toolkit constructor for ggroup

  ## S3 method for class 'guiWidgetsToolkitQt'
 .ggroup(toolkit,
    horizontal = TRUE, spacing = 5,
    use.scrollwindow = FALSE, container = NULL, ...)

`toolkit`	Each widget constructor is passed in the toolkit it will use. This is typically done using the default, which will lookup the toolkit through `guiToolkit`.
`horizontal`	logical. If TRUE, left to right layout, otherwise top to bottom
`spacing`	spacing aroud widget
`use.scrollwindow`	logical. If TRUE, places box container in scrollwindow. In this case, a size should be set.
`container`	A parent container. When a widget is created it can be incorporated into the widget heirarchy by passing in a parent container at construction time. (For some toolkits this is not optional, e.g. gWidgets2tcltk or gWidgets2WWW2.)
`...`	These values are passed to the `add` method of the parent container, and occasionally have been used to sneak in hidden arguments to toolkit implementations. For example, when using a widget as a menubar object one can specify a parent argument to pass in parent information, similar to how the argument is used with gaction and the dialogs.
