a form, this component will examine the LabelControl property, find the com::sun::star::form::component::FixedText, examine it's label, and use this label to refer to the com::sun::star::form::component::TextField.
When setting the property, a number of constraints apply:
Additionally, the support of a special service, indicating that the model is of the right type, is required. Which kind of service is in the request depends on the type of the control model.
For instance, text fields (com::sun::star::form::component::TextField) can be labeled by label controls only (com::sun::star::form::component::FixedText), and radio buttons (com::sun::star::form::component::RadioButton) can be labeled by group boxes (com::sun::star::form::component::GroupBox) only.
