Thanks for that - it now works!!!! :) I did try setting the properties in the create children function but I think that they were tehn overwritten again by somethign else as I still got ... at the end of the text when it was too long.
If I call invalidateSize at the end of updateDisplayList instead of measure it works fine. many many thanks!! :) --- In [email protected], "Alex Harui" <[EMAIL PROTECTED]> wrote: > > I would set the textfield's props in createChildren after > super.createChildren. > > Calling measure from updateDisplayList is too late.
