Technically the ComboBoxCellEditor uses our custom NatCombo as combo box control. This is internally creating a Table in the dropdown.
So to achieve your requirement you could
1. Create a custom NatCombo that extends the NatTable one and override setItems(String) -> this is the place the table items are created
2. Create a custom ComboBoxCellEditor that extends the NatTable one and override createEditorControl(Composite) to return your custom NatCombo
This way you should be able to create a combo box editor that shows icons.
it works! The problem that I have is, that in the dropdownlist the icons are shown, but when i select one, then the text is shown and not the icon. Could you please say to me, which method is responsible for shown selected text?
