Focus management on Field

[cravemusic]

It would be useful to have the focus capabilities of the Field class extended. I propose the following:

boolean isFocused(): return true if this field has focus

void blur(): Blur a field without placing focus on another field. If this is called on a field that does not have focus, it's a no op.

Here are a few other additions I would use if they existed:

void allowFocus(boolean): Allow an instance of the Field class to not gain focus.

Reason: Currently, if you have an AdapterField between two TextFields, the browser attempts to focus the AdapterField, even if the contents of such a field cannot be focused. I'd rather have a better keyboard nav experience by allowing my tabbing to skip over fields I designate as non-focusable.

void setFocusIndex(int): Set the explicit order in which fields receive focus when pressing the tab key. In HTML, this can be represented on <input> as the tabindex attribute.

I just noticed that you can blur a field through its El representation, so that one can be crossed off the list. But, the others would still be great to have.

Check out setTabIndex method.

JP, thanks for pointing out that method. I had not looked for this functionality in the El class when I originally wrote this.
