    // along with which line you if was created, but you forget to free the memory.

    // default value for all parameters in your constructor, or else having a dummy
    // MyResizableListCtrl(){} constructor in addition to your regular one.

        These parameters are the same as a wxWindows 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 wxWindows wxListBox docs for details.
        \param validator Window validator. See wxWindows docs for details.
        \param name Windows name (rarely used).
        \param exclusion_column_caption The label of header of listctrl's exclusion
            column.
