License: MIT-style license. Credits: Inspired by: - WebFX xTree, - Destroydrop dTree, Changes: rev.12: - load() only worked once on the same node, fixed. - the script would sometimes try to get 'R' from the server, fixed. - the 'load' attribute is now supported in XML files (see example_5.html). rev.13: - enable() and disable() added - the adopt() and load() methods use these to improve performance by minimizing the number of visual updates. rev.14: - toggle() was using enable() and disable() which actually caused it to do extra work - fixed. rev.15: - adopt() now picks up 'href', 'target', 'title' and 'name' attributes of the a-tag, and stores them in the data object. - adopt() now picks up additional constructor arguments from embedded comments, e.g. icons, colors, etc. - documentation now generates properly with NaturalDocs, rev.16: - onClick events added to MooTreeControl and MooTreeNode - nodes can now have id's - method can be used to find a node with a given id rev.17: - changed icon rendering to use innerHTML, making the control faster (and code size slightly smaller). rev.18: - migrated to MooTools 1.2 (previous versions no longer supported) */ var MooTreeIcon = ['I','L','Lminus','Lplus','Rminus','Rplus','T','Tminus','Tplus','_closed','_doc','_open','minus','plus']; /* Class: MooTreeControl This class implements a tree control. Properties: root - returns the root object. selected - returns the currently selected object, or null if nothing is currently selected. Events: onExpand - called when a node is expanded or collapsed: function(node, state) - where node is the object that fired the event, and state is a boolean meaning true:expanded or false:collapsed. onSelect - called when a node is selected or deselected: function(node, state) - where node is the object that fired the event, and state is a boolean meaning true:selected or false:deselected. onClick - called when a node is clicked: function(node) - where node is the object that fired the event. Parameters: The constructor takes two object parameters: config and options. The first, config, contains global settings for the tree control - you can use the configuration options listed below. The second, options, should contain options for the constructor - please refer to the options listed in the documentation. Config: div - a string representing the div Element inside which to build the tree control. mode - optional string, defaults to 'files' - specifies default icon behavior. In 'files' mode, empty nodes have a document icon - whereas, in 'folders' mode, all nodes are displayed as folders (a'la explorer). grid - boolean, defaults to false. If set to true, a grid is drawn to outline the structure of the tree. theme - string, optional, defaults to 'mootree.gif' - specifies the 'theme' GIF to use. loader - optional, an options object for the constructor - defaults to {icon:'mootree_loader.gif', text:'Loading...', color:'a0a0a0'} onExpand - optional function (see Events above) onSelect - optional function (see Events above) */ var MooTreeControl = new Class({ initialize: function(config, options) { options.control = this; // make sure our new MooTreeNode knows who it's owner control is options.div = config.div; // tells the root node which div to insert itself into this.root = new MooTreeNode(options); // create the root node of this tree control this.index = new Object(); // used by the get() method this.enabled = true; // enable visual updates of the control this.theme = config.theme || 'mootree.gif'; this.loader = config.loader || {icon:'mootree_loader.gif', text:'Loading...', color:'#a0a0a0'}; this.selected = null; // set the currently selected node to nothing this.mode = config.mode; // mode can be "folders" or "files", and affects the default icons this.grid = config.grid; // grid can be turned on (true) or off (false) this.onExpand = config.onExpand || new Function(); // called when any node in the tree is expanded/collapsed this.onSelect = config.onSelect || new Function(); // called when any node in the tree is selected/deselected this.onClick = config.onClick || new Function(); // called when any node in the tree is clicked this.root.update(true); }, /* Property: insert Creates a new node under the root node of this tree.

