Struct gdnative::api::CheckBox

pub struct CheckBox { /* fields omitted */ }

core class CheckBox inherits Button (unsafe).

Official documentation

See the documentation of this class in the Godot engine's official documentation.

Memory management

Non reference counted objects such as the ones of this type are usually owned by the engine.

CheckBox is a reference-only type. Persistent references can only exist in the unsafe Ref<CheckBox> form.

In the cases where Rust code owns an object of this type, for example if the object was just created on the Rust side and not passed to the engine yet, ownership should be either given to the engine or the object must be manually destroyed using Ref::free, or Ref::queue_free if it is a Node.

Class hierarchy

CheckBox inherits methods from:

• Button
• BaseButton
• Control
• CanvasItem
• Node
• Object

Safety

All types in the Godot API have "interior mutability" in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl CheckBox

pub fn new() -> Ref<CheckBox, Unique>

Creates a new instance of this object.

Because this type is not reference counted, the lifetime of the returned object is not automatically managed.

Immediately after creation, the object is owned by the caller, and can be passed to the engine (in which case the engine will be responsible for destroying the object) or destroyed manually using Ref::free, or preferably Ref::queue_free if it is a Node.

Methods from Deref<Target = Button>

pub const ALIGN_CENTER: i64

pub const ALIGN_LEFT: i64

pub const ALIGN_RIGHT: i64

pub fn button_icon(&self) -> Option<Ref<Texture, Shared>>

Button's icon, if text is present the icon will be placed before the text.

pub fn clip_text(&self) -> bool

When this property is enabled, text that is too large to fit the button is clipped, when disabled the Button will always be wide enough to hold the text.

pub fn text(&self) -> GodotString

The button's text that will be displayed inside the button's area.

pub fn text_align(&self) -> TextAlign

Text alignment policy for the button's text, use one of the [enum TextAlign] constants.

pub fn is_expand_icon(&self) -> bool

When enabled, the button's icon will expand/shrink to fit the button's size while keeping its aspect.

pub fn is_flat(&self) -> bool

Flat buttons don't display decoration.

pub fn set_button_icon(&self, texture: impl AsArg<Texture>)

Button's icon, if text is present the icon will be placed before the text.

pub fn set_clip_text(&self, enabled: bool)

When this property is enabled, text that is too large to fit the button is clipped, when disabled the Button will always be wide enough to hold the text.

pub fn set_expand_icon(&self, arg0: bool)

When enabled, the button's icon will expand/shrink to fit the button's size while keeping its aspect.

pub fn set_flat(&self, enabled: bool)

Flat buttons don't display decoration.

pub fn set_text(&self, text: impl Into<GodotString>)

The button's text that will be displayed inside the button's area.

pub fn set_text_align(&self, align: i64)

Text alignment policy for the button's text, use one of the [enum TextAlign] constants.

Trait Implementations

impl Debug for CheckBox

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

Formats the value using the given formatter.

impl Deref for CheckBox

type Target = Button

The resulting type after dereferencing.

fn deref(&self) -> &Button

Dereferences the value.

impl DerefMut for CheckBox

fn deref_mut(&mut self) -> &mut Button

Mutably dereferences the value.

impl GodotObject for CheckBox

type RefKind = ManuallyManaged

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information.

fn class_name() -> &'static str

fn null() -> Null<Self>

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option.

fn new() -> Ref<Self, Unique> where
    Self: Instanciable, 

Creates a new instance of Self using a zero-argument constructor, as a Unique reference.

fn cast<T>(&self) -> Option<&T> where
    T: GodotObject + SubClass<Self>, 

Performs a dynamic reference downcast to target type.

fn upcast<T>(&self) -> &T where
    Self: SubClass<T>,
    T: GodotObject, 

Performs a static reference upcast to a supertype that is guaranteed to be valid.

unsafe fn assume_shared(&self) -> Ref<Self, Shared>

Creates a persistent reference to the same Godot object with shared thread access.

unsafe fn assume_thread_local(&self) -> Ref<Self, ThreadLocal> where
    Self: GodotObject<RefKind = RefCounted>, 

Creates a persistent reference to the same Godot object with thread-local thread access.

unsafe fn assume_unique(&self) -> Ref<Self, Unique>

Creates a persistent reference to the same Godot object with unique access.
