All Implemented Interfaces:

Direct Known Subclasses:

MediTreeExpansionDispatcher

public abstract class AbstractTreeExpansionDispatcher

extends java.lang.Thread

It is an "event dispatcher" for tree expansions, i.e. it manages in a separate thread tree expansions. You have only to inherit this method: doDispatchOne: what you have to do when you are expanding a node. Once created your own class, use this sequence of commands: AbstractTreeExpansioDispatcher disp = new YourClass(); disp.setStatusLabelSync(myStatusLabelSync); disp.start(); disp.expand(myTree, mySelectionPath); disp.stopAll();

Field Summary

protected StatusLabelSync

statusSync The status label sync to be used to display messages.
