Value Meaning
CFS_DEFAULT Move the composition window to the default position. The IME window can display the composition window outside the client area, such as in a floating window.
CFS_FORCE_POSITION Display the upper left corner of the composition window at exactly the position specified by ptCurrentPos. The coordinates are relative to the upper left corner of the window containing the composition window and are not subject to adjustment by the IME.
CFS_POINT Display the upper left corner of the composition window at the position specified by ptCurrentPos. The coordinates are relative to the upper left corner of the window containing the composition window and are subject to adjustment by the IME.
CFS_RECT Display the composition window at the position specified by rcArea. The coordinates are relative to the upper left of the window containing the composition window.

ptCurrentPos

A POINT structure containing the coordinates of the upper left corner of the composition window.

rcArea

Remarks

Some IME windows adjust the composition window position specified by the system or the application. The CFS_FORCE_POSITION directs the IME window to skip this adjustment.
