Class FolderChangeMonitor

java.lang.Object
  com.mucommander.ui.main.table.FolderChangeMonitor

All Implemented Interfaces:

LocationListener, java.awt.event.WindowListener, java.lang.Runnable, java.util.EventListener

public class FolderChangeMonitor
extends java.lang.Object
implements java.lang.Runnable, java.awt.event.WindowListener, LocationListener

This file monitors changes in the current folder of a FolderPanel, checking periodically if the current folder's date has changed. If a change has been detected, the FolderPanel will be asked to refresh its current folder.

If the MainFrame which contains the monitored FolderPanel becomes inactive (lies in the background), monitoring on will be not happen until the MainFrame becomes active again.

Implementation note: the monitoring is done in one single thread for all folders, each folder being monitored one after another. Current folder refreshes are performed in a separate thread.
