A menu item represents an item in a menu.
Note that you usually don’t have to deal with it directly as wx.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+.
^^
Handlers bound for the following event types will receive one of the wx.CommandEvent wx.MenuEvent parameters.
EVT_MENU: Process a wxEVT_MENU
command, which is generated by a menu item. This type of event is sent as wx.CommandEvent.
EVT_MENU_RANGE: Process a wxEVT_MENU
command, which is generated by a range of menu items. This type of event is sent as wx.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 wx.MenuEvent.
EVT_MENU_CLOSE: A menu has been just closed. This type of event is sent as wx.MenuEvent.
EVT_MENU_HIGHLIGHT: The menu item with the specified id has been highlighted. If the id is ID_NONE
, highlighting has been removed from the previously highlighted menu item and there is no highlighted item any more. This is used by wx.Frame to show help prompts in the status bar. This type of event is sent as wx.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 wx.MenuEvent. ^^

MenuItem
(Object)¶Possible constructors:
MenuItem(parentMenu=None, id=ID_SEPARATOR, text="",
helpString="", kind=ITEM_NORMAL, subMenu=None)
A menu item represents an item in a menu.
__init__
(self, parentMenu=None, id=ID_SEPARATOR, text="", helpString="", kind=ITEM_NORMAL, subMenu=None)¶Constructs a wx.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.
parentMenu (wx.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 (wx.Menu) – If not None
, indicates that the menu item is a submenu.
AddExtraAccel
(self, accel)¶Add an extra accelerator for this menu item.
Additional accelerators are not shown in the item’s label, but still will trigger the menu command when pressed.
They can be useful to let multiple keys be used as accelerators for the same command, e.g. WXK_ADD
and WXK_NUMPAD_ADD
.
accel (AcceleratorEntry
) –
New in version 4.1/wxWidgets-3.1.6.
Availability
Only available for MSW, GTK.
Check
(self, check=True)¶Checks or unchecks the menu item.
Note that this only works when the item is already appended to a menu.
check (bool) –
ClearExtraAccels
(self)¶Clear the extra accelerators list.
This doesn’t affect the main item accelerator (if any).
New in version 4.1/wxWidgets-3.1.6.
Enable
(self, enable=True)¶Enables or disables the menu item.
enable (bool) –
GetAccel
(self)¶Get our accelerator or None
(caller must delete the pointer)
GetBackgroundColour
(self)¶Returns the background colour associated with the menu item.
Availability
Only available for MSW.
GetBitmap
(self, *args, **kw)¶GetBitmap (self)
Returns the item bitmap.
This method exists only for compatibility, please use GetBitmapBundle
in the new code.
GetBitmap (self, checked)
Returns the checked or unchecked bitmap.
This overload only exists in wxMSW, avoid using it in portable code.
checked (bool) –
GetBitmapBundle
(self)¶Returns the bitmap bundle containing the bitmap used for this item.
The returned bundle is invalid, i.e. empty, if no bitmap is associated with the item.
New in version 4.2/wxWidgets-3.2.0.

GetDisabledBitmap
(self)¶Returns the bitmap used for disabled items.
Availability
Only available for MSW.

GetKind
(self)¶Returns the item kind, one of ITEM_SEPARATOR
, ITEM_NORMAL
, ITEM_CHECK
or ITEM_RADIO
.
GetLabelText
(text)¶Strips all accelerator characters and mnemonics from the given text.
For example:
wx.MenuItem.GetLabelfromText("&Hello\tCtrl-h")
will return just "Hello"
.
text (string) –
string

GetMarginWidth
(self)¶Gets the width of the menu item checkmark bitmap.
int
Availability
Only available for MSW.
GetMenu
(self)¶Returns the menu this menu item is in, or None
if this menu item is not attached.
GetSubMenu
(self)¶Returns the submenu associated with the menu item, or None
if there isn’t one.
GetTextColour
(self)¶Returns the text colour associated with the menu item.
Availability
Only available for MSW.
IsCheck
(self)¶Returns True
if the item is a check item.
Unlike IsCheckable
this doesn’t return True
for the radio buttons.
bool
New in version 2.9.5.
IsCheckable
(self)¶Returns True
if the item is checkable.
Notice that the radio buttons are considered to be checkable as well, so this method returns True
for them too. Use IsCheck
if you want to test for the check items only.
bool
IsChecked
(self)¶Returns True
if the item is checked.
bool
IsEnabled
(self)¶Returns True
if the item is enabled.
bool
IsRadio
(self)¶Returns True
if the item is a radio button.
bool
New in version 2.9.5.
IsSeparator
(self)¶Returns True
if the item is a separator.
bool
IsSubMenu
(self)¶Returns True
if the item is a submenu.
bool
SetAccel
(self, accel)¶Set the accel for this item - this may also be done indirectly with SetText
accel (wx.AcceleratorEntry) –
SetBackgroundColour
(self, colour)¶Sets the background colour associated with the menu item.
colour (wx.Colour) –
Availability
Only available for MSW.
SetBitmap
(self, *args, **kw)¶SetBitmap (self, bmp)
Sets the bitmap for the menu item.
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.
bmp (wx.BitmapBundle) –
SetBitmap (self, bmp, checked)
Sets the checked or unchecked bitmap for the menu item.
It is equivalent to MenuItem.SetBitmaps(bmp, NullBitmap) if checked is True
or SetBitmaps(wxNullBitmap, bmp) otherwise.
Note that different bitmaps for checked and unchecked item states are not supported in most ports, while setting just a single bitmap using the overload above is supported in all of them.
bmp (wx.BitmapBundle) –
checked (bool) –
Availability
Only available for MSW.
SetBitmaps
(self, checked, unchecked=NullBitmap)¶Sets the checked/unchecked bitmaps for the menu item.
The first bitmap is also used as the single bitmap for uncheckable menu items.
checked (wx.BitmapBundle) –
unchecked (wx.BitmapBundle) –
Availability
Only available for MSW.
SetDisabledBitmap
(self, disabled)¶Sets the to be used for disabled menu items.
disabled (wx.BitmapBundle) –
Availability
Only available for MSW.
SetFont
(self, font)¶Sets the font associated with the menu item.
font (wx.Font) –
Availability
Only available for MSW.
SetHelp
(self, helpString)¶Sets the help string.
helpString (string) –
SetItemLabel
(self, label)¶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 macOS 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
), any numpad digit key using KP_
prefix (i.e. from KP_0
to KP_9
) or one of the special strings listed below (again, case doesn’t matter) corresponding to the specified key code:

label (string) –
Note
In wxGTK using "SHIFT"
with non-alphabetic characters currently doesn’t work, even in combination with other modifiers, due to GTK+ limitation. E.g. Shift+Ctrl+A
works but Shift+Ctrl+1
or Shift+/
do not, so avoid using accelerators of this form in portable code.
Note
In GTk, the left/right/up/down arrow keys do not work as accelerator keys for a menu item unless a modifier key is used. Additionally, the following keycodes are not supported as menu accelerator keys:
WXK_COMMAND/WXK_CONTROL
wx.WXK_SHIFT
wx.WXK_ALT
wx.WXK_SCROLL
wx.WXK_CAPITAL
wx.WXK_NUMLOCK
wx.WXK_NUMPAD_TAB
