/** @class wxPropertyGrid

    wxPropertyGrid is a specialized grid for editing properties
    such as strings, numbers, flagsets, fonts, and colours. wxPropertySheet
    used to do the very same thing, but it hasn't been updated for a while
    and it is currently deprecated.

    Please note that most member functions are inherited and as such not
    documented on this page. This means you will probably also want to read
    wxPropertyGridInterface class reference.

    See also @ref overview_propgrid.

    @section propgrid_window_styles_ Window Styles

    See @ref propgrid_window_styles.

    @section propgrid_event_handling Event Handling

    To process input from a propertygrid control, use these event handler
    macros to direct input to member functions that take a wxPropertyGridEvent
    argument.

    @beginEventTable{wxPropertyGridEvent}
    @event{EVT_PG_SELECTED (id, func)}
        Respond to wxEVT_PG_SELECTED event, generated when a property selection
        has been changed, either by user action or by indirect program
        function. For instance, collapsing a parent property programmatically
        causes any selected child property to become unselected, and may
        therefore cause this event to be generated.
    @event{EVT_PG_CHANGING(id, func)}
        Respond to wxEVT_PG_CHANGING event, generated when property value
        is about to be changed by user. Use wxPropertyGridEvent::GetValue()
        to take a peek at the pending value, and wxPropertyGridEvent::Veto()
        to prevent change from taking place, if necessary.
    @event{EVT_PG_HIGHLIGHTED(id, func)}
        Respond to wxEVT_PG_HIGHLIGHTED event, which occurs when mouse
        moves over a property. Event's property is NULL if hovered area does
        not belong to any property.
    @event{EVT_PG_RIGHT_CLICK(id, func)}
        Respond to wxEVT_PG_RIGHT_CLICK event, which occurs when property is
