If you want to enable the check box on the second row, you communicate through the data
provider. Any change to the data provider (when made through a DataProvider method such
as
DataProvider.editField()
code would be written in the Flash application, either on a frame, on an object, or in another
class file (but not in the cell renderer class file):
// calls setValue() again
myGrid.editField(1, "enabled", true);
The following example loads an image in a loader component within the cell, depending on
the value passed:
function setValue(suggested, item, selected) : Void
{
/* Hide anything normally rendered in the cell if item is undefined.
Otherwise update the cell contents with the new data.
*/
if (item == undefined){
loader._visible = false;
}else{
// clear the loader
loader.contentPath = undefined;
// the list has URLs for different images in its data provider
if (suggested!=undefined){
loader.contentPath = suggested;
}
}
}
The following example is from a multiline text cell renderer:
function setValue(suggested:String, item:Object, selected:Boolean):Void
{
/* Hide anything normally rendered in the cell if item is undefined.
Otherwise update the cell contents with the new data.
*/
if (item == undefined){
multiLineLabel._visible = false;
}else{
// adds the text to the label
multiLineLabel.text = suggested;
}
}
) calls to refresh the display of the grid. This
setValue()
