[flexcoders] Finding all TextInputs in a Panel

[Shidan]

I would like to find all the TextInputs in a Panel but when I do a for
in loop over the Panel I get nothing.

for (var 0:Object in panel){
Alert.show(o.toString());
}

Can someone give me a pointer.

Thanks,
Shidan

for...in iterates over properties.  Unless you've subclassed the panel and
gave each TextInput child its own variable, then this won't give you a
Container's children.  What you want is to iterate over the children:

for (var i:int = 0; i  panel.getChildren().length; i++) {
  var child:DisplayObject = panel.getChildAt(i);
  if (child is TextInput) {
 // do something useful
  }
}

This will only work if the TextInputs are direct children of the panel.
Otherwise things will get a bit more tricky.

Or you could use a for-each loop to loop over the children:

 

for each ( var child : * in panel.getChildren() )

{

if ( child is TextInput )

{

//do something

}

}
