java - jpanel implementing button behavior -

-

i want create radio button has more components default jradiobutton. i'm wondering best method is, should subclass jradiobutton adding components or better subclass jpanel , add behavior of radio button shown below.

---------jpanel--------------- - titel (label)              - - radiobutton (jradiobutton) - - description (label)        - ------------------------------

the whole panel should focusable , should provide feedback when clicked or has focus. help.

none of above.

  • don't extend components unless genuinely need extend functionality, not merely decoration.

  • don't confuse containment hierarchy class hierarchy.

  • don't defeat existing focus subsystem unless plan provide own.

  • if want alter appearance of panel when radio button's focus changes, in focus listener attached button. background color of opaque panel bound property, setbackground() should sufficient.
