    @class wxAboutDialogInfo

    wxAboutDialogInfo contains information shown in the standard @e About
    dialog displayed by the wxAboutBox() function.

    This class contains the general information about the program, such as its
    name, version, copyright and so on, as well as lists of the program developers,
    documentation writers, artists and translators. The simple properties from the
    former group are represented as a string with the exception of the program icon
    and the program web site, while the lists from the latter group are stored as
    wxArrayString and can be either set entirely at once using
    wxAboutDialogInfo::SetDevelopers and similar functions or built one by one using
    wxAboutDialogInfo::AddDeveloper etc.

    Please also notice that while all the main platforms have the native
    implementation of the about dialog, they are often more limited than the
    generic version provided by wxWidgets and so the generic version is used if
    wxAboutDialogInfo has any fields not supported by the native version. Currently
    GTK+ version supports all the possible fields natively but MSW and Mac versions
    don't support URLs, licence text nor custom icons in the about dialog and if
    either of those is used, wxAboutBox() will automatically use the generic version
    so you should avoid specifying these fields to achieve more native look and feel.
    
    Example of usage:
    @code
    void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
    {
        wxAboutDialogInfo aboutInfo;
        aboutInfo.SetName("MyApp");
        aboutInfo.SetVersion(MY_APP_VERSION_STRING);
        aboutInfo.SetDescription(_("My wxWidgets-based application!"));
        aboutInfo.SetCopyright("(C) 1992-2010");
        aboutInfo.SetWebSite("http://myapp.org");
        aboutInfo.AddDeveloper("My Self");

        wxAboutBox(aboutInfo);
    }

/**
    This function shows the standard about dialog containing the information
    specified in @a info. If the current platform has a native about dialog
    which is capable of showing all the fields in @a info, the native dialog is
    used, otherwise the function falls back to the generic wxWidgets version of
    the dialog, i.e. does the same thing as wxGenericAboutBox.

    Here is an example of how this function may be used:

    @code
    void MyFrame::ShowSimpleAboutDialog(wxCommandEvent& WXUNUSED(event))
    {
        wxAboutDialogInfo info;
        info.SetName(_("My Program"));

        info.SetDescription(_("This program does something great."));
        info.SetCopyright(wxT("(C) 2007 Me <my@email.addre.ss>"));

        wxAboutBox(info);
    }
    @endcode

    Please see the @ref page_samples_dialogs for more examples of using this
    function and wxAboutDialogInfo for the description of the information which
    can be shown in the about dialog.
