java - JTextField AutoComplete

Question

Hello: How to add AutoComplete String for JTextField, getting auto complte list from Jtable column.

JTextField textfield = new JTextField();
JTable table =new JTable();

Answer 1

The SwingX library has a very handy AutoCompleteDecorator function.

Say you copy the values of your JTable column into an ArrayList called validValues. All you now need for autocompletion on the JTextField myTextField is the following code:

AutoCompleteDecorator.decorate(myTextField, validValues, true);

The third argument tells the autocomplete decorator whether you want strict matching, i.e. whether the user is allowed to enter values other than the ones in your JTable column or not.
