Java SE (Java Platform, Standard Edition)

Hi,
I need of a TextComponent in which the text can be inserted only sequentially, orizzontally;
without the possibility to go at the next line with the enter key command,
or pasting text blocks with more lines.

Practically, the Textfield do this, but I can't see all text I've written, if text is very long.

I want to display text on more lines, through wrap, like in a JTextArea, but I want the text must be inserted orizontally, char by char.

Thank you in advance.
