pseudo.Tree class

pseudo.Tree.Tree(pThis:MovieClip)

Tree constructor. You never use the constructor to create this component.

Parameters	None
Returns	Nothing
Example	None

pseudo.Tree.create(pOwner:MovieClip, strName:String, n :Number):pseudo.Tree

Use this static function to create new Tree on the specified movie clip. Never use constructor directly to do it.

Parameters

pOwner The movie clip on which the new Tree will be drawn.
strName The new Tree instance name.
nDepth The new Tree instance depth.

Returns

The reference to the new Tree instance

Example

    //create instance of the Tree class
    var tree:pseudo.Tree = pseudo.Tree.create(_root, "tree", 1);
    tree.setSize(200, 350);
    
    //Apply the skin to the Tree
    
    tree.setLook(pseudo.look.XPLook.getInstance());
    
    //Set cell class that will be used to render the tree items.
    tree.setCellClass(classes.CellTree);
    
    //Add some data to combobox. Data objects in the array should have three necessary flags:
    // "text" this flag will be used to draw the item label , "cellType" to determine if the item is folder (1)or the leaf (0)
    //"depth" is used to set an offset of the item in the tree
    var arrData:Array = new Array();
    arrData.push({text:"root 1", cellType:1, depth:0});
    arrData.push({text:"leaf 1", cellType:0, depth:1});
    arrData.push({text:"leaf 2", cellType:0, depth:1});
    arrData.push({text:"folder", cellType:1, depth:1});
    arrData.push({text:"leaf 1", cellType:0, depth:2});
    arrData.push({text:"folder", cellType:1, depth:2});
    arrData.push({text:"folder", cellType:1, depth:3});
    arrData.push({text:"folder", cellType:1, depth:4});
    arrData.push({text:"folder", cellType:1, depth:4});
    arrData.push({text:"folder", cellType:1, depth:5});
    arrData.push({text:"leaf 2", cellType:0, depth:2});
    arrData.push({text:"leaf 3", cellType:0, depth:1});
    arrData.push({text:"root 2", cellType:1, depth:0});
    arrData.push({text:"leaf 1", cellType:0, depth:1});
    arrData.push({text:"root 3", cellType:1, depth:0});
    arrData.push({text:"leaf 1", cellType:0, depth:1});
    arrData.push({text:"leaf 1", cellType:0, depth:0});
    
    tree.setTreeData(arrData);
    
    //
    tree.expandAll();
    
    tree.setSelId(0);
    
    tree.update();
    tree.draw();
    
    // This code will draw the Tree element using XP look and feel skin.
    // Please notice that you should always use some skin to create the component, 
    // this can be done like in this example, and the skin will be compiled into the swf file,
    // or you can use another technique and load the skin at a run time.

pseudo.Tree.getTreeData():Array

Returns the reference to the data array associated with this Tree.

Parameters	None
Returns	Array value
Example	None

pseudo.Tree.setTreeData(arrData:Array):Void

Function that sets the data associated with the tree. The data array that is the array of the objects. You can add more properties to these objects as many as you want but Data objects in the array should have three necessary flags:

   - "text" this flag will be used to draw the item label ,
   - "cellType" to determine if the item is folder (1)or the leaf (0)
   - "depth" is used to set an offset of the item in the tree
