Is it possible to detect a date change on a JCalendar JDateChooser field?
I'd like to detect when the date is changed in a JDateChooser field so that I can update another field.
Is this possible? And if so where should I be starting? I've already looked at the documentation and unfortunately there are no methods for adding something like an ActionListener or StateChangeListener (开发者_如何学Pythonmy first thoughts).
com.toedter.calendar.JCalendar
inherits a listenerList
from JComponent
and it implements java.beans.PropertyChangeListener
. I'd add a listener and see what comes though.
Edit: I think you can use addPropertyChangeListener()
the same way JCalendar
does.
JDateChooser chooser = new JDateChooser();
chooser.getDateEditor().addPropertyChangeListener(
new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent e) {
if ("date".equals(e.getPropertyName())) {
System.out.println(e.getPropertyName()
+ ": " + (Date) e.getNewValue());
}
}
});
this.add(chooser);
I've not tried it, but addDateListener(DateListener listener)
looks appropriate.
