Attributes

Attribute Type Description
type short Returns the type of the selection (see nsISelectionController for available constants). Read only.

Methods

GetRangesForInterval()

Return array of ranges intersecting with the given DOM interval.

void GetRangesForInterval(
  in nsIDOMNode beginNode,
  in PRInt32 beginOffset,
  in nsIDOMNode endNode,
  in PRInt32 endOffset,
  in PRBool allowAdjacent,
  out PRUint32 resultCount,
  [retval, array, size_is(resultCount)] out nsIDOMRange results
);
Parameters
beginNode
beginOffset
endNode
endOffset
These four parameters represent the range to compare against the selection.
allowAdjacent
Specifies whether the returned ranges are allowed to touch the input range rather than merely overlapping it.
resultCount
Returns the number of ranges that overlap (or touch) the input range.
results
Returns the ranges that overlap (or touch) the input range.

Native code only!

GetRangesForIntervalCOMArray

void GetRangesForIntervalCOMArray(
  in nsIDOMNode beginNode,
  in PRInt32 beginOffset,
  in nsIDOMNode endNode,
  in PRInt32 endOffset,
  in PRBool allowAdjacent,
  in RangeArray results
);
Parameters
beginNode
beginOffset
endNode
endOffset
These four parameters represent the range to compare against the selection.
allowAdjacent
Specifies whether the returned ranges are allowed to touch the input range rather than merely overlapping it.
results
Returns the ranges that overlap (or touch) the input range.

Requires Gecko 1.9 (Firefox 3)

scrollIntoView()

Scrolls a region of the selection, so that it is visible in the scrolled view.

void scrollIntoView(
  in short aRegion,
  in boolean aIsSynchronous,
  in short aVPercent,
  in short aHPercent
);
Parameters
aRegion
The region inside the selection to scroll into view (see selection region constants defined in nsISelectionController).
aIsSynchronous
When true, scrolls the selection into view before returning. If false, posts a request which is processed at some point after the method returns.
aVPercent
How to align the frame vertically. A value of 0 means the frame's upper edge is aligned with the top edge of the visible area. A value of 100 means the frame's bottom edge is aligned with the bottom edge of the visible area. For values in between, the point "aVPercent" down the frame is placed at the point "aVPercent" down the visible area. A value of 50 centers the frame vertically. A value of -1 means move the frame the minimum amount necessary in order for the entire frame to be visible vertically (if possible).
aHPercent
How to align the frame horizontally. A value of 0 means the frame's left edge is aligned with the left edge of the visible area. A value of 100 means the frame's right edge is aligned with the right edge of the visible area. For values in between, the point "aHPercent" across the frame is placed at the point "aHPercent" across the visible area. A value of 50 centers the frame horizontally . A value of -1 means move the frame the minimum amount necessary in order for the entire frame to be visible horizontally (if possible).
