COMPOSITIONFORM Structure

Contains position information for a composition window.

Syntax

typedef struct {
    DWORD dwStyle;
    POINT ptCurrentPos;
    RECT  rcArea;
}COMPOSITIONFORM;

Members

dwStyle

Unsigned long integer value that contains the position style. This can be one of the following values:

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 corner of the window containing the composition window.

ptCurrentPos

POINT value that contains the coordinates of the upper-left corner of the composition window.

rcArea

RECT value that contains the coordinates of the upper-left and lower-right corners of the composition window.

Remarks

This structure maps to the COMPOSITION structure documented in the Microsoft® Platform Software Development Kit (SDK).
