IMC_GETCOMPOSITIONWINDOW

An application sends the IMC_GETCOMPOSITIONWINDOW message to an IME window to get the position of the composition window. Because the IME may adjust the position of a composition window, an application uses this message to get the actual position to decide whether to reposition the window.

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

Parameters

lParam

Pointer to the COMPOSITIONFORM structure that receives the position of the composition window.

Return Values

Returns zero if successful, nonzero otherwise.

Remarks

The returned position is in window coordinates relative to the window having the current input focus.
