Examples of org.itsnat.comp.text.ItsNatHTMLInputFile

org.itsnat.comp.text.ItsNatHTMLInputFile
Is the interface of text based components which text is rendered/edited as a single line using an HTML input element with type "file".
ItsNat provides a default implementation of this interface.

This component is "passive", do not try to set a file path explicitly calling {@link #setText(String)} or using the data model because for security reasons browsers reject or ignorea initial value of an <input> file element or any attempt to set this value using JavaScript (to avoid an unadvertised file upload), only the user can set a file path. Anyway the file path introduced by the user is automatically sent to the server and ready to read calling {@link #getText()} or reading thedata model.
