SetWindowCompositionAttribute

Go to Home Page

Sets various information regarding DWM window attributes

Syntax

BOOL WINAPI SetWindowCompositionAttribute (
    HWND hwnd,
    WINCOMPATTRDATA* pAttrData
)

Parameters

hwnd
The window whose information is to be changed
pAttrData
Pointer to a structure which both specifies and delivers the attribute data

Return Value

Nonzero on success, zero otherwise. Call GetLastError on failure for more information.

Remarks

This function is the reciprocal to GetWindowCompositionAttribute and is identical to DwmSetWindowAttribute with the exception that the parameters after the HWND are packed in a struct, rather than passed individually.

The layout of the WINCOMPATTRDATA structure is detailed on the GetWindowCompositionAttribute page. The remarks that apply to the struct and its members apply here too.
