Creating and Destroying a Cursor

The following code fragment shows how an application should respond to a WM_SETFOCUS message when using a cursor in a particular window:

    LONG   curXPos,curYPos,curWidth,curHeight;

    case WM_SETFOCUS:
        if (SHORT1FROMMP(mp2)) {

            /* Gain the focus. */
            WinCreateCursor(hwnd, curXPos, curYPos, curWidth, curHeight,
                CURSOR_SOLID | CURSOR_FLASH, (PRECTL) NULL);
            WinShowCursor(hwnd, TRUE);
        }
        else {

            /* Lose the focus. */
            WinDestroyCursor(hwnd);
        }

        return 0;
