java - Detect the Windows key modifier -


how can detect windows key modifier keyevent? have add code:

textfield.addkeylistener(new keyadapter() {     public void keyreleased(keyevent e) {         if ((e.getkeycode() & keyevent.vk_escape) == keyevent.vk_escape) {             textfield.settext("");         }     } }); 

but problem is, when use windows zoom , try exit using win + escape, if focus in textfield, content clears. i've tried filter e.getmodifiersex(), returns 0. way i've found detect whether windows pressed or not, create boolean field , change it's value when windows pressed/released.

so, there way windows key pressure state keyevent escape released event?

the way used myself:

abstractaction escapeaction = abstractaction() {     public void actionperfomed(actionevent e) {         settext("");     } }  textfield.addcaretlistener(new caretlistener() {     @override     public void caretupdate(caretevent e) {         if (textfield.gettext() == null || textfield.gettext().isempty()) {             textfield.getactionmap().remove("escape");             textfield.getinputmap().remove(keystroke.getkeystroke(keyevent.vk_escape, 0));         } else {             textfield.getactionmap().put("escape", escapeaction);             textfield.getinputmap().put(keystroke.getkeystroke(keyevent.vk_escape, 0), escapeaction);         }     } });
