ITfContextOwnerServices::OnLayoutChange method

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();

Parameters

This method has no parameters.

Return value

This method can return one of these values.

ValueDescription
S_OK

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.
