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