|
114 |
* <li>It's made according the MVC (Model-View-Controller) pattern.</li>
|
115 |
* <li>Uses a {@link DefaultComboBoxConfigurableLookUpModel DefaultComboBoxConfigurableLookUpModel} as a dataModel, which it's also configurable.</li>
|
116 |
* </ul>
|
117 |
* </p>
|
118 |

|
123 |

|
126 |
* <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
|
127 |
* <i>(flag: <code>DefaultComboBoxConfigurableLookUpModel.showAllItemsInListBox == false</code>)</i>; otherwise, if this flag isn't enabled,
|
