public class Pager
extends WidgetBase

The Pager widget is used to display a list of links horizontally in a page selection user interface. The user can select a page to jump to, go to prev/next page, or go to the first or last page. This widget needs to know the numberOfPages total, and the currentPage the user is on currently, so this widget must be fed this information from the code.

Methods

Modifier and Type	Method and Description
int	getCurrentPage() The current page being shown by this pager widget (this must be set when the page is changed)
String	getLinkScript() The script to execute when a link is clicked (should probably use the "this" var in most cases, to determine page number selected - see retrieveStackedPage(linkElement, collectionId) js function)
int	getMaxNumberedLinksShown() The maximum number of NUMBERED links shown at once for pages, if number of pages that exist exceed this value, the pager omits some pages before and/or after the current page (which are revealed during while navigating using a carousel effect)
int	getNumberOfPages() Number of pages TOTAL that make up the component being paged (this must be set by the framework based on some list size)
int	getPagesEnd() The last page number to render; this is set by the framework
int	getPagesStart() The first page number to render; this is set by the framework
boolean	isRenderFirstLast() Returns true if this pager widget is rendering the "First" and "Last" links
boolean	isRenderPrevNext() Returns true if this pager widget is rendering the "Prev" and "Next" links
void	performFinalize(Object model, LifecycleElement parent) performFinalize calculates the pagesStart and pagesEnd properties (using numberOfPages, currentPage, and maxNumberedLinksShown - these must be set) which determines pages shown by the widget
void	setCurrentPage(int currentPage) Set the current page
void	setLinkScript(String linkScript) Set the link js script
