Gtk::MenuItemwrap (GtkMenuItem* object, bool take_copy=false)
 A Glib::wrap() method for this object.

Detailed Description

Child item for menus.

Handle highlighting, alignment, events and submenus. As it derives from Gtk::Bin it can hold any valid child widget, altough only a few are really useful.


Constructor & Destructor Documentation

virtual Gtk::MenuItem::~MenuItem (  ) [virtual]
Gtk::MenuItem::MenuItem (  )

Create an empty menu item.

Gtk::MenuItem::MenuItem ( Widget widget ) [explicit]

Create a menu item with widget.

Gtk::MenuItem::MenuItem ( const Glib::ustring label,
bool  mnemonic = false 
) [explicit]

Create a menu item with label.


Member Function Documentation

void Gtk::MenuItem::accelerate ( Window window )
void Gtk::MenuItem::activate (  )

For widgets that can be "activated" (buttons, menu items, etc.) this function activates them.

Activation is what happens when you press Enter on a widget during key navigation. If widget isn't activatable, the function returns false.

Returns:
true if the widget was activatable.

Reimplemented from Gtk::Widget.

Retrieve the accelerator path that was previously set on menu_item.

See set_accel_path() for details.

Since gtkmm 2.14:
Returns:
The accelerator path corresponding to this menu item's functionality, or 0 if not set.
Glib::ustring Gtk::MenuItem::get_label (  ) const

Sets text on the menu_item label.

Since gtkmm 2.16:
Returns:
The text in the menu_item label. This is the internal string used by the label, and must not be modified.
bool Gtk::MenuItem::get_reserve_indicator (  ) const
bool Gtk::MenuItem::get_right_justified (  ) const

Gets whether the menu item appears justified at the right side of the menu bar.

Returns:
true if the menu item will appear at the far right if added to a menu bar.

See set_submenu().

Returns:
Submenu for this menu item, or 0 if none.
bool Gtk::MenuItem::get_use_underline (  ) const

Checks if an underline in the text indicates the next character should be used for the mnemonic accelerator key.

Since gtkmm 2.16:
Returns:
true if an embedded underline in the label indicates the mnemonic accelerator key.

Glib::PropertyProxy<Glib::ustring> Gtk::MenuItem::property_accel_path (  )

Sets the accelerator path of the menu item.

void Gtk::MenuItem::select (  )
void Gtk::MenuItem::set_accel_key ( const AccelKey accel_key ) [protected]
void Gtk::MenuItem::set_accel_path ( const Glib::ustring accel_path )

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 persistant storage (see Gtk::AccelMap::save() on this).

To setup a default accelerator for this menu item, call Gtk::AccelMap::add_entry() with the same accel_path. See also Gtk::AccelMap::add_entry() on the specifics of accelerator paths, and set_accel_path() for a more convenient variant of this function.

This function is basically a convenience wrapper that handles calling Gtk::Widget::set_accel_path() with the appropriate accelerator group for the menu item.

Note that you do need to set an accelerator on the parent menu with set_accel_group() for this to work.

Parameters:
accel_pathAccelerator path, corresponding to this menu item's functionality.
void Gtk::MenuItem::set_label ( const Glib::ustring label )

Sets text on the menu_item label.

Since gtkmm 2.16:
Parameters:
labelThe text you want to set.
void Gtk::MenuItem::set_reserve_indicator ( bool  reserve = true )
void Gtk::MenuItem::set_right_justified ( bool  right_justified = true )

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.)

Parameters:
right_justifiedIf true the menu item will appear at the far right if added to a menu bar.
void Gtk::MenuItem::set_submenu ( Menu submenu )

Sets or replaces the menu item's submenu, or removes it when a 0 submenu is passed.

Parameters:
submenuThe submenu, or 0.
void Gtk::MenuItem::set_use_underline ( bool  setting = true )

If true, an underline in the text indicates the next character should be used for the mnemonic accelerator key.

Since gtkmm 2.16:
Parameters:
settingtrue if underlines in the text indicate mnemonics.
