ITfContextOwnerServices::OnLayoutChange method (msctf.h)
The ITfContextOwnerServices::OnLayoutChange method is called by the context owner when the on-screen representation of the text stream is updated during a composition. Text stream updates include when the position of the window that contains the text is changed or if the screen coordinates of the text change.
Syntax
HRESULT OnLayoutChange();
Return value

| Value | Description |

The method was successful. |
Remarks
A call to ITfContextOwnerServices::OnLayoutChange could be in response to a text edit, font size change, window movement/resizing, and so on.
If a call to ITfContextView::GetTextExt or ITfContextOwner::GetACPFromPoint fails because the application did not calculate the screen layout (Return Value: TS_E_NOLAYOUT), the application must then call ITfContextOwnerServices::OnLayoutChange when the information is ready.
