// This variable controls the position of tooltips, if the position is not specified to
|
|
// the Tooltip widget or *TextBox widget itself. It's an array of strings with the values
|
|
// possible for `dijit/place.around()`. The recommended values are:
|
|
//
|
|
// - before-centered: centers tooltip to the left of the anchor node/widget, or to the right
|
|
// in the case of RTL scripts like Hebrew and Arabic
|
|
// - after-centered: centers tooltip to the right of the anchor node/widget, or to the left
|
|
// in the case of RTL scripts like Hebrew and Arabic
|
|
// - above-centered: tooltip is centered above anchor node
|
|
// - below-centered: tooltip is centered above anchor node
|
|
//
|
|
// The list is positions is tried, in order, until a position is found where the tooltip fits
|
|
// within the viewport.
|
|
//
|
|
// Be careful setting this parameter. A value of "above-centered" may work fine until the user scrolls
|
|
// the screen so that there's no room above the target node. Nodes with drop downs, like
|
|
// DropDownButton or FilteringSelect, are especially problematic, in that you need to be sure
|
|
// that the drop down and tooltip don't overlap, even when the viewport is scrolled so that there
|
|
// is only room below (or above) the target node, but not both.
