Based on yesterday's blog entry, let's do something semi useful and display, in the project popup, which
is available when you right-click a project in the Projects window, the time since the last
change was made anywhere in the project, i.e., we can listen recursively
to any changes done within a project and then update the popup with the
newly acquired information, dynamically:

projects.addLookupListener(

resultChanged(new LookupEvent(projects));
}
@Override
public void resultChanged(LookupEvent le) {
Collection<? extends Project> allProjects = projects.allInstances();
if (allProjects.size() == 1) {
Project currentProject = allProjects.iterator().next();
if (!timedProjects.contains(currentProject)) {
String currentProjectName =
ProjectUtils.getInformation(currentProject).getDisplayName();
putValue("popupText", "Start Timer for Project: " + currentProjectName);

"Current Project: " + currentProjectName);
timedProjects.add(currentProject);

}
}
}
@Override

}
protected void refresh() {
startTime = System.currentTimeMillis();
String formattedStartTime = formatter.format(startTime);
putValue("popupText", "Timer started: " + formattedStartTime + " ("
+ ProjectUtils.getInformation(context).getDisplayName() + ")");
}
@Override
public void fileChanged(FileEvent fe) {
changedTime = System.currentTimeMillis();
formatter = new SimpleDateFormat("mm:ss");
String formattedLapse = formatter.format(changedTime - startTime);
putValue("popupText", "Time since last change: " + formattedLapse + " ("
+ ProjectUtils.getInformation(context).getDisplayName() + ")");
startTime = changedTime;
}
@Override
public void fileFolderCreated(FileEvent fe) {}
@Override

@Override
public void fileDeleted(FileEvent fe) {}
@Override
public void fileRenamed(FileRenameEvent fre) {}
@Override
public void fileAttributeChanged(FileAttributeEvent fae) {}
}
Some more work needs to be done to complete the above, i.e., for each
project you somehow need to maintain the start time and last change and
redisplay that whenever the user right-clicks the project.
