Struct Context

pub struct Context { /* private fields */ }

The main ImGui context.

Implementations

impl Context

pub unsafe fn new() -> Context

Creates a new ImGui context with default values.

SAFETY: It is unsafe because it makes the context current, and that may brake the current context if called at the wrong time.

pub unsafe fn set_size(&mut self, size: Vector2, scale: f32)

Sets the size and scale of the context area.

pub unsafe fn set_current(&mut self) -> CurrentContext<'_>

Makes this context the current one.

SAFETY: Do not make two different contexts current at the same time in the same thread.

pub fn set_ini_file_name(&mut self, ini_file_name: Option<&str>)

Sets the ini file where ImGui persists its data.

By default is None, that means no file is saved.

pub fn ini_file_name(&self) -> Option<&str>

Gets the ini file set previously by set_ini_file_name.

Methods from Deref<Target = RawContext>

pub fn get(&self) -> &ImGuiContext

Gets a reference to the native wrapper struct.

pub unsafe fn inner(&mut self) -> &mut ImGuiContext

Gets a reference to the actual DearImGui context struct.

pub fn platform_io(&self) -> &PlatformIo

Returns a safe wrapper for the PlatformIo.

pub unsafe fn platform_io_mut(&mut self) -> &mut PlatformIo

Returns an unsafe mutable wrapper for the PlatformIo.

pub fn io(&self) -> &Io

Returns a safe wrapper for the IO.

pub fn io_mut(&mut self) -> &mut IoMut

Returns a safe mutable wrapper for the IO.

Use io_mut().inner() to get the unsafe wrapper

pub fn style(&self) -> &Style

Returns a reference for the current style definition.

pub fn style_mut(&mut self) -> &mut Style

Gets a mutable reference to the style definition.

pub fn get_main_viewport(&self) -> &Viewport

Gets a reference to the main viewport

Methods from Deref<Target = ImGuiContext>

pub fn ActiveIdMouseButton(&self) -> i32

Trait Implementations

impl Deref for Context

type Target = RawContext

The resulting type after dereferencing.

fn deref(&self) -> &RawContext

Dereferences the value.

impl DerefMut for Context

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

Mutably dereferences the value.

impl Drop for Context

fn drop(&mut self)

Executes the destructor for this type.
