Summary: PaginationDecorator - decorating the page links
Initial Comment:
I had a requirement for a project I'm working on that specifies
a pagination nav bar that looks like this:
<< previous 1-20 | 21-40 | 41-49 next >>
displaytags provides a look for the pagination nav bar that looks
like this:
[first/prev] 1, 2, 3, 4 [next/last]
Using custom properties, it can be made to look like this:
<< previous 1 | 2 | 3 | 4 next >>
The page labels cannot be changed using the standard displaytags
code, so I modified the code to use a decorator to provide the
functionality. I've attached a diff that adds the requested
functionality.
Here's an example that yields the results required by the specs:
BEGIN JSP
<%@ taglib uri="display-tag" prefix="display" %>
...
<display:table
name="results"
property="items"
id="item"
pagesize="20"
decorator="dttest.SearchResultsDecorator"
paginationDecorator="dttest.SearchResultsPaginationDecorator"
requestURI="search.do">
<display:setProperty name="basic.show.header" value="false"/>
<display:setProperty name="paging.banner.group_size"
value="5"/>
<display:column property="labelWithMarkup"/>
</display:table>
...
END JSP
BEGIN Java (com/mmode/myphonepws/search/
SearchResultsPaginationDecorator.java)
package dttest;
import org.displaytag.decorator.PaginationDecorator;
import org.displaytag.pagination.NumberedPage;
/**

* page labels according to the PRD specification. The look of

*/
public class SearchResultsPaginationDecorator implements
PaginationDecorator {
/* (non-Javadoc)
* @see
org.displaytag.decorator.PaginationDecorator#decorate(org.displayt
ag.pagination.NumberedPage, int)
*/
public String decorate(NumberedPage page, int pageSize) {
int first = (page.getNumber()-1)*pageSize+1;
int last = first+page.getItemCount()-1;
return "" + first + "-" + last;
}
}
END Java

Forgot to mention, my changes are based off displaytag-1.0-b2 if
someone uses the patch.
