PRBool containsNode ( nsIDOMNode node , PRBool partlyContained )

Indicates whether the node is part of the selection. If partlyContained is set to PR_TRUE, the function returns true when some part of the node is part of the selection. If partlyContained is set to PR_FALSE, the function only returns true when the entire node is part of the selection.

Arguments:

node

partlyContained

void deleteFromDocument ( )

Deletes this selection from document the nodes belong to.

void extend ( nsIDOMNode parentNode , PRInt32 offset )

Extends the selection by moving the selection end to the specified node and offset, preserving the selection begin position. The new selection end result will always be from the anchorNode to the new focusNode, regardless of direction.

Arguments:

parentNode: The node where the selection will be extended to

offset: Where in node to place the offset in the new selection end

nsIDOMRange getRangeAt ( PRInt32 index )

Returns the range at the specified index.

Arguments:

index

void removeAllRanges ( )

Removes all ranges from the current selection.

void removeRange ( nsIDOMRange range )

Removes a range from the current selection.

Arguments:

range

void selectAllChildren ( nsIDOMNode parentNode )

Adds all children of the specified node to the selection.

Arguments:

parentNode: the parent of the children to be added to the selection.

void selectionLanguageChange ( PRBool langRTL )

Modifies the cursor Bidi level after a change in keyboard direction
