I have a few JComboBox instances in a GUI I've made. They all start off empty and get populated by the user, but because they start empty they look rubbish on the screen. I can't for the life of me find a way to set a default string to appear in an otherwise empty combo box. I just want to put in "-----" or something to set an initial size.
