Hello there,

I´ve got a problem with the JComboBox! I get a List of items, which I add to a JComboBox but I´m only able to add the "TEXT" to it. But I also have to add a ID, which identifies the Text, to the ComboBox. Do you have any Solution for my problem??

Thanks a lot for your help!

Greetings
Markus

The ComboBoxModel holds Object. You can make an object with those fields. Make its toString retrun what you want and it#'ll be displayed

Just add instances of this class to your model:

public class MyData {
      private int id;
      private String text;

      public void setId(int id) {
            this.id = id;
      }

      public int getId() {
            return id;
      }

      public void setText(String text) {
            this.text = text;
      }

      public String getText() {
            return text;
      }
      
      public String toString() {
            return text;
      }

}

I have to beg to differ and that's no disrespect to mayank. His link, while useful, does not deal directly with your specific problem

Ah, so CEHJ takes the name finally in his 9 years at EE ;-)

mfAudi, if the sample code on the link which I posted helped you and if that was the one you used, then you should split the points between CEHJ and me because he had also posted a similar code earlier.

I'll ask Venabili to re-open.
