## 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 children 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.

Bool_t IsEditable() const

     Return kTRUE if frame is being edited.

void SetEditable(Bool_t on)

     Switch ON/OFF edit mode.
     If edit mode is ON it is possible:

      1. embed other ROOT GUI application (a la ActiveX)

      For example:
        TGMainFrame *m = new TGMainFrame(gClient->GetRoot(), 500, 500);
        m->SetEditable();
        gSystem->Load("$ROOTSYS/test/Aclock"); // load Aclock demo
        Aclock a;
        gROOT->Macro("$ROOTSYS/tutorials/guitest.C");
        m->SetEditable(0);
        m->MapWindow();

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 layout hints) 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 SetLayoutBroken(Bool_t on)

     Set broken layout. No Layout method is called.

void SetEditDisabled(Bool_t on)

      disable/enable edit this frame and all subframes

void ChangeOptions(UInt_t options)

     Change composite frame options. Options is an OR of the EFrameTypes.

void SetCleanup(Int_t mode)

     Turn on automatic cleanup of child frames in dtor.

     if mode = kNoCleanup    - no automatic cleanup
     if mode = kLocalCleanup - automatic cleanup in this composite frame only
     if mode = kDeepCleanup  - automatic deep cleanup in this composite frame
                               and all child composite frames (hierarchical)

     Attention!
        Hierarchical cleaning is dangerous and must be used with caution.
        There are many GUI components (in ROOT and in user code) which do not
        use Clean method in destructor ("custom deallocation").
        Adding such component to GUI container which is using hierarchical
        cleaning will produce seg. violation when container is deleted.
        The reason is double deletion: first whem Clean method is invoked,
        then at "custom deallocation".
        We are going to correct all ROOT code to make it to be
        consitent with hierarchical cleaning scheeme.

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 destroyed 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.

void Print(Option_t *option) const

     Print all frames in this 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.

Bool_t HandleDragEnter(TGFrame *)

     Handle drag enter event.

Bool_t HandleDragLeave(TGFrame *)

     Handle drag leave event.

Bool_t HandleDragMotion(TGFrame *)

     Handle drag motion event.

Bool_t HandleDragDrop(TGFrame *frame, Int_t x, Int_t y, TGLayoutHints *lo)

     Handle drop event.

void SavePrimitiveSubframes(ofstream &out, Option_t *option)

     auxilary protected method  used to save subframes

void SavePrimitive(ofstream &out, Option_t *option)

     Save a composite frame widget as a C++ statement(s) on output stream out
