* Note that you can use the same command class, nsDocumentStateCommand

* for these or future observer commands.
|
||||
* We check the input command param for different behavior
|
||||
*
|
||||
* How to use:
|
||||
* 1. Get the nsICommandManager for the current editor
|
||||
* 2. Implement an nsIObserve object, e.g:
|
||||
*
|
||||
* void Observe(
|
||||
* in nsISupports aSubject, // The nsICommandManager calling this Observer
|
||||
* in string aTopic, // command name, e.g.:"obs_documentCreated"
|
||||
* // or "obs_documentWillBeDestroyed"
|
||||
in wstring aData ); // ignored (set to "command_status_changed")
|
||||
*
|
||||
* 3. Add the observer by:
|
||||
* commandManager.addObserver(observeobject, obs_documentCreated);
|
||||
* 4. In the appropriate location in editorSession, editor, or commands code,
|
||||
* trigger the notification of this observer by something like:
|
||||
*
|
||||
* nsCOMPtr<nsICommandManager> commandManager = do_GetInterface(mDocShell);
|
||||
* nsCOMPtr<nsPICommandUpdater> commandUpdater = do_QueryInterface(commandManager);
|
||||
* if (!commandUpdater) return NS_ERROR_FAILURE;
|
||||
* commandUpdater->CommandStatusChanged(obs_documentCreated);
|
||||
*
|
||||
* 5. Use GetCommandStateParams() to obtain state information
|
||||
* e.g., any creation state codes when creating an editor are
|
||||
* supplied for "obs_documentCreated" command in the
|
||||
* "state_data" param's value

||||
*
