Required Methods
sourcefn accel_path(&self) -> Option<GString>
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
sourcefn label(&self) -> Option<GString>
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.
sourcefn must_reserve_indicator(&self) -> bool
fn must_reserve_indicator(&self) -> bool
Gets the submenu underneath this menu item, if any.
See set_submenu()
.
Returns
submenu for this menu item, or None
if none
sourcefn uses_underline(&self) -> bool
fn uses_underline(&self) -> bool
sourcefn set_accel_path(&self, accel_path: Option<&str>)
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()
.
accel_path
accelerator path, corresponding to this menu
item’s functionality, or None
to unset the current path.
sourcefn set_reserve_indicator(&self, reserve: bool)
fn set_reserve_indicator(&self, reserve: bool)
Sets whether the self
should reserve space for
the submenu indicator, regardless if it actually has
a submenu or not.
There should be little need for applications to call this functions.
reserve
the new value
sourcefn set_use_underline(&self, setting: bool)
fn set_use_underline(&self, setting: bool)
sourcefn toggle_size_allocate(&self, allocation: i32)
fn toggle_size_allocate(&self, allocation: i32)
Emits the signal::MenuItem::toggle-size-allocate
signal on the given item.
allocation
the allocation to use as signal data.
sourcefn toggle_size_request(&self, requisition: &mut i32)
fn toggle_size_request(&self, requisition: &mut i32)
Emits the signal::MenuItem::toggle-size-request
signal on the given item.
requisition
the requisition to use as signal data.
sourcefn is_right_justified(&self) -> bool
fn is_right_justified(&self) -> bool
Sets whether the menu item appears justified at the right side of a menu bar.
sourcefn set_right_justified(&self, right_justified: bool)
fn set_right_justified(&self, right_justified: bool)
Sets whether the menu item appears justified at the right side of a menu bar.
sourcefn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
Emitted when the item is activated.
fn emit_activate(&self)
sourcefn connect_activate_item<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_activate_item<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
Emitted when the item is activated, but also if the menu item has a
submenu. For normal applications, the relevant signal is
signal::MenuItem::activate
.
