Using the Text Manager to Monitor Global Settings
If you implement a core editor, you must monitor the changes that are made to global settings, because these changes may affect your instance of the editor. You can track the changes by listening to events raised by the text manager. For example, when you specify a global preference for the appearance or behavior of a component in the core editor, such as its document data object, the text manager stores this information and communicates it to all affected clients.
Text Manager Functions
The text manager raises events for a number of settings, including the following:
Whether a buffer is under source code control
How to register for file-change notifications
How to keep track of which views are associated with certain buffers
Text colorization preferences
Tab versus space preferences
Preferences that are unique to a given language are not managed by the text manager. These settings must be managed by each language service.
Event notification for the text manager is provided by the IVsTextManagerEvents interface. Implement this interface on your client object to handle events raised the text manager. You register for these events by using the IConnectionPointContainer interface on the text manager.
