MenuItem

The #GtkMenuItem widget and the derived widgets are the only valid children for menus. Their function is to correctly handle highlighting, alignment, events and submenus.

As a GtkMenuItem derives from #GtkBin it can hold any valid child widget, although only a few are really useful.

By default, a GtkMenuItem sets a #GtkAccelLabel as its child. GtkMenuItem has direct functions to set the label and its mnemonic. For more advanced label settings, you can fetch the child widget from the GtkBin.

An example for setting markup and accelerator on a MenuItem: |[ GtkWidget *child = gtk_bin_get_child (GTK_BIN (menu_item)); gtk_label_set_markup (GTK_LABEL (child), "<i>new label</i> with <b>markup</b>"); gtk_accel_label_set_accel (GTK_ACCEL_LABEL (child), GDK_KEY_1, 0); ]|

GtkMenuItem as GtkBuildable

The GtkMenuItem implementation of the #GtkBuildable interface supports adding a submenu by specifying “submenu” as the “type” attribute of a <child> element.

An example of UI definition fragment with submenus: |[ <object class="GtkMenuItem"> <child type="submenu"> <object class="GtkMenu"/> </child> </object> ]|

CSS nodes

|[ menuitem ├── <child> ╰── arrow.right ]|

GtkMenuItem has a single CSS node with name menuitem. If the menuitem has a submenu, it gets another CSS node with name arrow, which has the .left or .right style class.

Constructors

this this(GtkMenuItem* gtkMenuItem, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(string label, void delegate(MenuItem) dlg, string action): Creates a new menu item with a label and a listener and a action. used for backward compatibily with DUI.
this this(void delegate(MenuItem) dlg, string label, string action, bool mnemonic, AccelGroup accelGroup, char accelKey, GdkModifierType modifierType, GtkAccelFlags accelFlags): Creates a new Item associated with a "activate" delegate and with a action code and optionally accelGroup
this this(void delegate(MenuItem) dlg, string label, bool mnemonic): Creates a new Item associated with a "activate" delegate
this this(string label, bool mnemonic): Creates a new GtkMenuItem whose child is a GtkLabel.
this this(): Creates a new #GtkMenuItem.

Members

Functions

addOnActivate void addOnActivate(void delegate(MenuItem) dlg, ConnectFlags connectFlags): Emitted when the item is activated.
addOnActivateItem void addOnActivateItem(void delegate(MenuItem) dlg, ConnectFlags connectFlags): Emitted when the item is activated, but also if the menu item has a submenu. For normal applications, the relevant signal is #GtkMenuItem::activate.
addOnDeselect void addOnDeselect(void delegate(MenuItem) dlg, ConnectFlags connectFlags)
addOnSelect void addOnSelect(void delegate(MenuItem) dlg, ConnectFlags connectFlags)
addOnToggleSizeAllocate void addOnToggleSizeAllocate(void delegate(int, MenuItem) dlg, ConnectFlags connectFlags)
addOnToggleSizeRequest void addOnToggleSizeRequest(void delegate(void*, MenuItem) dlg, ConnectFlags connectFlags)
deselect void deselect(): Emits the #GtkMenuItem::deselect signal on the given item.
getAccelPath string getAccelPath(): Retrieve the accelerator path that was previously set on @menu_item.
getActionName string getActionName(): Gets the application set action code
getLabel string getLabel(): Sets @text on the @menu_item label
getMenuItemStruct GtkMenuItem* getMenuItemStruct(): Get the main Gtk struct
getReserveIndicator bool getReserveIndicator(): Returns whether the @menu_item reserves space for the submenu indicator, regardless if it has a submenu or not.
getRightJustified bool getRightJustified(): Gets whether the menu item appears justified at the right side of the menu bar.
getStruct void* getStruct(): the main Gtk struct as a void*
getSubmenu Widget getSubmenu(): Gets the submenu underneath this menu item, if any. See gtk_menu_item_set_submenu().
getUseUnderline bool getUseUnderline(): Checks if an underline in the text indicates the next character should be used for the mnemonic accelerator key.
itemActivate void itemActivate(): Emits the #GtkMenuItem::activate signal on the given item
select void select(): Emits the #GtkMenuItem::select signal on the given item.
setAccelPath void setAccelPath(string accelPath): Set the accelerator path on @menu_item, through which runtime changes of the menu item’s accelerator caused by the user can be identified and saved to persistent storage (see gtk_accel_map_save() on this). To set up a default accelerator for this menu item, call gtk_accel_map_add_entry() with the same @accel_path. See also gtk_accel_map_add_entry() on the specifics of accelerator paths, and gtk_menu_set_accel_path() for a more convenient variant of this function.
setLabel void setLabel(string label): Sets @text on the @menu_item label
setReserveIndicator void setReserveIndicator(bool reserve): Sets whether the @menu_item should reserve space for the submenu indicator, regardless if it actually has a submenu or not.
setRightJustified void setRightJustified(bool rightJustified): Sets whether the menu item appears justified at the right side of a menu bar. This was traditionally done for “Help” menu items, but is now considered a bad idea. (If the widget layout is reversed for a right-to-left language like Hebrew or Arabic, right-justified-menu-items appear at the left.)
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
setSubmenu void setSubmenu(Menu submenu): Sets or replaces the menu item’s submenu, or removes it when a %NULL submenu is passed.
setUseUnderline void setUseUnderline(bool setting): If true, an underline in the text indicates the next character should be used for the mnemonic accelerator key.
toggleSizeAllocate void toggleSizeAllocate(int allocation): Emits the #GtkMenuItem::toggle-size-allocate signal on the given item.
toggleSizeRequest void toggleSizeRequest(int requisition): Emits the #GtkMenuItem::toggle-size-request signal on the given item.
