Examples of ptolemy.actor.gui.EditorFactory

ptolemy.actor.gui.EditorFactory

This is an attribute that can create an editor for interactively configuring its container. If you place an instance of this class inside a Ptolemy II object, then when a user double clicks on the object or selects Configure from the context menu, instead of the default behavior (which is to edit parameters), the createEditor() method of this class is called.

This differs from EditorPaneFactory in that it is responsible to every aspect of creating the editor. Thus, it has to create a top-level window, rather than just a pane to insert in a top-level window.

In this base class, the createEditor() method is abstract. Derived classes must override this method to present a user interface for configuring the object. For example, a digital filter actor could present a filter design interface. A plotter actor could present a panel for configuring a plot. A file reader actor could present a file browser. @see EditorPaneFactory @author Edward A.
