// x: Integer

|

// 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,

//
|

|

// 1. (BL, TL)
|

|
|
// 2. (TL, BL)
|

// 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,
