Expand description

Trait containing all MenuItem methods.

§Implementors

CheckMenuItem, MenuItem, SeparatorMenuItem

Provided Methods§

Source

fn deselect(&self)

Emits the deselect signal on the given item.

Source

fn accel_path(&self) -> Option<GString>

Retrieve the accelerator path that was previously set on self.

See set_accel_path() for details.

§Returns

the accelerator path corresponding to this menu item’s functionality, or None if not set

Source

fn label(&self) -> Option<GString>

Sets text on the self label

§Returns

The text in the self label. This is the internal string used by the label, and must not be modified.

Source

fn must_reserve_indicator(&self) -> bool

Returns whether the self reserves space for the submenu indicator, regardless if it has a submenu or not.

§Returns

true if self always reserves space for the submenu indicator

Source

fn submenu(&self) -> Option<Widget>

Gets the submenu underneath this menu item, if any. See set_submenu().

§Returns

submenu for this menu item, or None if none

Source

fn uses_underline(&self) -> bool

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

§Returns

true if an embedded underline in the label indicates the mnemonic accelerator key.

Source

fn select(&self)

Emits the select signal on the given item.

Source

fn set_accel_path(&self, accel_path: Option<&str>)

Set the accelerator path on self, 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 GtkMenuExt::set_accel_path() for a more convenient variant of this function.

This function is basically a convenience wrapper that handles calling WidgetExt::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 GtkMenuExt::set_accel_group() for this to work.

Note that accel_path string will be stored in a GQuark. Therefore, if you pass a static string, you can save some memory by interning it first with g_intern_static_string().
