phoenix_title MenuItem

A menu item represents an item in a menu.

Note that you usually don’t have to deal with it directly as Menu methods usually construct an object of this class for you.

Also please note that the methods related to fonts and bitmaps are currently only implemented for Windows, Mac and GTK+.

events Events Emitted by this Class

Handlers bound for the following event types will receive one of the CommandEvent MenuEvent parameters.

  • EVT_MENU: Process a wxEVT_COMMAND_MENU_SELECTED command, which is generated by a menu item. This type of event is sent as CommandEvent.
  • EVT_MENU_RANGE: Process a wxEVT_COMMAND_MENU_RANGE command, which is generated by a range of menu items. This type of event is sent as CommandEvent.
  • EVT_MENU_OPEN: A menu is about to be opened. On Windows, this is only sent once for each navigation of the menubar (up until all menus have closed). This type of event is sent as MenuEvent.
  • EVT_MENU_CLOSE: A menu has been just closed. This type of event is sent as MenuEvent.
  • EVT_MENU_HIGHLIGHT: The menu item with the specified id has been highlighted: used to show help prompts in the status bar by Frame This type of event is sent as MenuEvent.
  • EVT_MENU_HIGHLIGHT_ALL: A menu item has been highlighted, i.e. the currently selected menu item has changed. This type of event is sent as MenuEvent.

api Class API



A menu item represents an item in a menu.

Possible constructors:

MenuItem(parentMenu=None, id=ID_SEPARATOR, text='',
         helpString='', kind=ITEM_NORMAL, subMenu=None)

Methods



Constructs a MenuItem object.

Menu items can be standard, or “stock menu items”, or custom. For the standard menu items (such as commands to open a file, exit the program and so on, see Stock items for the full list) it is enough to specify just the stock ID and leave text and helpString empty. Some platforms (currently wxGTK only, and see the remark in SetBitmap documentation) will also show standard bitmaps for stock menu items.

Leaving at least text empty for the stock menu items is actually strongly recommended as they will have appearance and keyboard interface (including standard accelerators) familiar to the user.

For the custom (non-stock) menu items, text must be specified and while helpString may be left empty, it’s recommended to pass the item description (which is automatically shown by the library in the status bar when the menu item is selected) in this parameter.

Finally note that you can e.g. use a stock menu label without using its stock help string:

# use all stock properties:
helpMenu.Append(wx.ID_ABOUT)

# use the stock label and the stock accelerator but not the stock help string:
helpMenu.Append(wx.ID_ABOUT, "", "My custom help string")

# use all stock properties except for the bitmap:
mymenu = wx.MenuItem(helpMenu, wx.ID_ABOUT)
mymenu.SetBitmap(wx.ArtProvider.GetBitmap(wx.ART_WARNING))
helpMenu.Append(mymenu)

that is, stock properties are set independently one from the other.

Parameters:
  • parentMenu (Menu) – Menu that the menu item belongs to. Can be None if the item is going to be added to the menu later.
  • id (int) – Identifier for this menu item. May be ID_SEPARATOR , in which case the given kind is ignored and taken to be ITEM_SEPARATOR instead.
  • text (string) – Text for the menu item, as shown on the menu. See SetItemLabel for more info.
  • helpString (string) – Optional help string that will be shown on the status bar.
  • kind (ItemKind) – May be ITEM_SEPARATOR , ITEM_NORMAL , ITEM_CHECK or ITEM_RADIO .
  • subMenu (Menu) – If not None, indicates that the menu item is a submenu.


Checks or unchecks the menu item.

Note that this only works when the item is already appended to a menu.

will return just "Hello" .

Availability

Sets the bitmap for the menu item.

It is equivalent to MenuItem.SetBitmaps(bmp, NullBitmap) if checked is True (default value) or SetBitmaps(wxNullBitmap, bmp) otherwise.

Notice that GTK+ uses a global setting called gtk-menu-images to determine if the images should be shown in the menus at all. If it is off (which is the case in e.g. Gnome 2.28 by default), no images will be shown, consistently with the native behaviour.

Parameters:
  • bmp (Bitmap) –
  • checked (bool) –

Availability

Only available for MSW, OSX, GTK.



Sets the checked/unchecked bitmaps for the menu item.

The first bitmap is also used as the single bitmap for uncheckable menu items.

Parameters:

Availability

Only available for MSW.



Sets the font associated with the menu item.

Parameters:font (Font) –

Availability

Only available for MSW.



Sets the help string.

Parameters:helpString (string) –


Sets the label associated with the menu item.

Note that if the ID of this menu item corresponds to a stock ID, then it is not necessary to specify a label: wxWidgets will automatically use the stock item label associated with that ID. See the constructor for more info.

The label string for the normal menu items (not separators) may include the accelerator which can be used to activate the menu item from keyboard. An accelerator key can be specified using the ampersand & character. In order to embed an ampersand character in the menu item text, the ampersand must be doubled.

Optionally you can specify also an accelerator string appending a tab character \t followed by a valid key combination (e.g. CTRL+V ). Its general syntax is any combination of "CTRL" , "RAWCTRL" , "ALT" and "SHIFT" strings (case doesn’t matter) separated by either '-' or '+' characters and followed by the accelerator itself. Notice that CTRL corresponds to the “Ctrl” key on most platforms but not under Mac OS where it is mapped to “Cmd” key on Mac keyboard. Usually this is exactly what you want in portable code but if you really need to use the (rarely used for this purpose) “Ctrl” key even under Mac, you may use RAWCTRL to prevent this mapping. Under the other platforms RAWCTRL is the same as plain CTRL .

The accelerator may be any alphanumeric character, any function key (from F1 to F12) or one of the special characters listed in the table below (again, case doesn’t matter):

  • DEL or DELETE: Delete key
  • BACK : Backspace key
  • INS or INSERT: Insert key
  • ENTER or RETURN: Enter key
  • PGUP: PageUp key
  • PGDN: PageDown key
  • LEFT: Left cursor arrow key
  • RIGHT: Right cursor arrow key
  • UP: Up cursor arrow key
  • DOWN: Down cursor arrow key
  • HOME: Home key
  • END: End key
  • SPACE: Space
  • TAB: Tab key
  • ESC or ESCAPE: Escape key (Windows only)

Examples:

self.myMenuItem.SetItemLabel("My &item\tCTRL+I")
self.myMenuItem2.SetItemLabel("Clean and build\tF7")
self.myMenuItem3.SetItemLabel("Simple item")
self.myMenuItem4.SetItemLabel("Item with &accelerator")
