Examples of com.vaadin.ui.TextField

com.vaadin.ui.TextField

A text editor component that can be bound to any bindable Property. The text editor supports both multiline and single line modes, default is one-line mode.

Since TextField extends AbstractField it implements the {@link com.vaadin.data.Buffered} interface. A TextField isin write-through mode by default, so {@link com.vaadin.ui.AbstractField#setWriteThrough(boolean)} must be calledto enable buffering.
