Used as a parameter for SetDrawTabCallback to define an application-specific drawing callback routine, which paints the tab labels.

typedef struct tagTabsDrawProcParm {
    SFTTABS_DRAWTABPROC lpfnDrawProc;   /* User supplied drawing callback routine */
    SFTTABS_DWORD_PTR UserData;         /* User supplied data */
} SFTTABS_DRAWPROCPARM, * LPSFTTABS_DRAWPROCPARM;

Members

lpfnDrawProc

A pointer to a drawing callback routine of type SFTTABS_DRAWTABPROC, which calculates the tab label size and paints tab labels.

UserData

An application specific value. This value is passed to the drawing callback (SFTTABS_DRAWTABPROC) as the UserData parameter.

Comments

The SFTTABS_DRAWPROCPARM structure is used as a parameter for SetDrawTabCallback to define an application-specific drawing callback routine, which paints the tab labels.

Example

C++

    // Register a drawing callback
    {
        SFTTABS_DRAWPROCPARM Parm = {
            CSampleDlg::DrawOneTabCallback,
            (SFTTABS_DWORD_PTR)(LPVOID)this // Pass this to callback as UserData
        };
        m_Tab.SetDrawTabCallback(&Parm);
    }
