@class wxMessageDialog
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. May be combined with
@c wxCANCEL.
@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_EXCLAMATION}
Displays an exclamation mark symbol.
@style{wxICON_ERROR}
Displays an error symbol.
@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.
@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 (currently
implemented only under MSW).

Notice that not all styles are compatible: only one of @c wxOK and

corresponding button is shown in the message box.

Overrides the default labels of the Yes and No buttons.
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 (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.:
@code
wxMessageDialog dlg(...);
if ( dlg.SetYesNoLabels(_("&Quit"), _("&Don't quit")) )
dlg.SetMessage(_("What do you want to do?"));
else // buttons have standard "Yes"/"No" values, so rephrase the question
dlg.SetMessage(_("Do you really want to quit?"));
@endcode

Notice that this method returns the identifier of the button which was
clicked unlike wxMessageBox() function.

/**
Show a general purpose message dialog.
This is a convenient function which is usually used instead of using
wxMessageDialog directly. Notice however that some of the features, such as
extended text and custom labels for the message box buttons, are not
provided by this function but only by wxMessageDialog.
The return value is one of: @c wxYES, @c wxNO, @c wxCANCEL or @c wxOK
(notice that this return value is @b different from the return value of
wxMessageDialog::ShowModal()).
For example:
@code
int answer = wxMessageBox("Quit program?", "Confirm",
wxYES_NO | wxCANCEL, main_frame);
if (answer == wxYES)
main_frame->Close();
@endcode
@a message may contain newline characters, in which case the message will
be split into separate lines, to cater for large messages.
@param message
Message to show in the dialog.
@param caption
The dialog title.
@param parent
Parent window.
@param style
Combination of style flags described in wxMessageDialog documentation.
@param x
Horizontal dialog position (ignored under MSW). Use ::wxDefaultCoord
for @a x and @a y to let the system position the window.
@param y
Vertical dialog position (ignored under MSW).
