/** \class TGFrame
    \ingroup guiwidgets
 
A subclasses of TGWindow, and is used as base
class for some simple widgets (buttons, labels, etc.).
It provides:
 - position & dimension fields
 - an 'options' attribute (see constant above)
 - a generic event handler
 - a generic layout mechanism
 - a generic border
 
 
\class TGCompositeFrame
\ingroup guiwidgets
 
The base class for composite widgets
(menu bars, list boxes, etc.).
It provides:
 - a layout manager
 - a frame container (TList *)
 
 
\class TGVerticalFrame
\ingroup guiwidgets
A composite frame that layout their children in vertical  way.
 
 
\class TGHorizontalFrame
\ingroup guiwidgets
A composite frame that layout their children in  horizontal way.
 
 
\class TGMainFrame
\ingroup guiwidgets
Defines top level windows that interact with the system Window Manager.
 
 
\class TGTransientFrame
\ingroup guiwidgets
Defines transient windows that typically are used for dialogs windows.
 
 
\class TGGroupFrame
\ingroup guiwidgets
A composite frame with a border and a title.
It is typically used to group a number of logically related widgets visually together.
 
\class TGHeaderFrame
\ingroup guiwidgets
Horizontal Frame used to contain header buttons and splitters
in a list view. Used to have resizable column headers.
