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

68 * <p>
