/**
This class represents a dialog that shows a single or multi-line message,
with a choice of OK, Yes, No and Cancel buttons.
+ @beginStyleTable
+ @style{wxOK}
+ Puts an Ok button in the message box. May be combined with @c wxCANCEL.
+ @style{wxCANCEL}
+ Puts a Cancel button in the message box. Must be combined with
+ either @c wxOK or @c wxYES_NO.
+ @style{wxYES_NO}
+ Puts Yes and No buttons in the message box. It is recommended to always
+ use @c wxCANCEL with this style as otherwise the message box won't have
+ a close button under wxMSW and the user will be forced to answer it.
+ @style{wxNO_DEFAULT}
+ Makes the "No" button default, can only be used with @c wxYES_NO.
+ @style{wxCANCEL_DEFAULT}
+ Makes the "Cancel" button default, can only be used with @c wxCANCEL
+ @style{wxYES_DEFAULT}
+ Makes the "Yes" button default, this is the default behaviour and
+ this flag exists solely for symmetry with @c wxNO_DEFAULT.
+ @style{wxOK_DEFAULT}
+ Makes the "OK" button default, this is the default behaviour and
+ this flag exists solely for symmetry with @c wxCANCEL_DEFAULT.
+ @style{wxICON_NONE}
+ Displays no icon in the dialog if possible (an icon might still be
+ displayed if the current platform mandates its use). This style may be
+ used to prevent the dialog from using the default icon based on @c
+ wxYES_NO presence as explained in @c wxICON_QUESTION and @c
+ wxICON_INFORMATION documentation below.
+ @style{wxICON_EXCLAMATION}
+ Displays an exclamation, or warning, icon in the dialog.
+ @style{wxICON_ERROR}
+ Displays an error icon in the dialog.
+ @style{wxICON_HAND}
+ Displays an error symbol, this is a MSW-inspired synonym for @c wxICON_ERROR.
+ @style{wxICON_QUESTION}
+ Displays a question mark symbol. This icon is automatically used
+ with @c wxYES_NO so it's usually unnecessary to specify it explicitly.
+ This style is not supported for message dialogs under wxMSW when a task
+ dialog is used to implement them (i.e. when running under Windows Vista
+ or later) because <a href="http://msdn.microsoft.com/en-us/library/aa511273.aspx">Microsoft
+ guidelines</a> indicate that no icon should be used for routine
+ confirmations. If it is specified, no icon will be displayed.
+ @style{wxICON_INFORMATION}
+ Displays an information symbol. This icon is used by default if
+ @c wxYES_NO is not given so it is usually unnecessary to specify it
+ explicitly.
+ @style{wxSTAY_ON_TOP}
+ Makes the message box stay on top of all other windows and not only
+ just its parent (currently implemented only under MSW and GTK).
+ @style{wxCENTRE}
+ Centre the message box on its parent or on the screen if parent is not
+ specified.
+ Setting this style under MSW makes no differences as the dialog is
+ always centered on the parent.

- Notice that this function is not currently available on all platforms,
- so it may return @false to indicate that the labels couldn't be
- changed. If it returns @true (currently only under wxMac), the labels
- were set successfully. Typically, if the function was used
- successfully, the main dialog message may need to be changed, e.g.:
+ The arguments of this function can be either strings or one of the
+ standard identifiers, such as @c wxID_APPLY or @c wxID_OPEN. Notice
+ that even if the label is specified as an identifier, the return value
+ of the dialog ShowModal() method still remains one of @c wxID_OK, @c
+ wxID_CANCEL, @c wxID_YES or @c wxID_NO values, i.e. this identifier
+ changes only the label appearance but not the return code generated by
+ the button. It is possible to mix stock identifiers and string labels
+ in the same function call, for example:
+ @code
+ wxMessageDialog dlg(...);
+ dlg.SetYesNoLabels(wxID_SAVE, _("&Don't save"));
+ @endcode
+
+ Also notice that this function is not currently available on all
+ platforms (although as of wxWidgets 2.9.0 it is implemented in all
+ major ports), so it may return @false to indicate that the labels
+ couldn't be changed. If it returns @true, the labels were set
+ successfully.
+
+ Typically, if the function was used successfully, the main dialog
+ message may need to be changed, e.g.:
@code
wxMessageDialog dlg(...);
if ( dlg.SetYesNoLabels(_("&Quit"), _("&Don't quit")) )
else // buttons have standard "Yes"/"No" values, so rephrase the question
dlg.SetMessage(_("Do you really want to quit?"));
