The ITextStoreAnchorSink::OnSelectionChange method is called when the selection within the text stream changes. This method should be called whenever the return value of a potential call to ITextStoreAnchor::GetSelection has changed.
Syntax
HRESULT OnSelectionChange();
Return value
This method can return one of these values.
| Value | Description |
|---|---|
|
The method was successful. |
|
The manager holds a lock on the document. |
Remarks
This method only needs to be called when the application modifies the selection itself, not when a client modifies the selection with ITextStoreAnchor::SetSelection, ITextStoreAnchor::InsertTextAtSelection, or other ITextStoreAnchor methods.
When calling this method, the application must be able to grant a document lock.
Applications should expect reentrant client calls to ITextStoreAnchor::RequestLock from within this method. An application can grant the lock request synchronously, or, because several changes have been cached, it can grant the lock asynchronously.
