Does anybody know how to do this? I would assume that it has
something to do with pushing an index on the selectedIndices property
but I have been unable to get it to work. I am able to select a
single element by setting selectedIndex to a valid index though. I do
also have multipleSelection="true" in my mxml. Here is my function:
public function selectList(data:Object)
{
var optionGroupList:mx.controls.List = mx.controls.List(optionGroup);
var lastIndex:Number = optionGroupList.length;
//Echo.debug("selectList called with data: " + data + " " +
contentProvider.length);
for (var i:Number = 0; i < contentProvider.length; ++i)
{
//Echo.debug("selectList: " + contentProvider[i].data + " == " +
data);
if (contentProvider[i].data == data.toString()) {
Echo.debug("selecting " + i);
if (optionGroupList.selectedIndices == undefined)
optionGroupList.selectedIndex = i;
else
optionGroupList.selectedIndices.push(i);
//optionGroupList.selectedIndices[lastIndex++] = i;
//optionGroupList.selectedItems.push(contentProvider[i]);
//optionGroupList.selectedIndex = i;
}
}
mx.controls.Alert.show("selected indices: " +
optionGroupList.selectedIndices.length);
//optionGroupList.layoutChildren();
}
