Class Description

                                                                      
 TGMenuBar, TGPopupMenu, TGMenuTitle and TGMenuEntry                  
                                                                      
 This header contains all different menu classes.                     
                                                                      
 Selecting a menu item will generate the event:                       
 kC_COMMAND, kCM_MENU, menu id, user data.                            
                                                                      


TGMenuBar(const TGWindow *p, UInt_t w, UInt_t h, UInt_t options) : TGHorizontalFrame(p, w, h, options | kHorizontalFrame)
 Create a menu bar object.

~TGMenuBar()
 Delete menu bar object. Removes also the hot keys from the main frame,
 so hitting them will not cause the menus to popup.

void BindKeys(Bool_t on)
 If on kTRUE bind arrow, popup menu hot keys, otherwise
 remove key bindings.

void BindHotKey(Int_t keycode, Bool_t on)
 If on kTRUE bind hot keys, otherwise remove key binding.

void AddPopup(TGHotString *s, TGPopupMenu *menu, TGLayoutHints *l, TGPopupMenu *before)
 Add popup menu to menu bar. The hot string will be adopted by the
 menubar (actually the menu title) and deleted when possible.
 If before is not 0 the menu will be added before it.

void AddPopup(const char *s, TGPopupMenu *menu, TGLayoutHints *l, TGPopupMenu *before)
 Add popup menu to menu bar. If before is not 0 the menu will be
 added before it.

TGPopupMenu* AddPopup(const TString &s, Int_t padleft, Int_t padright, Int_t padtop, Int_t padbottom)
 Add popup menu to menu bar.

 Comment:
    This method is valid  only for horizontal menu bars.
    The most common case is menu bar containing equidistant titles padding left side.
       TGMenuBar *bar;
       bar->AddPopup("title1", 10);
       bar->AddPopup("title2", 10);
       ...

    To add equidistant titles  padding right side padleft must be 0.
       TGMenuBar *bar;
       bar->AddPopup("title1", 0, 10);
       bar->AddPopup("title2", 0, 10);
       ...

    This method guarantee automatic cleanup when menu bar is destroyed.
    Do not delete returned popup-menu

void AddFrameBefore(TGFrame *f, TGLayoutHints *l, TGPopupMenu *before)
 Private version of AddFrame for menubar, to make sure that we
 indeed only add TGMenuTitle objects to it. If before is not 0
 the menu will be added before it.

TGPopupMenu* GetPopup(const char *s)
 Return popup menu with the specified name. Returns 0 if menu is
 not found. Returnes menu can be used as "before" in AddPopup().
 Don't use hot key (&) in name.

TGPopupMenu* RemovePopup(const char *s)
 Remove popup menu from menu bar. Returned menu has to be deleted by
 the user, or can be re-used in another AddPopup(). Returns 0 if
 menu is not found. Don't use hot key (&) in name.

Bool_t HandleMotion(Event_t *event)
 Handle a mouse motion event in a menu bar.

Bool_t HandleButton(Event_t *event)
 Handle a mouse button event in a menubar.

Bool_t HandleKey(Event_t *event)
 Handle keyboard events in a menu bar.

void SavePrimitive(ofstream &out, Option_t *option)
 Save a menu bar widget as a C++ statement(s) on output stream out.
