No-Wrap
This style causes 
Multiline entry-fields to show a horizontal scroll-bar when the text of a line goes over the field size. Without this style, the exceeding text is automatically moved to the next line and no scroll-bars are shown.
 
Example - Define an entry-field control that doesn’t wrap text
