Well what I want is to be able to assign labelFunction dynamicly.
Depending on a selection I build an array of columns wich some have
labelFunctions to format de data.At the end I replace current columns
by the new array.
If I define a fixed column in a dg whe labelFunction set I can watch
the object trought debugger and get this sctructure
dg.__columns[someindex].__labelFunction{object}
> __proto__
> constructor
> func
> prototype
> target
When I try to simulate the same behavior with AS
<!------------------------>
var colunas:array = new Array();
var DataGridColumn = new mx.controls.gridclasses.DataGridColumn;
DataGridColumn.columnName = "data_fim";
DataGridColumn.__header = "Até";
DataGridColumn.labelFunction= {func:eurodate,target:this};
DataGridColumn.textAlign = "center";
colunas.push(DataGridColumn);
// eurodate beeing the function I want to be used and colunas the new
array to be used by the dg.
dg.columns = colunas;
<!------------------------>
I get the following object
> __proto__
> constructor
> func
> target
no prototype is defined for this object. Is this the approach to build
with actionScript a dgcolumn?
