java - What is best way to create popup menu like in eclipse on Ctrl+F6? -

i want create popup menu same in eclipse on ctrl+f6.

it should have jscrollbar , list of strings each item has small border.

i have idea use jdialog how make not display border , close buttons jlist scroll bar?

thank you!

the easiest , straightforward way use jpopupmenu class. can add jcomponent jpopupmenu, not jmenuitems.

here's button when clicked, shows jlist in popup without close buttons, scroll bar. wherever popup (the jlist) loses focus, popup automatically closed.

final jbutton b = new jbutton("press me"); b.addactionlistener(new actionlistener() {     @override     public void actionperformed(actionevent e) {         final defaultlistmodel<string> model = new defaultlistmodel<>();         (int = 0; < 100; i++)             model.addelement(i + ".");         final jlist<string> l = new jlist<>(model);          final jpopupmenu pm = new jpopupmenu();         final jscrollpane sp = new jscrollpane(l);         // pm.setpreferredsize(new dimension(100, 300));         pm.add(sp);         pm.show(b, 0, 0);     } });
