-    A combobox is like a combination of an edit control and a listbox. It can
-    be displayed as static list with editable or read-only text field; or a
-    drop-down list with text field; or a drop-down list without a text field.

+    or a drop-down list with text field; or a drop-down list without a text
+    field depending on the platform and presence of wxCB_READONLY style.

 
     A combobox permits a single selection only. Combobox items are numbered
     from zero.
