The SFTTREE_OWNERDRAWPARM structure is used to define an application-specific owner-draw callback routine, which is called whenever an object needs to be rendered.

typedef struct tagSftTreeOwnerDrawParm {
    LPFNSFTTREE_OWNERDRAWPROC lpfnOwnerDrawProc;
    SFTTREE_DWORD_PTR OwnerDrawUserData;
} SFTTREE_OWNERDRAWPARM, * LPSFTTREE_OWNERDRAWPARM;

typedef const SFTTREE_OWNERDRAWPARM * LPCSFTTREE_OWNERDRAWPARM;

Members

lpfnOwnerDrawProc

A pointer to a owner-draw callback routine, which is called every time an object needs to be rendered.

OwnerDrawUserData

An application-specific value.  This value is passed to the function lpfnOwnerDrawProc LPFNSFTTREE_OWNERDRAWPROC as OwnerDrawUserData parameter.  Could be used to pass a global storage area to the callback routine.
