+ // DOM node (typically a button); place popup relative to this node. (Specify this *or* "x" and "y" parameters.)
+ // x: Integer
+ // Absolute horizontal position (in pixels) to place node at. (Specify this *or* "around" parameter.)
+ // y: Integer
+ // Absolute vertical position (in pixels) to place node at. (Specify this *or* "around" parameter.)
+ // orient: Object|String
+ // When the around parameter is specified, orient should be an
+ // ordered list of tuples of the form (around-node-corner, popup-node-corner).
+ // dijit.popup.open() tries to position the popup according to each tuple in the list, in order,
+ // until the popup appears fully within the viewport.
+ //
+ // The default value is {BL:'TL', TL:'BL'}, which represents a list of two tuples:
+ // 1. (BL, TL)
+ // 2. (TL, BL)
+ // where BL means "bottom left" and "TL" means "top left".
+ // So by default, it first tries putting the popup below the around node, left-aligning them,
+ // and then tries to put it above the around node, still left-aligning them. Note that the
+ // default is horizontally reversed when in RTL mode.
+ //
+ // When an (x,y) position is specified rather than an around node, orient is either
+ // "R" or "L". R (for right) means that it tries to put the popup to the right of the mouse,
+ // specifically positioning the popup's top-right corner at the mouse position, and if that doesn't
+ // fit in the viewport, then it tries, in order, the bottom-right corner, the top left corner,
+ // and the top-right corner.
+ // onCancel: Function
+ // callback when user has canceled the popup by
+ // 1. hitting ESC or
+ // 2. by using the popup widget's proprietary cancel mechanism (like a cancel button in a dialog);
+ // i.e. whenever popupWidget.onCancel() is called, args.onCancel is called
+ // onClose: Function
+ // callback whenever this popup is closed
+ // onExecute: Function
+ // callback when user "executed" on the popup/sub-popup by selecting a menu choice, etc. (top menu only)
