I need generate a VCL ComboBox with whints for every Item in ComboBox, and
the Hint must appear every time I have highlighted one item from ComboBox,
not only when I have selected a Item, it works on ListBox and other
components but not in a ComboBox.
By the way VCL ComboBox componet hasn't a OnHighlighted Event or similar, it
exist only in CLX ComboBoxComponent.
Thanks,

There is a method called ItemAtPos for the TListBox component, but doesn't
exist in the Combo Box.

and popping up a list box when the button etc. is pressed.
That way you would have a hint for each item in the list box.
