 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.                            
                                                                      

 Create a popup menu.

 Delete a popup menu.

 Add a menu entry. The hotstring is adopted by the menu (actually by
 the TGMenuEntry) and deleted when possible. A possible picture is
 borrowed from the picture pool and therefore not adopted.
 If before is not 0, the entry will be added before it.

 Add a menu entry. The string s in not adopted.
 If before is not 0, the entry will be added before it.

 Add a menu separator to the menu.
 If before is not 0, the entry will be added before it.

 Add a menu label to the menu. The hotstring is adopted by the menu
 (actually by the TGMenuEntry) and deleted when possible. A possible
 picture is borrowed from the picture pool and therefore not adopted.
 If before is not 0, the entry will be added before it.

 Add a menu label to the menu. The string s in not adopted.
 If before is not 0, the entry will be added before it.

 Add a (cascading) popup menu to a popup menu. The hotstring is adopted
 by the menu (actually by the TGMenuEntry) and deleted when possible.
 If before is not 0, the entry will be added before it.

 Add a (cascading) popup menu to a popup menu. The string s is not
 adopted. If before is not 0, the entry will be added before it.

 Reposition entries in popup menu. Called after menu item has been
 hidden or removed or inserted at a specified location.

 Popup a popup menu. If stick mode is true keep the menu up. If
 grab_pointer is true the pointer will be grabbed, which means that
 all pointer events will go to the popup menu, independent of in
 which window the pointer is.

 Close menu and return ID of selected menu item.
 In case of cascading menus, recursively close all menus.

 Handle button event in the popup menu.

 Handle pointer crossing event in popup menu.

 Handle pointer motion event in popup menu.

 Activate a menu entry in a popup menu.

 If TPopupDelayTimer times out popup cascading popup menu (if it is
 still the current entry).

 Draw popup menu.

 Draw popup menu entry.

 Draw border round popup menu.

 Draw triangle pattern. Used for menu entries that are of type
 kMenuPopup (i.e. cascading menus).

 Draw check mark. Used for checked button type menu entries.

 Draw radio check mark. Used for radio button type menu entries.

 Set default entry (default entries are drawn with bold text).

 Enable entry. By default entries are enabled.

 Disable entry (disabled entries appear in a sunken relieve).

 Return true if menu entry is enabled.

 Hide entry (hidden entries are not shown in the menu).
 To enable a hidden entry call EnableEntry().

 Return true if menu entry is hidden.

 Check a menu entry (i.e. add a check mark in front of it).

 Uncheck menu entry (i.e. remove check mark).

 Return true if menu item is checked.

 Radio-select entry (note that they cannot be unselected,
 the selection must be moved to another entry instead).

 Return true if menu item has radio check mark.

 Find entry with specified id. Use the returned entry in DeleteEntry()
 or as the "before" item in the AddXXXX() methods. Returns 0 if entry
 is not found. To find entries that don't have an id like the separators,
 use the GetListOfEntries() method to get the complete entry
 list and iterate over it and check the type of each entry
 to find the separators.

 Find entry with specified name. Name must match the original
 name without hot key symbol, like "Print" and not "&Print".
 Use the returned entry in DeleteEntry() or as the "before" item
 in the AddXXXX() methods. Returns 0 if entry is not found.
 To find entries that don't have a name like the separators,
 use the GetListOfEntries() method to get the complete entry
 list and iterate over it and check the type of each entry
 to find the separators.

 Delete entry with specified id from menu.

 Delete specified entry from menu.
