TextField#setInputEventTimeout issue


I would like to set a custom timeout on a TextField.
From the manual :



A text change in the user interface causes the event to be communicated to the application after a timeout period. If more changes are made during this period, the event sent to the server-side includes the changes made up to the last change. The length of the timeout can be set withsetInputEventTimeout().

I tried this :
TextField tf = new TextField();

But the “setInputEventTimeout” is unrecognized. I use Vaddin 7.5.8.

Could you help me ?

Thanks in advance
