    @class wxCursor
    @wxheader{cursor.h}

    A cursor is a small bitmap usually used for denoting where the mouse
    pointer is, with a picture that might indicate the interpretation of a
    mouse click. As with icons, cursors in X and MS Windows are created
    in a different manner. Therefore, separate cursors will be created for the
    different environments.  Platform-specific methods for creating a @b wxCursor
    object are catered for, and this is an occasion where
    conditional compilation will probably be required (see wxIcon for
    an example).

    A single cursor object may be used in many windows (any subwindow type).
    The wxWidgets convention is to set the cursor for a window, as in X,
    rather than to set it globally as in MS Windows, although a
    global ::wxSetCursor is also available for MS Windows use.

        Copy constructor, uses @ref overview_trefcount "reference counting".
        
        @param bits
            An array of bits.
        @param maskBits
            Bits for a mask bitmap.
        @param width
            Cursor width.
        @param height
            Cursor height.
        @param hotSpotX

        @param type
            Icon type to load. Under Motif, type defaults to wxBITMAP_TYPE_XBM. Under
        Windows,
            it defaults to wxBITMAP_TYPE_CUR_RESOURCE. Under MacOS, it defaults to
        wxBITMAP_TYPE_MACCURSOR_RESOURCE.
            Under X, the permitted cursor types are:

            Load an X bitmap file.
        
        
        
        
        
            Under Windows, the permitted types are:
