| 55 * The CCombo class represents a selectable user interface object | |
| 56 * that combines a text field and a list and issues notification | |
| 57 * when an item is selected from the list. | |
| 58 * <p> | |
| 59 * CCombo was written to work around certain limitations in the native | |
| 60 * combo box. Specifically, on win32, the height of a CCombo can be set; | |
| 61 * attempts to set the height of a Combo are ignored. CCombo can be used | |
| 62 * anywhere that having the increased flexibility is more important than | |
| 63 * getting native L&F, but the decision should not be taken lightly. | |
| 64 * There is no is no strict requirement that CCombo look or behave | |
| 65 * the same as the native combo box. | |
| 66 * </p> | |
| 67 * <p> | |
| 68 * Note that although this class is a subclass of <code>Composite</code>, | |
| 69 * it does not make sense to add children to it, or set a layout on it. | |
