The WM_IME_COMPOSITIONFULL message is sent to an application when the IME window finds no space to extend the area for the composition window. The application should use the IMC_SETCOMPOSITIONWINDOW message to specify how to display the window.
Return Values
No return value.
Remarks
The wParam and lParam parameters are not used. The IME window, not the IME, sends this notification message by using the SendMessage message.
