IMC_SETCOMPOSITIONWINDOW Overview  Group

An application sends the IMC_SETCOMPOSITIONWINDOW message to an IME window to set the style of the composition window. The message set this style in the current input context and the style is subsequently applied to each IME window that receives that input context.

msg = (UINT) WM_IME_CONTROL;
wParam = (WPARAM) IMC_SETCOMPOSITIONWINDOW;
lParam = (LPARAM) &CompForm;
 

Parameters

lParam

Pointer to the COMPOSITIONFORM structure that contains the style information.

Return Values

Remarks

By default, the IME window has the CFS_POINT style. This means the IME window uses the current caret position and window client area when it opens composition window.
