Hi.
I wrote a getChildById function for this purpose/use case...
I create the grid and its children dynamically at runtime and give the
DisplayObjects
numerical ids.
Its one thing you miss in flex if you're used to using getElementById in
javascript.
So... this is container specific... I havent gotten round to generifying it
yet...
private function getChildById(g:Grid, id:int):DisplayObject {
for each (var gr:GridRow in g.getChildren()) {
for each (var gi:GridItem in gr.getChildren()) {
if (!(gi.getChildAt(0) is HBox)) {
if (gi.getChildAt(0) is Text) {
if (Text(gi.getChildAt(0)).id ==
String(id)) {
return Text(gi.getChildAt(0));
}
}
if (gi.getChildAt(0) is TextInput) {
if (TextInput(gi.getChildAt(0)).id ==
String(id)) {
return
TextInput(gi.getChildAt(0));
}
}
}
}
}
return null;
}
hth.
