[scriptable, uuid(ab6fe746-300b-4ab4-abb9-1c0e3977874c)]

Attributes

 The number of rows currently selected in this tree.

readonly attribute long count

 The current column.

attribute nsITreeColumn currentColumn

 The current item (the one that gets a focus rect in addition to being
 selected).

attribute long currentIndex

 This attribute is a boolean indicating whether or not the
 "select" event should fire when the selection is changed using
 one of our methods.  A view can use this to temporarily suppress
 the selection while manipulating all of the indices, e.g., on 
 a sort.
 Note: setting this attribute to false will fire a select event.

attribute boolean selectEventsSuppressed

 The selection "pivot".  This is the first item the user selected as
 part of a ranged select.

readonly attribute long shiftSelectPivot

 This attribute is a boolean indicating single selection.

readonly attribute boolean single

 The tree widget for this selection.

attribute nsITreeBoxObject tree

void clearRange(in long startIndex, in long endIndex)

 Clears the selection.

void clearSelection()

void getRangeAt(in long i, out long min, out long max)

 Iterate the selection using these methods.

 Can be used to invalidate the selection.

void invalidateSelection()

 Inverts the selection.

void invertSelection()
