Have you seen the attractive cuff and bangle bracelets that are available now? Here's an easy way to find your favorite style-they're all sorted by price range. Link to the group that matches your budget and you're sure to find something you like (jewelry.about.com....-price.htm)
object you already use. This allows you to use and benefit from a sorted model after making only minimal changes to your existing application code base. You really can have your list model and sort it too. (java.sun.com....ted_jlist/)
list to find out where a new entry should go. Notice that if the user has selected an unordered sort, the code adds the entry to the end of the sorted model (java.sun.com....ted_jlist/)
implementation must convert the sorted -model index position to an unsorted-model index. The method uses the converted index to retrieve the desired element from the decoratee. How does it retrieve the desired element from the unsorted model? After converting the index to the unsorted model's index, th (java.sun.com....ted_jlist/)
method. Because the sorted and unsorted model should always have the same elements, the size should always be the same as well. In this method, the sorted model does not have to pass any work to the underlying unsorted model. Instead, it just gets the size from its own internal list, which contains pointer indices into the decorated model (java.sun.com....ted_jlist/)
event, the event object will contain information about which list cell was selected. However, your application must make a choice about which it will process: the sorted - or the unsorted-model values. Most likely, you will need to process elements in the original unsorted model because that model contains the data relevant to your application. However, the (java.sun.com....ted_jlist/)
Consequently, your code must convert the sorted -model selection to an unsorted-model selection. Once you have the index values for the original unsorted model, you can interact directly with the model just as you would normally. Code Example 11 shows the conversion method that the (java.sun.com....ted_jlist/)
object, you must be careful to convert the reported indices from those of the sorted model to those of the original unsorted model. After all, the real data is in the original model, not in our decorator model. Code Example 15 shows an example of a demo-application listener method that must convert the indices to act on a user's selection (java.sun.com....ted_jlist/)
itself. Converting your existing applications to use a sorted model should be relatively simple and require few changes . Just remember to convert the indices reported from the (java.sun.com....ted_jlist/)

Whether you're a sports fan, art lover, history buff, or you're just hoping to read the books that will give you a head start on college reading, these lists should hel (homeworktips.about.com...._Topic.htm)
This article describes how to produce sorted lists and uses a simple application to demonstrate concepts. You can download all the demo source code using the link at the end of this article. Although I developed the demo source as a NetBeans IDE 5.0 project, the demo's ANT script does not require that you use that IDE to compile or execute the application. The demo application uses the decorator design pattern to provide additional functionality to th (java.sun.com....ted_jlist/)
public int compareTo(Object o) { // Retrieve the element that this entry points to // in the original model. Object thisElement = unsortedModel.getElementAt(index); Sorted ListEntry thatEntry = (Sorted ListEntry)o; // Retrieve the element that thatEntry points to // in the original model. Object thatElement = unsortedModel.getElementAt(thatEntry.getIndex()); if (comparator instanceof Collator) { thisElement = thisElement.toString(); thatElement = thatElement.toString(); } // Compare the base model's elements using the provided comparator. int comparison = comparator.compare(thisElement, thatElement); // Convert to descending order as necessary. if (sortOrder == SortOrder.DESCENDING) { comparison = -comparison; } return comparison;} private int index; (java.sun.com....ted_jlist/)
