/**
* A Combo Box provides a way to select a string from a list of strings.
* Unless COMBOBOX_STATIC is passed, it also allows the user to enter a new
* string into the text field, for example if the desired entry is not in the
* list of strings.  Passing COMBOBOX_REPLACE, COMBOBOX_INSERT_BEFORE, COMBOBOX_INSERT_AFTER,
* COMBOBOX_INSERT_FIRST, or COMBOBOX_INSERT_LAST causes a newly entered text to replace the
* current one in the list, or be added before or after the current entry, or to be added at
* the beginning or end of the list.
* Combo Box is intended to enter text; if you need to enter a choice from a list of
* options, it is recommended that the List Box widget is used instead.
* When the text in the field is changed, a SEL_COMMAND will be send to the target.
* The Combo Box can also receive ID_GETSTRINGVALUE and ID_SETSTRINGVALUE and so
* on, which will behave similar to Text Field in that they will retrieve or update
* the value of the field.
