/** VERSION: BETA
|
| 83 |
* <p>A configurable combo box component that lists items that carry out with the criterions of a <code>ILookUp</code> agent,
|
| 84 |
* considering the text in its inner editor.</p>

| 85 |
*
|
| 86 |

|
| 89 |
* <li>Inherits from JComboBox.</li>
|
| 90 |
* <li>Has 6 flags to configure its behaviour.</li>
|
| 91 |
* <li>It's made according the MVC (Model-View-Controller) pattern.</li>
|
| 92 |
* <li>Uses a {@link DefaultComboBoxConfigurableLookUpModel DefaultComboBoxConfigurableLookUpModel} as a dataModel, which it's also configurable.</li>
|
| 93 |
* </ul>
|
| 94 |
* </p>
|
| 95 |
*
|
| 96 |
* <p>Configuration flags:
|
| 97 |
* <ul>
|
| 98 |

|
| 99 |
* <li><b>BeepEnabled:</b> rings a beep sound if there is no item that matches with the text written according the <code>ILookUp</code> agent, or not.</li>
|
| 100 |
* <li><b>HidePopupIfThereAreNoItems:</b> hides popup (list box) if there is no item that matches with the text written according the <code>ILookUp</code> agent, or uses the default (JComboBox and more) behaviour.</li>
|
| 101 |
* <li><b>ToForceSelectAnItem:</b> forces to select an item (if the component looses the focus or user presses the Enter keyboard key), or uses the default (JComboBox and more) behaviour.</li>
|
| 102 |
* <li><b>CompleteArrowKeySelection:</b> writes in the editor the value of the element selected by the arrow keys (up or down) if its enabled, otherwise holds the previous text.</li>
|
| 103 |
* <li><b>DisplayAllItemsWithArrowButton:</b> <i>true</i>: displays all this component's dataModel items if its <i>popup</i> it's hided, and this component's dataModel listed only the matches
|
| 104 |
* <i>(flag: <code>DefaultComboBoxConfigurableLookUpModel.showAllItemsInListBox == false</code>)</i>; otherwise, if this flag isn't enabled,
|
| 105 |
* won't display all items in that situation.</li>
|
