Is there some way to set the width of the drop-down list of a JComboBox? Note, this is not the same thing as setting the width of the JComboBox itself (vis-a-vis setBounds() or setSize()). I've got my JComboBox set as wide as possible, but the thing is the items in the list are dynamic and user defined, and there is no way to predict the width of the widest item. Does anyone know how to do this?
