Constants

Load Flags

Constant	Value	Description
`eNone`	0
`eNext`	1
`ePrevious`	2
`eNextWord`	3
`ePreviousWord`	4
`eToBeginningOfLine`	5
`eToEndOfLine`	6

Attributes

Attribute	Type	Description
`contentsMIMEType`	`string`	The MIME type of the document.
`document`	`Document`	Read only. The DOM Document this editor is associated with.
`documentCharacterSet`	`ACString`	Sets the current 'Save' document character set.
`documentIsEmpty`	`boolean`	Read only. Returns `true` if the document has no meaningful content.
`documentModified`	`boolean`	Read only. Returns `true` if the document is modifed and needs saving.
`flags`	`unsigned long`	Edit flags for this editor. May be set at any time.
`isDocumentEditable`	`PRBool`	Read only. Returns `true` if we have a document that is not marked read-only.
`isSelectionEditable`	`boolean`	Read only. `true` if the current selection anchor is editable; otherwise `false`. This helps to support cases where only parts of the document are editable, by letting you see if the current selection is in an editable section.
`rootElement`	`nsIDOMElement`	Read only. The root editable element, which for a document is its body.
`selection`	`nsISelection`	Read only. The selection/caret for this editor. In the case of a design mode document, this is the same as the window's selection.
`selectionController`	`nsISelectionController`	Read only. The selection controller for the current presentation.

init

Initializes the editor's services.

[noscript] void init(
  in nsIDOMDocument doc,
  in nsIPresShellPtr shell, Obsolete since Gecko 5
  in nsIContent aRoot,
  in nsISelectionController aSelCon,
  in unsigned long aFlags
);

Parameters

doc: The document to observe.
shell Obsolete since Gecko 5.0: The nsIPresShellPtr representing the presentation shell displaying the document. This parameter was removed in Gecko 5.0 (Firefox 5.0 / Thunderbird 5.0 / SeaMonkey 2.2).
aRoot: The root of the editable section of this document; if it's null, the editor gets its root from document.body.
aSelCon: The nsISelectionController object used to get selection location information. This should be null for HTML editors.
aFlags: A bit mask of flags controlling the editor's behavior. Need to document what the possible values are.
