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 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
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.
