How can I clear the textfield when it is enabled?

Question

The textfield is disabled and with text.

When I touch a button, the textfield will be enabled for editing.

However, I would like to textfield to be cleared when enabled.

One constraint is that I can;t add any other listener to the button.

Is there anyone can answer my question?

Many Thanks!

You could attach a property listener and listen for the "enabled" event

field.addPropertyChangeListener("enabled", listener);

This doesn't require you mess around with the field at all...
