Struct Region 

pub struct Region<ID> { /* private fields */ }

A region representing a rectangular area with an associated widget ID.

This struct is used to define the position and size of widgets within the GUI.

Implementations

impl<ID: WidgetId> Region<ID>

pub const fn new(id: ID, x: i16, y: i16, w: u16, h: u16) -> Self

Creates a new region with the specified ID and dimensions.

Arguments

• id - The widget ID for this region
• x - The x-coordinate of the top-left corner
• y - The y-coordinate of the top-left corner
• w - The width of the region
• h - The height of the region

pub const fn new_with_area(id: ID, area: LwRectangle<i16, u16>) -> Self

Creates a new region with the specified ID and area.

pub const fn zero(id: ID) -> Self

Creates a new region with zero dimensions at the origin.

Arguments

• id - The widget ID for this region

pub const fn id(&self) -> ID

Returns the widget ID associated with this region.

pub const fn replace_id(&self, id: ID) -> Self

Replace the widget ID of the region.

pub fn top_left(&self) -> Point

Returns the top-left corner of the region as a Point.

pub fn size(&self) -> Size

Returns the size of the region as a Size.

pub fn rectangle(&self) -> Rectangle

Returns the region as a Rectangle.

pub const fn x(&self) -> i32

Returns the x-coordinate of the top-left corner as an i32.

pub const fn y(&self) -> i32

Returns the y-coordinate of the top-left corner as an i32.

pub const fn width(&self) -> u32

Returns the width of the region as a u32.

pub const fn height(&self) -> u32

Returns the height of the region as a u32.

pub fn delta_resize(&self, delta: DeltaResize) -> Region<ID>

Returns a new region resized according to the specified delta.

Arguments

• delta - The resize delta to use for resizing

pub fn move_by(&self, dx: i16, dy: i16) -> Self

Moves the region by the specified amount.

Arguments

• dx - The x-direction offset
• dy - The y-direction offset

Returns

A new Region instance with the moved position.

pub fn resized( &self, width: u16, height: u16, anchor_point: AnchorPoint, ) -> Self

Returns a new region resized according to the specified width and height.

Arguments

• width - The new width of the region
• height - The new height of the region
• anchor_point - The anchor point to use for resizing

Returns

A new Region instance with the resized dimensions.

Trait Implementations

impl<ID: Clone> Clone for Region<ID>

fn clone(&self) -> Region<ID>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<ID: Debug> Debug for Region<ID>

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

Formats the value using the given formatter.

impl<ID: Default> Default for Region<ID>

fn default() -> Region<ID>

Returns the “default value” for a type.

impl<ID: PartialEq> PartialEq for Region<ID>

fn eq(&self, other: &Region<ID>) -> 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.
