ptolemy.actor.gui.PtolemyQuery

This class is a query dialog box with various entries for setting the values of Ptolemy II attributes that implement the Settable interface and have visibility FULL. One or more entries are associated with an attribute so that if the entry is changed, the attribute value is updated, and if the attribute value changes, the entry is updated. To change an attribute, this class queues a change request with a particular object called the change handler. The change handler is specified as a constructor argument.

It is important to note that it may take some time before the value of a attribute is actually changed, since it is up to the change handler to decide when change requests are processed. The change handler will typically delegate change requests to the Manager, although this is not necessarily the case.

To use this class, add an entry to the query using addStyledEntry(). @author Brian K. Vogel and Edward A. Lee @version $Id: PtolemyQuery.java,v 1.130 2007/12/06 21:56:45 cxh Exp $ @since Ptolemy II 0.4 @Pt.ProposedRating Yellow (eal) @Pt.AcceptedRating Yellow (neuendor)
