public abstract class EntityEditPanel
extends JPanel

An abstract UI component for editing a single entity, based on a SwingEntityEditModel.

The edit model is a thin context-carrier; the panel's working surface is the SwingEntityEditor (accessible via editor()) — it holds the edited values, the validation state and the insert/update/delete tasks. Subclasses implement initializeUI() to create and lay out the input components.

class CustomerEditPanel extends EntityEditPanel {

	CustomerEditPanel(SwingEntityEditModel editModel) {
		super(editModel);
	}

	@Override
	protected void initializeUI() {
		create().textField(Customer.FIRSTNAME);
		create().textField(Customer.LASTNAME);

		setLayout(gridLayout(2, 1));

		addInputPanel(Customer.FIRSTNAME);
		addInputPanel(Customer.LASTNAME);
	}
}

Parameters:

model - the EntityEditModel instance to base this EntityEditPanel on

config - provides access to the panel configuration

Method Details

model

public final SwingEntityEditModel model()

Returns:

the edit model this panel is based on

selectInputComponent

public final void selectInputComponent()

Displays a dialog allowing the user to select an input component which should receive the keyboard focus.

If only one input component is available, that component is selected automatically without displaying a dialog.

If no component is available, f.ex. when the panel is not visible or none of the available components is focusable, this method does nothing.

Input components can be excluded from this selection using EntityEditPanel.Config.excludeFromSelection(Collection).

See Also:

• EntityEditPanel.InputFocus.request(Attribute)

Performs insert on the active entity.

If insert confirmation is enabled, confirmation is requested first using the EntityEditPanel.Confirmer specified via EntityEditPanel.Config.insertConfirmer(Confirmer).

update

public final void update()
                  throws EntityValidationException

Throws:

EntityValidationException - in case of validation failure

IllegalStateException - in case the active entity is unmodified (thrown synchronously)

See Also:

• EntityEditPanel.Config.confirmUpdate(boolean)

onException

protected void onException(Exception exception)

Propagates the exception to onValidationException(EntityValidationException) or onReferentialIntegrityException(ReferentialIntegrityException) depending on type, otherwise forwards to the super implementation.

Parameters:

exception - the exception to handle

onReferentialIntegrityException

protected void onReferentialIntegrityException(ReferentialIntegrityException exception)

Called when a ReferentialIntegrityException occurs.

onValidationException

protected void onValidationException(EntityValidationException exception)

Displays the exception message after which the first invalid component receives the focus. In multi-slot detail editor configurations the source slot is identified by walking each editor's per-attribute valid state — the focused component is the first invalid one in focus traversal order, not just the first registered for the attribute.

Parameters:

exception - the validation exception

displayException

protected final void displayException(Exception exception)

	addInputPanel(Employee.FIRSTNAME);
	addInputPanel(Employee.LASTNAME);
}

configureControls

protected final void configureControls(Consumer<Controls.Layout> controlsConfig)

Configures the controls.

Returns:

the Value containing the control associated with controlKey

controls

protected final Controls controls()

Returns a Controls instance containing all the controls configured via configureControls(Consumer).
