How can I get an event when the user types a key in the TextField of a JComboBox?
Created May 4, 2012
Sandip Chitale This simply becomes a problem of getting at the textfield of a editable combobox.
if (combo.isEditable()) {
Component c = combo.getEditor().getEditorComponent();
if (c instanceof JTextField) {
JTextField tf = (JTextField) c;
// now listen for key types or
// add Document listener to the
// backing the textfield
}
}
How to listen on typed keys is a well understood problem. Hints are -
- textfield.addKeyListener(...)
- textfield.getDocument().addDocumentListsner(...); // better
