JCombobox Listener how to enable it when item is selected?

Question

I have a JComboBox that displays Name From database Patients_Details

public void ComboItem() {

chooser.removeAllItems();
chooser.addItem(\"Please Select...\");         


        

Answer 1

Simply add an ActionListener to the combo box. When actionPerformed is called, you can look up the selected value and call what ever methods you need to.

For example:

chooser.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        Object selectedValue = chooser.getSelectedValue();
        // carry on with what ever you need
    }
});
