WINDOWCOMPOSITIONATTRIBDATA structure

  • 아티클

Describes a key/value pair that specifies a window composition attribute and its value. This structure is used with the GetWindowCompositionAttribute and SetWindowCompositionAttribute functions.

Syntax

typedef struct tagWINDOWCOMPOSITIONATTRIBDATA {
    WINDOWCOMPOSITIONATTRIB Attrib;
    void* pvData;
    UINT cbData;
} WINDOWCOMPOSITIONATTRIBDATA;

Fields

Attrib

A flag describing which value to get or set, specified as a value of the WINDOWCOMPOSITIONATTRIB enumeration. This parameter specifies which attribute to get or set, and the pvData member points to an object containing the attribute value.

pvData

When used with the GetWindowCompositionAttribute function, this member contains a pointer to a variable that will hold the value of the requested attribute when the function returns. When used with the SetWindowCompositionAttribute function, it points an object containing the attribute value to set. The type of the value set depends on the value of the Attrib member. For information about what type of value you should pass a pointer to in the pvData member, see WINDOWCOMPOSITIONATTRIB.

cbData

The size of the object pointed to by the pvData member, in bytes.
