Examples of org.itsnat.comp.list.ItsNatComboBox

org.itsnat.comp.list.ItsNatComboBox
Is the base interface of combo box components.
Items of combo boxes are not editable "in place", for instance a call to {@link #setItsNatListCellEditor(ItsNatListCellEditor)} throws an{@link org.itsnat.core.ItsNatException}.

By default this component type uses a javax.swing.DefaultComboBoxModel data model.

When the selection item changes the component notifies to all java.awt.event.ItemListener listeners registered (this component implements java.awt.ItemSelectable).
