    // MyResizableListCtrl(){} constructor in addition to your regular one.

        These parameters are the same as a wxWidgets constructor.
        \param parent The parent window.
        \param id The id of the progress_listbox. Will usually be -1 unless multiple
            of them on the same dialog.
        \param pos The pixel position of the listctrl on its parent window
        \param size The pixel size of the listctrl
        \param style Style of the listbox. See wxWidgets wxListBox docs for details.
        \param validator Window validator. See wxWidgets docs for details.
        \param name Windows name (rarely used).
        \param exclusion_column_caption The label of header of listctrl's exclusion
            column.
