Struct OptionMenu 

pub struct OptionMenu { /* private fields */ }

Represents the dropdown menu of a select element in a WebView.

When a select element in a WebView needs to display a dropdown menu, the signal show-option-menu is emitted, providing a WebKitOptionMenu with the OptionMenuItems that should be displayed.

Signals

close

Emitted when closing a OptionMenu is requested. This can happen when the user explicitly calls OptionMenu::close() or when the element is detached from the current page.

GLib type: GObject with reference counted clone semantics.

Implementations

impl OptionMenu

pub fn activate_item(&self, index: u32)

Activates the OptionMenuItem at index in self.

Activating an item changes the value of the element making the item the active one. You are expected to close the menu with close() after activating an item, calling this function again will have no effect.

index

the index of the item

pub fn close(&self)

Request to close a OptionMenu.

This emits WebKitOptionMenu::close signal. This function should always be called to notify WebKit that the associated menu has been closed. If the menu is closed and neither select_item() nor activate_item() have been called, the element value remains unchanged.

pub fn event(&self) -> Option<Event>

Gets the gdk::Event that triggered the dropdown menu. If self was not triggered by a user interaction, like a mouse click, None is returned.

Returns

the menu event or None.

pub fn item(&self, index: u32) -> Option<OptionMenuItem>

Returns the OptionMenuItem at index in self.

index

the index of the item

Returns

a OptionMenuItem of self.

pub fn n_items(&self) -> u32

Gets the length of the self.

Returns

the number of OptionMenuItems in self

pub fn select_item(&self, index: u32)

Selects the OptionMenuItem at index in self.

Selecting an item changes the text shown by the combo button, but it doesn’t change the value of the element. You need to explicitly activate the item with select_item() or close the menu with close() in which case the currently selected item will be activated.

index

the index of the item

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

Emitted when closing a OptionMenu is requested. This can happen when the user explicitly calls close() or when the element is detached from the current page.

Trait Implementations

impl Clone for OptionMenu

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OptionMenu

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for OptionMenu

type ParamSpec = ParamSpecObject

type SetValue = OptionMenu

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, OptionMenu>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for OptionMenu

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for OptionMenu

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for OptionMenu

type Parent = Object

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

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

impl<OT: ObjectType> PartialOrd<OT> for OptionMenu

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for OptionMenu

fn static_type() -> Type

Returns the type identifier of Self.
