ITextStoreAnchorSink::OnLayoutChange method (textstor.h)

The ITextStoreAnchorSink::OnLayoutChange method is called when the layout (on-screen representation) of the document changes.

Syntax

HRESULT OnLayoutChange(
  TsLayoutCode lcode,
  TsViewCookie vcView
);

Parameters

lcode

Contains a TsLayoutCode value that defines the type of change.

vcView

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
S_OK
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.
