This interface represents a spelling checker. Implement this interface to add support for a new spell checking engine.

Inherits from: nsISupports Last changed in Gecko 1.7

This interface represents a spell checking engine. The built in Hunspell engine has contract ID "@mozilla.org/spellchecker/engine;1". Extensions can use this interface to check spelling or provide its own spell checker to editors.

Method overview

void addDirectory(in nsIFile dir);

boolean check(in wstring word);

void getDictionaryList([array, size_is(count)] out wstring dictionaries, out PRUint32 count);

void removeDirectory(in nsIFile dir);

void suggest(in wstring word,[array, size_is(count)] out wstring suggestions, out PRUint32 count);

Attribute	Type	Description
`copyright`	`wstring`	A string indicating the `copyright` of the engine. Not currently used. Read only.
`dictionary`	`wstring`	The name of the current `dictionary` used by `check()` and `suggest()`. This will be either element from the array returned by `getDictionaryList()` or an empty string if no dictionary is selected. Note: Setting this value to a value that doesn't match an existing dictionary throws a `NS_ERROR_FILE_NOT_FOUND` exception. When this attribute's value is changed, a "spellcheck-dictionary-update" notification is sent. If the dictionary was set to "no dictionary" (that is, by specifying an empty string), the observer may select another dictionary before returning.
`language`	`wstring`	The `language` this spell checker is using when checking. This is the language of `dictionary`. Read only. When this changes, the spell checker sends a "spellcheck-dictionary-update" notification.
`name`	`wstring`	The `name` of the engine. Not currently used. Read only.
`personalDictionary`	`mozIPersonalDictionary`	The personal `dictionary`.
`providesPersonalDictionary`	`boolean`	Does the engine provide its own `personalDictionary`? Read only.
`providesWordUtils`	`boolean`	Does the engine provide its own word utilities? Read only.

Requires Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0 / SeaMonkey 2.7)

Adds all the dictionaries in the specified directory to the spell checker.

void addDirectory(
  nsIFile dir
);

dir: An nsIFile object indicating the directory from which to add dictionaries.

Checks a word to determine if it's spelled correctly.

When this changes, the spell checker sends a "spellcheck-dictionary-update" notification.

boolean check(
  in wstring word
);

Returns true if word is spelled correctly according to the dictionary attribute, and returns false if word is misspelled.

Gets the list of dictionaries.

void getDictionaryList(
  [array, size_is(count)] out wstring dictionaries,
  out PRUint32 count
);

dictionaries: A list of dictionaries supported by this spell checker. The dictionary attribute can be set to one of these. Each dictionary name is typically but not always a locale code.
count: The length of dictionaries.

Requires Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0 / SeaMonkey 2.7)

Removes all the dictionaries in the specified directory from the spell checker.

void removeDirectory(
  nsIFile dir
);

dir: An nsIFile object indicating the directory whose spell checkers are to be removed from the spell checker.

Gets a list of suggestions for a misspelled word.

When this changes, the spell checker sends a "spellcheck-dictionary-update" notification.

void suggest(
  in wstring word,
  [array, size_is(count)] out wstring suggestions,
  out PRUint32 count
);
