        @param priorThis

        in the first variant. There are two versions of this function
        to allow this parameter to be either an id or name to
        a property.

        @param newproperty
        Pointer to the inserted property. wxPropertyGrid will take
        ownership of this object.

        @param parent
        New property is inserted under this category. Available only
        in the second variant. There are two versions of this function
        to allow this parameter to be either an id or name to
        a property.

        @param index
        Index under category. Available only in the second variant.

        @remarks

        - wxPropertyGrid takes the ownership of the property pointer.

        - While Append may be faster way to add items, make note that when
          both types of data storage (categoric and
          non-categoric) are active, Insert becomes even more slow. This is
          especially true if current mode is non-categoric.

        Example of use:

        @code

            // append category
            wxPGProperty* my_cat_id = propertygrid->Append(
                new wxPropertyCategory("My Category") );
