Checkbox, Radio: api to set/get checked state

[bill]

See related dijit forum topic.

Most form widgets have setValue()/getValue() methods but for checkbox and radio buttons, the "value" field is more like the name field; what you need is a function to get/set the checked state.

Example code to illustrate problem:

<input type=radio name=seatType value=coach checked>
<input type=radio name=seatType value=business>
<input type=radio name=seatType value=firstClass>

For a given input we want the ability to set whether or not it is "checked", not what the value (coach/business/firstClass) is.

a quick first attempt, adding checked state API to FormElement?.js and using it in Checkbox.js

[davidb]

this solution might be better; just adds api to Checkbox.js (reposting to add this comment)

(In [8373]) setChecked()/getChecked() API. Fixes #2869. Patch by David Bolter (CLA on file).

this improves the solution (setChecked updates view, removed unecessary aria etc)

Hi Bill,

Could you please commit the checkedapifix.diff patch I just added? It makes sure the view is updated when the user calls setChecked; it also removes some ARIA stuff that I accidentally borrowed when pasting code from my FormElement? solution.

I've been adding some tests for checkbox/radio but am not ready to commit the them just yet, and can do that on another ticket.
