IMC_SETCOMPOSITIONWINDOW
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
Returns zero
if successful, nonzero otherwise.
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.
