Greetings - I am trying to utilize the method getIndexOf( Object anObject ) to see if a value is already in the ComboBox before trying to add a duplicate value. This method is implemented by the DefaultComboBoxModel - My question is this - how can I implement the DefaultComboBoxModel with a JComboBox? Thank you
There's a couple ways, but for what you want, the easiest is to just create your own instance of a DefaultComboBoxModel and pass that to your JComboBox's constructor... JComboBox(ComboBoxModel aModel)
then when you want to retrieve the model, just cast it to the right class after calling getModel()... DefaultComboBoxModel myModel = (DefaultComboBoxModel) myJComboBox.getModel() Then you can call all the DefaultComboBoxModel's methods.
