java - How to invoke JTable action from outside JButton? -

i have jtable transferhandler allows copy-cut-paste actions via hotkeys or dnd. have 3 jbuttons (copy-cut-paste) outside of jtable, should invoke similar actions on jtable's transferhandler (such canimport() etc).

how can that?

basically similar approach in recent question/answer: find table's copy action in actionmap, wrap custom action delegates original , use custom action in button:

table.setdragenabled(true); final action copy = table.getactionmap().get("copy"); action copywithbutton = new abstractaction("copy") {      @override     public void actionperformed(actionevent e) {         copy.actionperformed(                 new actionevent(table, e.getid(), e.getactioncommand()));     } }; frame.add(new jscrollpane(table)); frame.add(new jbutton(copywithbutton), borderlayout.north); frame.add(new jscrollpane(new jtextarea(5, 20)), borderlayout.south);
