nsIDOMRange getRangeAt (in long index)
 Returns the range at the specified index.
void collapse (in nsIDOMNode parentNode, in long offset)
 Collapses the selection to a single point, at the specified offset in the given DOM node.
void extend (in nsIDOMNode parentNode, in long offset)
 Extends the selection by moving the focus to the specified node and offset, preserving the anchor postion.
void collapseToStart ()
 Collapses the whole selection to a single point at the start of the current selection (irrespective of direction).
void collapseToEnd ()
 Collapses the whole selection to a single point at the end of the current selection (irrespective of direction).
boolean containsNode (in nsIDOMNode node, in boolean entirelyContained)

Member Function Documentation

Adds a range to the current selection.

void nsISelection::collapse ( in nsIDOMNode  parentNode,
in long  offset 
)

Collapses the selection to a single point, at the specified offset in the given DOM node.

When the selection is collapsed, and the content is focused and editable, the caret will blink there.

Parameters:
parentNodeThe given dom node where the selection will be set
offsetWhere in given dom node to place the selection (the offset into the given node)

Collapses the whole selection to a single point at the end of the current selection (irrespective of direction).

If content is focused and editable, the caret will blink there.

Collapses the whole selection to a single point at the start of the current selection (irrespective of direction).

If content is focused and editable, the caret will blink there.

boolean nsISelection::containsNode ( in nsIDOMNode  node,
in boolean  entirelyContained 
)

The value of entirelyContained determines the detail of the search to determine if the selection contains the node.

If entirelyContained is set to PR_TRUE, t or false if

Parameters:
nodeThe node where the selection will be extended to
entirelyContainedWhether

Deletes this selection from document the nodes belong to.

void nsISelection::extend ( in nsIDOMNode  parentNode,
in long  offset 
)

Extends the selection by moving the focus to the specified node and offset, preserving the anchor postion.

The new selection end result will always be from the anchor to the new focus, regardless of direction.

Parameters:
parentNodeThe node where the selection will be extended to
offsetWhere in node to place the offset in the new focused node

Returns the range at the specified index.

Removes all ranges from the current selection.

Removes a range from the current selection.

Adds all children of the specified node to the selection.

Parameters:
parentNodethe parent of the children to be added to the selection.

Modifies the cursor Bidi level after a change in keyboard direction.

Parameters:
langRTLis PR_TRUE if the new language is right-to-left or PR_FALSE if the new language is left-to-right.

Returns the whole selection into a plain text string.
