How to add a OnKeyPressed like listener on a textfield

[Fabrice Kabongo]

I have to do countdown of place remaining on a fieldtext, i didn't find something like a OnKeyPressed listener. i've just tried with a actionEvent listener but it's update my countdown only when the user quit(take off the focus from the text field) the textfield.

It looks like this:

protected void onActualite_BreveContenuAction(Component c, ActionEvent event)
{
    findActualiteCaractereCount().setText(String.valueOf(160-findBreveContenu().getText().length()));
   
}

You need to use data change listener not key listener since the virtual keyboards don't broadcast key events.

Just so I'm clear, in the before show of the form use findMyTextField(f).addDataChangeListener(....);
