    The wxDocMDIParentFrame class provides a default top-level frame for
    applications using the document/view framework. This class can only be used
    for MDI parent frames.

    It cooperates with the wxView, wxDocument, wxDocManager and wxDocTemplate
    classes.

        difficult, the implementation of this function is shown below:

        }
