Hi,
This is my columns:
var columns:ArrayCollection = new ArrayCollection();
columns.addItem("parent");
columns.addItem("cell1");
columns.addItem("cell2");
columns.addItem("dummy");
let say 3 rows:
var data_:ArrayCollection = new ArrayCollection;
rowData_ = new Map();
rowData_.put(columns[0],"root1");
rowData_.put(columns[1],55);
rowData_.put(columns[2],100);
rowData_.put(columns[3],myObject[0]);
data_.addItem(rowData_);
rowData_ = new Map();
rowData_.put(columns[0],"root1");
rowData_.put(columns[1],34);
rowData_.put(columns[2],10);
rowData_.put(columns[3],myObject[1]);
data_.addItem(rowData_);
rowData_ = new Map();
rowData_.put(columns[0],"root1");
rowData_.put(columns[1],6);
rowData_.put(columns[2],60);
rowData_.put(columns[3],myObject[2]);
data_.addItem(rowData_);
My Map (which is a HashMap):
package
{
import flash.utils.Dictionary;
public class Map
{
private var keysList:Array = new Array();
private var valuesList:Array = new Array();
private var entries:Dictionary = new Dictionary();
public function Map(){
}
public function get length():uint
{
return valuesList.length;
}
public function get(key:Object):Object
{
return entries[key];
}
public function getKeyAt(index:uint):Object
{
return keysList[index];
}
public function getKeysList():Array
{
return keysList.slice();
}
public function getValueAt(index:uint):Object
{
return valuesList[index];
}
public function getValuesList():Array
{
return valuesList.slice();
}
public function put(key:Object, value:Object):void
{
entries[key] = value;
keysList.push(key);
valuesList.push(value);
}
public function remove(key:Object):void
{
delete entries[key];
var index:int = keysList.indexOf(key);
if (index > -1)
{
keysList.splice(index, 1);
valuesList.splice(index, 1);
}
}
}
}
The result is data_ ArrayCollection that holds a list of column/value
hashmap which is good.
How do I take this array and translate it to a dataProvider for the
DataGrid, or set it differently to the grid?
Thanks man
