Tk::After - support class for Tk::Widget::after
$id = $widget->after(time,callback); $id = $widget->afterIdle(callback); $widget->afterCancel($id); $id = $widget->repeat(period,callback);
Internally this class is used to implement above.
$id = Tk::After->new($widget,$time,'method',callback); $id->cancel;
This class is a wrapper used by Tk::Widget::after to auto-cancel after calls when a widget is destroyed.
callback is a normal perl/Tk callback. Method is either 'once' or 'repeat'
This is first attempt at the code and interface is likely to change. So for the time being at least use $widget->after(...) interface.
