Struct gtk4::PopoverMenuBar

#[repr(transparent)]
pub struct PopoverMenuBar { /* private fields */ }

PopoverMenuBar presents a horizontal bar of items that pop up popover menus when clicked.

The only way to create instances of PopoverMenuBar is from a GMenuModel.

CSS nodes

menubar
├── item[.active]
┊   ╰── popover
╰── item
    ╰── popover

PopoverMenuBar has a single CSS node with name menubar, below which each item has its CSS node, and below that the corresponding popover.

The item whose popover is currently open gets the .active style class.

Accessibility

PopoverMenuBar uses the AccessibleRole::MenuBar role, the menu items use the AccessibleRole::MenuItem role and the menus use the AccessibleRole::Menu role.

Implementations

impl PopoverMenuBar

pub fn from_model(model: Option<&impl IsA<MenuModel>>) -> PopoverMenuBar

Creates a PopoverMenuBar from a GMenuModel.

model

a GMenuModel

Returns

a new PopoverMenuBar

pub fn builder() -> PopoverMenuBarBuilder

Creates a new builder-pattern struct instance to construct PopoverMenuBar objects.

This method returns an instance of PopoverMenuBarBuilder which can be used to create PopoverMenuBar objects.

pub fn add_child(&self, child: &impl IsA<Widget>, id: &str) -> bool

Adds a custom widget to a generated menubar.

For this to work, the menu model of @self must have an item with a custom attribute that matches @id.

child

the Widget to add

id

the ID to insert @child at

Returns

true if @id was found and the widget added

pub fn menu_model(&self) -> Option<MenuModel>

Returns the model from which the contents of @self are taken.

Returns

a GMenuModel

pub fn remove_child(&self, child: &impl IsA<Widget>) -> bool

Removes a widget that has previously been added with gtk_popover_menu_bar_add_child().

child

the Widget to remove

Returns

true if the widget was removed

pub fn set_menu_model(&self, model: Option<&impl IsA<MenuModel>>)

Sets a menu model from which @self should take its contents.

model

a GMenuModel

pub fn connect_menu_model_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

impl<OT: ObjectType> PartialEq<OT> for PopoverMenuBar

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
