Members

dwStyle

Position style. This member can be one of the following values.

Value	Meaning
CFS_DEFAULT	Moves 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	Displays 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	Displays 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	Displays 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

A RECT structure containing the coordinates of the upper-left and lower-right corners of the composition window.

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.
