implements java.awt.event.FocusListener, java.awt.event.KeyListener, javax.swing.event.DocumentListener, java.awt.event.MouseListener

A class using a JLabel a JTextArea and a JButton to build an inputarea in a component. A dataarea always references a dataclass.

Properties
name	values	comment
id	*	Id of the object. Let it begin with DA_
dataclass	*	Reference to JEDataclass
tooltip		Text in Tooltip
editable	true false	Set to false will change the field to an outputfield.
border		Id of a border.
enabled	true false	Enables or disables the component.
XMLtag	*	The tagname used to serialize the item in xml format.

By default this property is false.
button	true false	Set true will set a button behind the field, which will send the id of the JEDataarea as an ActionCommand to the callBack
fieldlength		It will overwrite the value of JEDataclass. It sets the length of the JTextArea. It can be overwritten by maxfieldlength in jeglobal.
rows		It sets the rows in the JTextArea.
markingBackgorund	true false	Set to true will use the global background color.
mandatory	true false	Defines an entry as mandatory
markable	true false	The field will get a focus even it is not editable and you can copy data from it
scrollpane	true false	When set to true, the textfield will be scrollable.
