Class Description

                                                                      
 TGFrame, TGCompositeFrame, TGVerticalFrame, TGHorizontalFrame,       
 TGMainFrame, TGTransientFrame and TGGroupFrame                       
                                                                      
 The frame classes describe the different "dressed" GUI windows.      
                                                                      
 The TGFrame class is 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                                                  
                                                                      
 The TGCompositeFrame class is the base class for composite widgets   
 (menu bars, list boxes, etc.).                                       
 It provides:                                                         
  - a layout manager                                                  
  - a frame container (TList *)                                       
                                                                      
 The TGVerticalFrame and TGHorizontalFrame are composite frame that   
 layout their cildren in vertical or horizontal way.                  
                                                                      
 The TGMainFrame class defines top level windows that interact with   
 the system Window Manager.                                           
                                                                      
 The TGTransientFrame class defines transient windows that typically  
 are used for dialogs windows.                                        
                                                                      
 The TGGroupFrame is a composite frame with a border and a title.     
 It is typically used to group a number of logically related widgets  
 visually together.

TGCompositeFrame(const TGWindow *p, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGFrame(p, w, h, options, back)
 Create a composite frame. A composite frame has in addition to a TGFrame
 also a layout manager and a list of child frames.

TGCompositeFrame(TGClient *c, Window_t id, const TGWindow *parent) : TGFrame(c, id, parent)
 Create a frame using an externally created window. For example
 to register the root window (called by TGClient), or a window
 created via TVirtualX::InitWindow() (id is obtained with TVirtualX::GetWindowID()).

~TGCompositeFrame()
 Delete a composite frame.

void Cleanup()
 Cleanup and delete all objects contained in this composite frame.
 This will delete all objects added via AddFrame().
 CAUTION: all objects (frames and layouthints) must be unique, i.e.
 cannot be shared.

void SetLayoutManager(TGLayoutManager *l)
 Set the layout manager for the composite frame.
 The layout manager is adopted by the frame and will be deleted
 by the frame.

void ChangeOptions(UInt_t options)
 Change composite frame options. Options is an OR of the EFrameTypes.

void AddFrame(TGFrame *f, TGLayoutHints *l)
 Add frame to the composite frame using the specified layout hints.
 If no hints are specified default hints TGLayoutHints(kLHintsNormal,0,0,0,0)
 will be used. Most of the time, however, you will want to provide
 specific hints. User specified hints can be reused many times
 and need to be destoyed by the user. The added frames cannot not be
 added to different composite frames but still need to be deleted by
 the user.

void RemoveFrame(TGFrame *f)
 Remove frame from composite frame.

void MapSubwindows()
 Map all sub windows that are part of the composite frame.

void HideFrame(TGFrame *f)
 Hide sub frame.

void ShowFrame(TGFrame *f)
 Show sub frame.

Int_t GetState(TGFrame *f) const
 Get state of sub frame.

Bool_t IsVisible(TGFrame *f) const
 Get state of sub frame.

Bool_t IsArranged(TGFrame *f) const
 Get state of sub frame.

void Layout()
 Layout the elements of the composite frame.

TGFrame* GetFrameFromPoint(Int_t x, Int_t y)
 Get frame located at specified point.

Bool_t TranslateCoordinates(TGFrame *child, Int_t x, Int_t y, Int_t &fx, Int_t &fy)
 Translate coordinates to child frame.
