wx.MenuItem¶
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+.
Events Emitted by this Class¶
Handlers bound for the following event types will receive one of the wx.CommandEvent wx.MenuEvent parameters.
EVT_MENU: Process a
wxEVT_MENUcommand, which is generated by a menu item. This type of event is sent as wx.CommandEvent.EVT_MENU_RANGE: Process a
wxEVT_MENUcommand, 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.

Class API¶
- class wx.MenuItem(Object)¶
Possible constructors:
MenuItem(parentMenu=None, id=ID_SEPARATOR, text='', helpString='', kind=ITEM_NORMAL, subMenu=None) -> None
A menu item represents an item in a menu.
Methods¶
- __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
IDand leave text and helpString empty. Some platforms (currently wxGTK only, and see the remark inSetBitmapdocumentation) 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 (wx.Menu) – Menu that the menu item belongs to. Can be
Noneif 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 beITEM_SEPARATORinstead.text (string) – Text for the menu item, as shown on the menu. See
SetItemLabelfor more info.helpString (string) – Optional help string that will be shown on the status bar.
kind (ItemKind) – May be
ITEM_SEPARATOR,ITEM_NORMAL,ITEM_CHECKorITEM_RADIO.subMenu (wx.Menu) – If not
None, indicates that the menu item is a submenu.
- Return type:
None
- 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.

None
- ClearExtraAccels(self)¶
Clear the extra accelerators list.
This doesn’t affect the main item accelerator (if any).

- SetBitmap(self, *args, **kw)¶
-
SetBitmap (self, bmp)
Sets the bitmap for the menu item.
Notice that GTK+ uses a global setting called
gtk-menu-imagesto 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 (wx.BitmapBundle)
- Return type:
None
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
Trueor 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.
- Parameters:
bmp (wx.BitmapBundle)
checked (bool)
- Return type:
None
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.
- Parameters:
checked (wx.BitmapBundle)
unchecked (wx.BitmapBundle)
- Return type:
None
Availability
Only available for MSW.
- SetDisabledBitmap(self, disabled)¶

Only available for MSW.
- SetFont(self, font)¶
Sets the font associated with the menu item.
- Parameters:
font (wx.Font)
- Return type:
None
Availability
Only available for MSW.
- SetHelp(self, helpString)¶
Sets the help string.
- Parameters:
helpString (string)
- Return type:
None
- SetItemLabel(self, label)¶
Sets the label associated with the menu item.
Note that if the
IDof this menu item corresponds to a stockID, then it is not necessary to specify a label: wxWidgets will automatically use the stock item label associated with thatID. See theconstructorfor 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
\tfollowed 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 thatCTRLcorresponds 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 useRAWCTRLto prevent this mapping. Under the other platformsRAWCTRLis the same as plainCTRL.The accelerator may be any alphanumeric character, any function key (from
F1toF12), any numpad digit key usingKP_prefix (i.e. fromKP_0toKP_9) or one of the special strings listed below (again, case doesn’t matter) corresponding to the specified key code:DelorDelete:wx.WXK_DELETEBack:wx.WXK_BACKInsorInsert:wx.WXK_INSERTEnterorReturn:wx.WXK_RETURNPgUporPageUp:wx.WXK_PAGEUPPgDnorPageDown:wx.WXK_PAGEDOWNLeft:wx.WXK_LEFTRight:wx.WXK_RIGHTUp:wx.WXK_UPDown:wx.WXK_DOWNHome:wx.WXK_HOMEEnd:wx.WXK_ENDSpace:wx.WXK_SPACETab:wx.WXK_TABEscorEscape:wx.WXK_ESCAPECancel:wx.WXK_CANCELClear:wx.WXK_CLEARMenu:wx.WXK_MENUPause:wx.WXK_PAUSECapital:wx.WXK_CAPITALSelect:wx.WXK_SELECTPrint:wx.WXK_PRINTExecute:wx.WXK_EXECUTESnapshot:wx.WXK_SNAPSHOTHelp:wx.WXK_HELPAdd:wx.WXK_ADDSeparator:wx.WXK_SEPARATORSubtract:wx.WXK_SUBTRACTDecimal:wx.WXK_DECIMALDivide:wx.WXK_DIVIDENum_lock:wx.WXK_NUMLOCKScroll_lock:wx.WXK_SCROLLKP_Space:wx.WXK_NUMPAD_SPACEKP_Tab:wx.WXK_NUMPAD_TABKP_Enter:wx.WXK_NUMPAD_ENTERKP_Home:wx.WXK_NUMPAD_HOMEKP_Left:wx.WXK_NUMPAD_LEFTKP_Up:wx.WXK_NUMPAD_UPKP_Right:wx.WXK_NUMPAD_RIGHTKP_Down:wx.WXK_NUMPAD_DOWNKP_PageUp:wx.WXK_NUMPAD_PAGEUPKP_PageDown:wx.WXK_NUMPAD_PAGEDOWNKP_Prior:wx.WXK_NUMPAD_PAGEUPKP_Next:wx.WXK_NUMPAD_PAGEDOWNKP_End:wx.WXK_NUMPAD_ENDKP_Begin:wx.WXK_NUMPAD_BEGINKP_Insert:wx.WXK_NUMPAD_INSERTKP_Delete:wx.WXK_NUMPAD_DELETEKP_Equal:wx.WXK_NUMPAD_EQUALKP_Multiply:wx.WXK_NUMPAD_MULTIPLYKP_Add:wx.WXK_NUMPAD_ADDKP_Separator:wx.WXK_NUMPAD_SEPARATORKP_Subtract:wx.WXK_NUMPAD_SUBTRACTKP_Decimal:wx.WXK_NUMPAD_DECIMALKP_Divide:wx.WXK_NUMPAD_DIVIDEWindows_Left:wx.WXK_WINDOWS_LEFTWindows_Right:wx.WXK_WINDOWS_RIGHTWindows_Menu:wx.WXK_WINDOWS_MENUCommand:wx.WXK_COMMAND

- Parameters:
label (string)
- Return type:
None
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+Aworks butShift+Ctrl+1orShift+/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_SHIFTwx.WXK_ALTwx.WXK_SCROLLwx.WXK_CAPITALwx.WXK_NUMLOCKwx.WXK_NUMPAD_TABwx.WXK_TABwx.WXK_WINDOWS_LEFTwx.WXK_WINDOWS_RIGHTwx.WXK_ADDwx.WXK_SEPARATORwx.WXK_SUBTRACTwx.WXK_DECIMALwx.WXK_DIVIDEwx.WXK_SNAPSHOT