Defaults to the root node of the parent control. Note: The ul/li structure must be properly nested, and each li-element must contain one a-element, e.g.: > The "href", "target", "title" and "name" attributes of the a-tags are picked up and stored in the data property of the node. CSS-style comments inside a-tags are parsed, and treated as arguments for constructor, e.g. "icon", "openicon", "color", etc. */ adopt: function(id, parentNode) { if (parentNode === undefined) parentNode = this.root; this.disable(); this._adopt(id, parentNode); parentNode.update(true); document.id(id).destroy(); this.enable(); }, _adopt: function(id, parentNode) { /* adopts a structure of ul/li elements into this tree */ e = document.id(id); var i=0, c = e.getChildren(); for (i=0; i to turn on visual updates again, and automatically repaint all nodes that were changed. */ disable: function() { this.enabled = false; }, /* Property: enable Enables visual updates again after a call to */ enable: function() { this.enabled = true; this.root.update(true, true); } }); /* Class: MooTreeNode This class implements the functionality of a single node in a .

Options: text - this is the displayed text of the node, and as such as is the only required parameter. id - string, optional - if specified, must be a unique node identifier. Nodes with id can be retrieved using the method. color - string, optional - if specified, must be a six-digit hexadecimal RGB color code. open - boolean value, defaults to false. Use true if you want the node open from the start. icon - use this to customize the icon of the node. The following predefined values may be used: '_open', '_closed' and '_doc'. Alternatively, specify the URL of a GIF or PNG image to use - this should be exactly 18x18 pixels in size. If you have a strip of images, you can specify an image number (e.g. 'my_icons.gif#4' for icon number 4). openicon - use this to customize the icon of the node when it's open. data - an object containing whatever data you wish to associate with this node (such as an url and/or an id, etc.) Events: onExpand - called when the node is expanded or collapsed: function(state) - where state is a boolean meaning true:expanded or false:collapsed. onSelect - called when the node is selected or deselected: function(state) - where state is a boolean meaning true:selected or false:deselected. onClick - called when the node is clicked (no arguments). */ var MooTreeNode = new Class({ initialize: function(options) { this.text = options.text; // the text displayed by this node this.id = options.id || null; // the node's unique id this.nodes = new Array(); // subnodes nested beneath this node (MooTreeNode objects) this.parent = null; // this node's parent node (another MooTreeNode object) this.last = true; // a flag telling whether this node is the last (bottom) node of it's parent this.control = options.control; // owner control of this node's tree this.selected = false; // a flag telling whether this node is the currently selected node in it's tree this.color = options.color || null; // text color of this node this.data = options.data || {}; // optional object containing whatever data you wish to associate with the node (typically an url or an id) this.onExpand = options.onExpand || new Function(); // called when the individual node is expanded/collapsed this.onSelect = options.onSelect || new Function(); // called when the individual node is selected/deselected this.onClick = options.onClick || new Function(); // called when the individual node is clicked this.open = options.open ? true : false; // flag: node open or closed? this.icon = options.icon; this.openicon = options.openicon || this.icon; // add the node to the control's node index: if (this.id) this.control.index[this.id] = this; // create the necessary divs: this.div = { main: new Element('div').addClass('mooTree_node'), indent: new Element('div'), gadget: new Element('div'), icon: new Element('div'), text: new Element('div').addClass('mooTree_text'), sub: new Element('div') } // put the other divs under the main div: this.div.main.adopt(this.div.indent); this.div.main.adopt(this.div.gadget); this.div.main.adopt(this.div.icon); this.div.main.adopt(this.div.text); // put the main and sub divs in the specified parent div: document.id(options.div).adopt(this.div.main); document.id(options.div).adopt(this.div.sub); // attach event handler to gadget: this.div.gadget._node = this; this.div.gadget.onclick = this.div.gadget.ondblclick = function() { this._node.toggle(); } // attach event handler to icon/text: this.div.icon._node = this.div.text._node = this; this.div.icon.onclick = this.div.icon.ondblclick = this.div.text.onclick = this.div.text.ondblclick = function() { this._node.control.select(this._node); } }, /* Property: insert Creates a new node, nested inside this one.
