DWORD dwStyle;
POINT ptCurrentPos;
RECT rcArea;
} COMPOSITIONFORM;
Members
dwStyle
Position style. This member can be one of the following values:
| 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 given 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 given 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 given by rcArea. The coordinates are relative to the upper-left of the window containing the composition window. |
ptCurrentPos
Coordinates of the upper-left corner of the composition window.
rcArea
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.
