java - HOWTO Select JSpinner date field when JSpinner gets focus -

i trying make jspinner (containing minute/second timer) work bunch of set-in-their-ways folks don't care beans mouse want every keystroke used to. works i'd last mile hardest.

what means in practice spinner should , behave when 1 of text fields gains focus looks , behaves after user has pressed arrow key 1 of fields.

spinner created follows:

this.countdown = new jspinner(this.model); this.editor = new jspinner.dateeditor(countdown, "m:ss"); jformattedtextfield textfield = editor.gettextfield(); 

step 1. when spinner comes looks this: ('|' indicates caret, bold indicates selction)

|1:00
(nothing selected)

step 2. if arrow pressed here looks this:

2|:00
(2 in minutes field selected)

step 3. if right arrow pressed here get:

2:|00
(nothing selected)

step 4. if arrow pressed here get

2:01|
(01 in seconds field selected)

i'd work in these cases in steps 2 , 4. when 1 of subfields gains focus, should selected.

is there way make happen?

maybe can use focuslistener.
