最近在CFLEX看到了几个很好的例子，整理一下发上来。注：所有代码都来自CFLEX。
1.动态创建 DataGrid 列。这个例子是根据XML中的节点值来创建DataGrid中的列，并且还包含了一些对列的属性得设置。
程序代码
creationComplete="initApp()">
import mx.controls.dataGridClasses.DataGridColumn;
import mx.controls.DataGrid;
import mx.collections.XMLListCollection;
import mx.controls.Alert;
[Bindable]
private var _xlcCatalog:XMLListCollection; //the dataProvider for the DG
//run by creationComplete
public function initApp():void
{
_xlcCatalog = new XMLListCollection(xmlCatalog.product); //wrap the XML product nodes in an XMLListCollection
buildDG(); //creates the dataGrid
}//initApp
private function buildDG():void
{
var aColumnDef:Array = getColumnDefArray(); //returns a noraml array of objects that specify DtaGridColumn properties
var oColumnDef:Object;
var dg:DataGrid = new DataGrid; //instantiate a new DataGrid
var dgc:DataGridColumn;
var aColumnsNew:Array = dg.columns
var iTotalDGWidth:int = 0;
for (var i:int=0;ioColumnDef = aColumnDef[i];
dgc = new DataGridColumn(); //instantiate a new DataGridColumn
dgc.dataField = oColumnDef.dataField; //start setting the properties from the column def array
dgc.width = oColumnDef.width;
iTotalDGWidth += dgc.width; //add up the column widths
dgc.editable = oColumnDef.editable;
dgc.sortable = oColumnDef.sortable
dgc.visible = oColumnDef.visible;
dgc.wordWrap = oColumnDef.wordWrap;
aColumnsNew.push(dgc) //push the new dataGridColumn onto the array
}
dg.columns = aColumnsNew; //assign the array back to the dtaGrid
dg.editable = true;
dg.width = iTotalDGWidth;
dg.dataProvider = _xlcCatalog; //set the dataProvider
this.addChild(dg); //add the dataGrid to the application
}//buildDG
//uses the first product node to define the columns
private function getColumnDefArray():Array
{
//Alert.show("colcount:" + xmlCatalog.toXMLString());
var aColumns:Array = new Array();
var node0:XML = xmlCatalog.product[0]; //get the first "product" node
var xlColumns:XMLList = node0.children(); //get its child nodes (columns) as an XMLList
var xmlColumn:XML
var oColumnDef:Object;
for (var i:int=0;ixmlColumn = xlColumns[i];
oColumnDef = new Object();
oColumnDef.dataField = xmlColumn.localName(); //make the dataField be the node name
switch (oColumnDef.dataField) { //conditional column property logic
case "name":
oColumnDef.width = 80;
oColumnDef.sortable = false;
oColumnDef.visible = true;
oColumnDef.editable = false;
oColumnDef.wordWrap = false;
break;
case "description":
oColumnDef.width = 200;
oColumnDef.sortable = false;
oColumnDef.visible = true;
oColumnDef.editable = false;
oColumnDef.wordWrap = true;
break;
case "price":
oColumnDef.width = 40;
oColumnDef.sortable = true;
oColumnDef.visible = true;
oColumnDef.editable = true;
oColumnDef.wordWrap = false;
break;
case "image":
oColumnDef.width = 100;
oColumnDef.sortable = false;
oColumnDef.visible = false;
oColumnDef.editable = false;
oColumnDef.wordWrap = false;
break;
default:
oColumnDef.width = 50;
oColumnDef.sortable = true;
oColumnDef.visible = true;
oColumnDef.editable = false;
oColumnDef.wordWrap = false;
break;
}
aColumns.push(oColumnDef);
}
return aColumns; //return the array
}//getColumnDefArray

2.在 Tree 中查找节点。在对话框中输入要查找的节点的值。
程序代码
[Bindable]
public var _xmlData:XML;
public function initApp():void
{
_xmlData =
trace("test")
}//initapp
//starts at the given node, walks up the tree opening nodes as it goes
private function expandParents(xmlNode:XML):void
{
while (xmlNode.parent() != null) {
xmlNode = xmlNode.parent();
myTree.expandItem(xmlNode,true, false);
}
}//expandParents
//uses e4x to find a node, then calls expand parents to make it visible,
//then selects it
private function findNodeById(sId:String):void
{
var xmllistDescendants:XMLList = _xmlData.descendants().(@eid == sId);
expandParents(xmllistDescendants[0]);
myTree.selectedItem = xmllistDescendants[0];
}//findNodeById
]]>
paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10">
showRoot="false" dataProvider="{_xmlData}" />
3.动态显示/隐藏 DataGrid 的列。在List中选中一个就会显示相应的 DataGrid 的列。
程序代码
creationComplete="initApp()">
import mx.controls.dataGridClasses.DataGridColumn;
//import mx.controls.DataGrid;
import mx.collections.XMLListCollection;
[Bindable]
private var _xlcCatalog:XMLListCollection; //the dataProvider for the DG
//run by creationComplete
public function initApp():void
{
_xlcCatalog = new XMLListCollection(xmlCatalog.product); //wrap the XML product nodes in an XMLListCollection
lstColumns.selectedItems = new Array(dgHideShow.columns[0]); //set the column list dataProvider to the DataGridColumns
}//initApp
private function hideShowColumns():void {
var aColumns:Array = dgHideShow.columns;
var aSelectedColumns:Array = lstColumns.selectedItems;
var dgc:DataGridColumn;
var sDataField:String;
var sDataFieldCur:String;
var bFound:Boolean
for (var i:int=0;ibFound = false
dgc = aColumns[i];
sDataField = dgc.dataField;
for (var j:int=0;jsDataFieldCur = aSelectedColumns[j].dataField;
if (sDataFieldCur == sDataField) {
bFound = true;
break;
}
}//for (var j:
if (bFound) {
dgc.visible = true;
}
else {
dgc.visible = false;
}
}// for (var i:
