java - JButton keyboard shortcuts -

-

i have 2 jbuttons , allow them used keyboard arrow keys whenever jframe has focus.

can point me in right direction this?

modified swing's action demo.

the initialization of button:

// sets mnemonic down, no hint display jbutton down = new jbutton(new downaction("down", null, "this down button", new integer(keyevent.vk_down));

the action:

class downaction extends abstractaction {     public downaction(string text, imageicon icon,                   string desc, integer mnemonic) {         super(text, icon);         putvalue(short_description, desc);         putvalue(mnemonic_key, mnemonic);     }     public void actionperformed(actionevent e) {         displayresult("action first button/menu item", e);     } }
