NAME

EvtHandler::DoCreateMenu - instance method

TEMPLATE

void DoCreateMenu(Menu * menu)

SPECIFIERS

public virtual

DESCRIPTION

DoCreateMenu is called by the method VObject::DoRightButtonDownCommand once for each new popup menu before the menu is shown the first time.
Overriding DoCreateMenu gives the possibility to add new menu items or whole submenus to the menu. A typical implementation first calls the inherited method to allow the base classes and next handlers to add their menu items. Then this handler adds its own items as the following example shows:

void MyClass::DoCreateMenu (Menu *menu)
{
    MyBaseClass::DoCreateMenu(menu);
    menu->AppendItem ("menu command 1", cMENUCMD1);
    menu->AppendItems ("-",
                        "menu command 2", cMENUCMD2,
                        NULL);
}

The default implementation forwards DoCreateMenu to the next handler.
See also class Menu, method GetMenu, method DoSetupMenu and method DoMenuCommand. Method is often overridden.

ARGUMENTS

Menu * menu: a new menu returned by the method GetMenu to be filled with menu items
