.
- Returns:
true
if the widget was activatable.
Reimplemented from Gtk::Widget.

void Gtk::MenuItem::remove_submenu | ( | ) |
Removes the widget's submenu.
Deprecated: 2.12: remove_submenu() is deprecated and should not be used in newly written code. Use set_submenu() instead.
void Gtk::MenuItem::select | ( | ) |
Reimplemented from Gtk::Item.
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_accel_map_save() on this).
To setup 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 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_path Accelerator path, corresponding to this menu item's functionality.
void Gtk::MenuItem::set_label | ( | const Glib::ustring & | label | ) |
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_justified If 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:
-
submenu The 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.
- Parameters:
-
setting true
if underlines in the text indicate mnemonics.
