Class TreeHelper

java.lang.Object
  com.jalios.jcms.workspace.TreeHelper

public class TreeHelper
extends Object

Convenient class to construct complex UI tree of workspaces and groups. This class gives two set of static methods : - the first one to manage the hierarchy of workspaces; - the second to produce the HTML that make a hierarchy presentation of workspaces, with possibly, the groups in there. The structure in the DOM of the tree with workspaces and groups is as follows : for the top : div#wshierarchy.wsnode => div.wscontent : always open => div#globalgroupset.groupset -> class 'open' is added when clicked on div#globalgroupset_title => div#globalgroupset_title : title for COMMON groups (WITHOUT any WS), only if groups are required => ul.wsgroupset : list of groups without WS, only if groups are required => ul.wstree : sub wsnodes for root WS (according to the loggedMember). => div#allwsgroupset.groupset -> class 'open' is added when clicked on div#allwsgroupset_title => div#allwsgroupset_title : title for WORKSPACE groups (with a WS), only if groups are required => ul.wstree : sub wsnodes for root WS (according to the loggedMember). for a workspace node : li.wsnode => div.ajax-refresh-div => a.ajax-refesh => span.wstitle : for the WS title corresponding to a node => div.wscontent : section that has to be open or closed => div.groupset => => ul.wsgroupset : list of groups for that WS, only if groups are required => must be open only on demand => ul.wstree : sub wsnodes for sub WS. When nodes are opened (Workspaces or groups), their ids with prefix are set as classes of an hidden div of id 'hiddenDivForOpenNodes'. When a link is clicked, the javascript JCMS.treews.TreeHelper.addClassOpenGroup(link) add the value of the class in the queryString.
