COMBOBOX #handle.ext, array$(), eventHandler, xPos, yPos, wide, high

Comboboxes are a lot like listboxes, but they are designed to save space.  Instead of showing an entire list of items, they show only the selected one.  When the user clicks on the checkbox arrow button (to the right), a list appears (drops down).  It is then possible to browse the possible selections, and pick one if so desired.  When the selection is made, the new selection is highlighted.  The user can type into the textbox part on top of the combobox, rather than choosing an item from the dropdown list.  The program can get the contents of this field. The combobox is loaded with a collection of strings from a specified string array, and a reload command updates the contents of the combobox from the array when the contents of array change.
