java - How perform task on javaFX TextField at onfocus and outfocus? -
i working on javafx project. need perform task on javafx textfield
.
for example on "on focus" event textfield
want print
system.out.println("textfield on focus");
and on "out focus" event should print
system.out.println("textfield out focus");
i thought might helpful see example specifies changelistener anonymous inner class scottb mentioned.
textfield yourtextfield = new textfield(); yourtextfield.focusedproperty().addlistener(new changelistener<boolean>() { @override public void changed(observablevalue<? extends boolean> arg0, boolean oldpropertyvalue, boolean newpropertyvalue) { if (newpropertyvalue) { system.out.println("textfield on focus"); } else { system.out.println("textfield out focus"); } } });
