         "It provides some standards buttons that are needed in most dialogs. Each one may be "
         "hidden, enabled or disabled, and tooltips and quickhelp texts might be"
         " added. And you do not need to bother about geometry management, this "
         "is all done automatically.<br>"
         "The class supports the creation of dialogs without being forced "
         "to derive an own class for it, but you may derive your own class "
         "for a better code structure.<br>"
         "If you wrote a help chapter explaining what your dialog does, you "
         "should add a link to it to the dialog using <tt>setHelp</tt>. You do "

        you already have a widget class representing the core of your dialog,
        and you only need to add a frame around it and the default buttons.
