Detailed Description

A menu is a popup (or pull down) list of items, one of which may be selected before the menu goes away (clicking elsewhere dismisses the menu).

Menus may be used to construct either menu bars or popup menus.

A menu item has an integer ID associated with it which can be used to identify the selection, or to change the menu item in some way. A menu item with a special identifier wxID_SEPARATOR is a separator item and doesn't have an associated command but just makes a separator line appear in the menu.

Note
Please note that wxID_ABOUT and wxID_EXIT are predefined by wxWidgets and have a special meaning since entries using these IDs will be taken out of the normal menus under OS X and will be inserted into the system menu (following the appropriate OS X interface guideline).

Menu items may be either normal items, check items or radio items. Normal items don't have any special properties while the check items have a boolean flag associated to them and they show a checkmark in the menu when the flag is set. wxWidgets automatically toggles the flag value when the item is clicked and its value may be retrieved using either wxMenu::IsChecked method of wxMenu or wxMenuBar itself or by using wxEvent::IsChecked when you get the menu notification for the item in question.

The radio items are similar to the check items except that all the other items in the same radio group are unchecked when a radio item is checked. The radio group is formed by a contiguous range of radio items, i.e. it starts at the first item of this kind and ends with the first item of a different kind (or the end of the menu). Notice that because the radio groups are defined in terms of the item positions inserting or removing the items in the menu containing the radio items risks to not work correctly.

Allocation strategy

All menus must be created on the heap because all menus attached to a menubar or to another menu will be deleted by their parent when it is deleted. The only exception to this rule are the popup menus (i.e. menus used with wxWindow::PopupMenu()) as wxWidgets does not destroy them to allow reusing the same menu more than once. But the exception applies only to the menus themselves and not to any submenus of popup menus which are still destroyed by wxWidgets as usual and so must be heap-allocated.

As the frame menubar is deleted by the frame itself, it means that normally all menus used are deleted automatically.

Event handling

If the menu is part of a menubar, then wxMenuBar event processing is used.

With a popup menu (see wxWindow::PopupMenu), there is a variety of ways to handle a menu selection event (wxEVT_MENU):

  • Provide EVT_MENU handlers in the window which pops up the menu, or in an ancestor of that window (the simplest method);
  • Derive a new class from wxMenu and define event table entries using the EVT_MENU macro;
  • Set a new event handler for wxMenu, through wxEvtHandler::SetNextHandler, specifying an object whose class has EVT_MENU entries;

Note that instead of static EVT_MENU macros you can also use dynamic connection; see Dynamic Event Handling.

Constructor & Destructor Documentation

wxMenu::wxMenu ( )

Constructs a wxMenu object.

wxMenu::wxMenu ( long  style)

Constructs a wxMenu object.

Parameters
styleIf set to wxMENU_TEAROFF, the menu will be detachable (wxGTK only).
wxMenu::wxMenu ( const wxString title,
long  style = 0 
)

Constructs a wxMenu object with a title.

Parameters
titleTitle at the top of the menu (not always supported).
styleIf set to wxMENU_TEAROFF, the menu will be detachable (wxGTK only).
virtual wxMenu::~wxMenu ( )
virtual

Destructor, destroying the menu.

Note
Under Motif, a popup menu must have a valid parent (the window it was last popped up on) when being destroyed. Therefore, make sure you delete or re-use the popup menu before destroying the parent window. Re-use in this context means popping up the menu on a different window from last time, which causes an implicit destruction and recreation of internal data structures.

Member Function Documentation

wxMenuItem* wxMenu::Append ( int  id,
const wxString item = wxEmptyString,
const wxString helpString = wxEmptyString,
wxItemKind  kind = wxITEM_NORMAL 
)

Adds a menu item.

Parameters
idThe menu command identifier.
itemThe string to appear on the menu item. See wxMenuItem::SetItemLabel() for more details.
helpStringAn optional help string associated with the item. By default, the handler for the wxEVT_MENU_HIGHLIGHT event displays this string in the status line.
kindMay be wxITEM_SEPARATOR, wxITEM_NORMAL, wxITEM_CHECK or wxITEM_RADIO.

Example:

m_pFileMenu->Append(ID_NEW_FILE, "&New file\tCTRL+N", "Creates a new XYZ document");

or even better for stock menu items (see wxMenuItem::wxMenuItem):

m_pFileMenu->Append(wxID_NEW, "", "Creates a new XYZ document");
Remarks
This command can be used after the menu has been shown, as well as on initial creation of a menu or menubar.

wxMenuItem* wxMenu::Append ( int  id,
const wxString item,
wxMenu subMenu,
const wxString helpString = wxEmptyString 
)

Adds a submenu.

Deprecated:
This function is deprecated, use AppendSubMenu() instead.
Parameters
idThe menu command identifier.
itemThe string to appear on the menu item.
subMenuPull-right submenu.
helpStringAn optional help string associated with the item. By default, the handler for the wxEVT_MENU_HIGHLIGHT event displays this string in the status line.

AppendSeparator(), AppendCheckItem(), AppendRadioItem(), AppendSubMenu(), Insert(), SetLabel(), GetHelpString(), SetHelpString(), wxMenuItem
wxMenuItem* wxMenu::Append ( wxMenuItem menuItem)

Adds a menu item object.

This is the most generic variant of Append() method because it may be used for both items (including separators) and submenus and because you can also specify various extra properties of a menu item this way, such as bitmaps and fonts.

Parameters
menuItemA menuitem object. It will be owned by the wxMenu object after this function is called, so do not delete it yourself.
Remarks
See the remarks for the other Append() overloads.
