ITextStoreAnchorSink::OnLayoutChange method
The ITextStoreAnchorSink::OnLayoutChange method is called when the layout (on-screen representation) of the document changes.
Syntax
HRESULT OnLayoutChange( [in] TsLayoutCode lcode, [in] TsViewCookie vcView );
Parameters
- lcode [in]
-
Contains a TsLayoutCode value that defines the type of change.
- vcView [in]
-
Contains an application-defined cookie that identifies the document. For more information, see ITextStoreAnchor::GetActiveView.
Return value
This method can return one of these values.
| Value | Description |
|---|---|
|
The method was successful. |
Remarks
A layout change can be in response to a change to the text, font size, window movement, window resizing, or other change that affects the displayed text.
If a call to ITextStoreAnchor::GetTextExt or ITextStoreAnchor::GetAnchorFromPoint returns TS_E_NOLAYOUT because the application has not calculated the layout, the application must call ITextStoreAnchorSink::OnLayoutChange when the layout is available.
