public class PropertiesBox

extends java.awt.List

A list box allowing properties from a model to be selected and unselected. Shows all properties in a model (rdf:_n are shown as a single entry). By selecting and unselecting individual properties, the user can influence what is shown on the screen.

The list box is associated with a StatementSelector which chooses only statements whose property is selected in the box.

A NamespaceMap is used to preprocess property names before showing them on the screen. After this preprocessing, the properties are shown in alphabetical order.

Method Detail

setModel

public void setModel(Model model,
                     NamespaceMap names)
              throws RDFException

Set the model from which properties are shown. Initially, all properties are selected.

RDFException

getStatementSelector

public StatementSelector getStatementSelector()

Get the statement selector associated with this PropertiesWindow. The selector will select a statement iff its property is selected in this window.

processItemEvent

protected void processItemEvent(java.awt.event.ItemEvent e)

Dispatch an ItemEvent and call refresh().

Overrides:

processItemEvent in class java.awt.List

refresh

public void refresh()

Re-read the set of shown properties from the selections in this list box. This ensures that the StatementSelector related to this box really accepts exactly those properties selected in the list box.

This cannot be an ItemListener because the select() and deselect() methods do not generate ItemEvents. When the selection is changed through these methods, refresh() must be called for the changes to take effect.

This is relevant for the unit tests.
