Struct kas::Action

impl Action

pub const REDRAW: Action = _

The whole window requires redrawing

Note that [event::EventCx::redraw] can instead be used for more selective redrawing.

pub const REGION_MOVED: Action = _

Some widgets within a region moved

Used when a pop-up is closed or a region adjusted (e.g. scroll or switch tab) to update which widget is under the mouse cursor / touch events. Identifier is that of the parent widget/window encapsulating the region.

Implies window redraw.

pub const SCROLLED: Action = _

A widget was scrolled

This is used for inter-widget communication (see EditBox). If not handled locally, it is handled identially to Self::SET_RECT.

pub const SET_RECT: Action = _

Reset size of all widgets without recalculating requirements

pub const RESIZE: Action = _

Resize all widgets in the window

pub const RECONFIGURE: Action = _

Reconfigure all widgets of the window

Configuring widgets assigns Id identifiers and calls Events::configure.

pub const UPDATE: Action = _

Update all widgets

This is a notification that input data has changed.

pub const CLOSE: Action = _

The current window should be closed

pub const EXIT: Action = _

Close all windows and exit

impl Action

pub const fn empty() -> Action

Get a flags value with all bits unset.

pub const fn all() -> Action

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u32) -> Option<Action>

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u32) -> Action

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u32) -> Action

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Action>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

pub const fn intersects(&self, other: Action) -> bool

Whether any set bits in a source flags value are also set in a target flags value.

pub const fn contains(&self, other: Action) -> bool

Whether all set bits in a source flags value are also set in a target flags value.

pub fn insert(&mut self, other: Action)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Action)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: Action)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Action, value: bool)

Call insert when value is true or remove when value is false.

pub const fn intersection(self, other: Action) -> Action

The bitwise and (&) of the bits in two flags values.

pub const fn union(self, other: Action) -> Action

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Action) -> Action

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Action) -> Action

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Action

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl Action

pub const fn iter(&self) -> Iter<Action>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<Action>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
