Encapsulation of DICOM queries into a higher level abstraction that supports creation of a tree model based on the results of a query, and a graphical user interface to that model.

An abstract class {@link com.pixelmed.query.QueryInformationModel QueryInformationModel} class is supplied that encapsulates the behavior of performing a query using the supplied information and returns the results as a {@link com.pixelmed.query.QueryTreeModel QueryTreeModel}.

A concrete sub-class {@link com.pixelmed.query.StudyRootQueryInformationModel StudyRootQueryInformationModel} class can be used to perform such a query using the most commonly supported DICOM query model.

Any such query is based on a list of user-supplied DICOM attribute values used to define the matching and return keys. A {@link com.pixelmed.query.FilterPanel FilterPanel} class is supplied that provides a graphical user interface for editing the values of attributes in list.

A user interface for displaying and traversing the result of a query is supplied, {@link com.pixelmed.query.QueryTreeBrowser QueryTreeBrowser}, which may be sub-classed in an application to provide specific functionality when selecting a path in the tree, by overriding the various methods which return a {@link javax.swing.event.TreeSelectionListener TreeSelectionListener}.
