public class JEList
extends JEComponent

Implements a JList. See a demonstration in the program JEasyExample tab "Components".

Properties :

• id
  The unique id of the root object.


• XMLTag
  The xml tag used when serializing or deserializing the component in a JEMessage.


• referenceId
  A reference for this jeasy object used to identify this type of jeasy object even if it was cloned. It is used for locale properties of the object and may be used for identification in messages. If no reference is set, the jeasy id will be set as default.


• label
  The label of this component.


• columns
  It sets the length of a field in characters. It can be overwritten by maxColumns in jeglobal.


• scrollPane
  Optional vertical and horizontal scroll bars.


• font (reference to JEFont)
  The font for this component.


• labelFont (reference to JEFont)
  The font for the label.


• mnemonic
  Sets the keyboard mnemonic on the current model. The mnemonic is the key which when combined with the look and feel's mouseless modifier (usually Alt) will activate this button if focus is contained somewhere within this button's ancestor window.


• toolTipText
  The text to display in a tool tip. The text displays when the cursor lingers over the component.


• buttonBehind (reference to JEButton)
  The id of a button behind the field. The button will send the id of the root component in front as an ActionCommand to the callBack.


• border (reference to JEBorder)
  The border of this component.


• constraints (reference to JEConstraints)
  The contraints for this component used for GridBagLayout Manager.


• labelConstraints (reference to JEConstraints)
  The contraints for the label used for GridBagLayout Manager.


• foreground (reference to JEColor)
  Id of a color used as the foreground of the component.


• background (reference to JEColor)
  Id of a color used as the background of the component.


• visible
  Sets whether or not this component is visible.


• enabled
  Sets whether or not this component is enabled.


• editable
  Sets whether or not this component can be edited.


• mandatory
  Sets whether or not this component is mandatory. A mandatory component must have a value before serializing.


• entries
  A list entries used to select by this component.


• referenceButtonBehind
  A reference for this jeasy object used to identify this type of jeasy object even if it was cloned. It is used for locale properties of the object and may be used for identification in messages. If no reference is set, the jeasy id will be set as default.


• animation (reference to JEAnimation)
  The animation used for this object and, if it is defined for parentobjects, for all children.
