class TGMenuBar: public TGHorizontalFrame


TGMenuBar, TGPopupMenu, TGMenuTitle and TGMenuEntry

The TGMenu.h header contains all different menu classes.

The TGMenuBar class implements a menu bar widget. It is used to
specify and provide access to common and frequently used application
actions grouped under menu titles (TGMenuTitle class). The menu bar
takes the highest-level of the menu system and it is a starting
point for many interactions. It is always visible and allows using
the keyboard equivalents. The geometry of the menu bar is
automatically set to the parent widget, i.e. the menu bar
automatically resizes itself so that it has the same width as its
parent (typically TGMainFrame). A menu bar contains one or more
popup menus and usually is placed along the top of the application
window. Any popup menu is invisible until the user invokes it by
using the mouse pointer or the keyboard.

Popup menus implemented by TGPopupMenu class are unique in that,
by convention, they are not placed with the other GUI components in
the user interfaces. Instead, a popup menu usually appears either in
a menu bar or as a context menu on the TOP of the GUI. For that
reason it needs gClient->GetDefaultRoot() as a parent to get the
pointer to the root (i.e. desktop) window. This way a popup menu
will never be embedded.
NOTE: Using gClient->GetRoot() as a parent of TGPopupMenu will not
avoid the possibility of embedding the corresponding popup menu
because the current window hierarchy can be changed by using
gClient->SetRoot() method.

As a context menus TGPopupMenu shows up after pressing the right
mouse button, over a popup-enabled component. The popup menu then
appears under the mouse pointer.

Selecting a menu item will generate the event:
kC_COMMAND, kCM_MENU, menu id, user data.

Function documentation

TGMenuBar(const TGWindow* p = 0, UInt_t w = 60, UInt_t h = 20, UInt_t options = kHorizontalFrame|kRaisedFrame)
 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 Layout()
 Clculates whether the >> menu must be shown or not and
 which menu titles are hidden.
TGFrameElement* GetLastOnLeft()
 Returns the last visible menu title on the left of the '>>'
 in the menu bar.
void PopupConnection()
 Connects the corresponding cascaded menu to the proper slots,
 according to the highlighted menu entry in '>>' menu.
void BindKeys(Bool_t on = kTRUE)
 If on kTRUE bind arrow, popup menu hot keys, otherwise
 remove key bindings.
void BindMenu(TGPopupMenu* subMenu, Bool_t on)
 If on kTRUE bind subMenu hot keys, otherwise remove key bindings.
void BindHotKey(Int_t keycode, Bool_t on = kTRUE)
 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 AddTitle(TGMenuTitle* title, TGLayoutHints* l, TGPopupMenu* before = 0)
 Add popup via created before menu title.
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 = 4, Int_t padright = 0, Int_t padtop = 0, Int_t padbottom = 0)
 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 = 0, TGPopupMenu* before = 0)
 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(ostream& out, Option_t* option = "")
 Save a menu bar widget as a C++ statement(s) on output stream out.
TGMenuEntry& operator=(const TGMenuBar& )
TGMenuEntry * GetCurrent() const
{ return fCurrent; }
TGMenuBar(const TGMenuBar& )
TList * GetTitles() const
{ return fTitles; }
