Class ChannelDropHandler

java.lang.Object

org.lsst.ccs.gconsole.plugins.trending.ChannelDropHandler

All Implemented Interfaces:

DropTargetListener, EventListener, org.freehep.jas.services.PlotRegionDropHandler

public class ChannelDropHandler
extends Object
implements org.freehep.jas.services.PlotRegionDropHandler

Drop handler that supports drag-and-dropping trending channel nodes into plotter regions. Note that with the current implementation of org.freehep.jas.plugin.plotter.DefaultRegion, drop(DropTargetDropEvent) is the only method of this class that ever gets called, and the user action is always ACTION_LINK. This makes it impossible to let the user choose what happens on every particular drop - the operation is set through preferences.
