Struct ContainerFlag

pub struct ContainerFlag(/* private fields */);

The same as FocusFlag, but distinct to mark the focus for a container.

This serves the purpose of

• summarizing the focus for the container. If any of the widgets of the container has the focus, the container itself has the focus.
• identifying the container for some functions on Focus.

Implementations

impl ContainerFlag

pub fn new() -> Self

Create a default flag.

pub fn named(name: &str) -> Self

Create a named flag.

pub fn get(&self) -> bool

Has the focus.

pub fn set(&self, focus: bool)

Set the focus.

pub fn name(&self) -> &str

Get the field-name.

pub fn lost(&self) -> bool

Just lost the focus.

pub fn set_lost(&self, lost: bool)

pub fn gained(&self) -> bool

Just gained the focus.

pub fn set_gained(&self, gained: bool)

pub fn clear(&self)

Reset all flags to false.

Trait Implementations

impl Clone for ContainerFlag

fn clone(&self) -> ContainerFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContainerFlag

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

Formats the value using the given formatter.

impl Default for ContainerFlag

fn default() -> ContainerFlag

Returns the “default value” for a type.

impl Display for ContainerFlag

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

Formats the value using the given formatter.

impl FocusContainer for ContainerFlag

fn build(&self, _builder: &mut FocusBuilder)

Build the focus-structure for the container.

fn container(&self) -> Option<ContainerFlag>

Returns the container-flag.

fn area(&self) -> Rect

Area of the container for mouse-events.

fn area_z(&self) -> u16

Z value for the area.

fn is_container_focused(&self) -> bool

Focused?

fn container_lost_focus(&self) -> bool

Just lost focus.

Just gained focus.

impl Hash for ContainerFlag

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

Feeds this value into the given Hasher.

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 PartialEq for ContainerFlag

Equality for ContainerFlag means pointer equality of the underlying Rc using Rc::ptr_eq.

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

Tests for self and other values to be equal, and is used by ==.

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

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