Struct rat_focus::FocusFlag

pub struct FocusFlag {
    pub name: Cell<&'static str>,
    pub focus: Cell<bool>,
    pub gained: Cell<bool>,
    pub lost: Cell<bool>,
}

Contains flags for the focus. This struct is embedded in the widget state.

See HasFocusFlag, on_gained! and on_lost!.

Fields

name: Cell<&'static str>

Field name for debugging purposes.

focus: Cell<bool>

Focus.

gained: Cell<bool>

This widget just gained the focus. This flag is set by [Focus::handle] if there is a focus transfer, and will be reset by the next call to [Focus::handle].

See on_gained!

lost: Cell<bool>

This widget just lost the focus. This flag is set by [Focus::handle] if there is a focus transfer, and will be reset by the next call to [Focus::handle].

See on_lost!

Implementations

impl FocusFlag

pub fn get(&self) -> bool

Has the focus.

pub fn set(&self)

Set the focus.

pub fn set_name(&self, name: &'static str)

Set the field-name.

pub fn name(&self) -> &'static str

Get the field-name.

pub fn lost(&self) -> bool

Trait Implementations

impl Clone for FocusFlag

fn clone(&self) -> FocusFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FocusFlag

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

Formats the value using the given formatter.

impl Default for FocusFlag

fn default() -> FocusFlag

Returns the “default value” for a type.

impl PartialEq for FocusFlag

fn eq(&self, other: &FocusFlag) -> 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.
