The GnomeMessageBox widget creates dialog boxes (of type
GnomeDialog) that contain a severity level (indicated by an icon
and a title), a message to be displayed and a list of buttons that
will be in the dialog.
The programmer will use strings desired for each button. If the
strings are any of the GNOME_STOCK macros, then instead of creating
a button with the text, the button will be a GNOME stock button
with a stock icon.
The list of known types for message boxes are:
GNOME_MESSAGE_BOX_ERROR, GNOME_MESSAGE_BOX_GENERIC, GNOME_MESSAGE_BOX_INFO, GNOME_MESSAGE_BOX_QUESTION and GNOME_MESSAGE_BOX_WARNING.
Gnome.MessageBox( "This is a nice message", Gnome.MessageBoxInfo, Gnome.StockButtonOk, Gnome.StockButtonCancel );
Gnome.MessageBox( "This is another not so nice message", Gnome.MessageBoxError, Gnome.StockButtonClose, Gnome.StockButtonCancel );
