Struct RawContext 

Source 
pub struct RawContext(/* private fields */);
Expand description

Safe thin wrapper for ImGuiContext.

This has common read-only functions.

Implementations§

Source§

impl RawContext

Source

pub fn get(&self) -> &ImGuiContext

Gets a reference to the native wrapper struct.

Source§

impl RawContext

Source

pub fn cast(r: &ImGuiContext) -> &RawContext

Converts a native reference into a wrapper reference.

Source

pub fn cast_mut(r: &mut ImGuiContext) -> &mut RawContext

Converts a native reference into a wrapper reference.

It is safe because if you have a reference to the native reference, you already can change anything.

Source§

impl RawContext

Source

pub unsafe fn current<'a>() -> &'a RawContext

Gets the current ImGui context.

SAFETY: unsafe because the reference lifetime is not well defined.

Source

pub unsafe fn from_ptr<'a>(ptr: *mut ImGuiContext) -> &'a RawContext

Converts a raw DearImGui context pointer into a `&RawContext``.

Source

pub unsafe fn from_ptr_mut<'a>(ptr: *mut ImGuiContext) -> &'a mut RawContext

Converts a raw DearImGui context pointer into a `&mut RawContext``.

Source

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

Gets a reference to the actual DearImGui context struct.

Source

pub fn platform_io(&self) -> &PlatformIo

Returns a safe wrapper for the PlatformIo.

Source

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

Returns an unsafe mutable wrapper for the PlatformIo.

Source

pub fn io(&self) -> &Io

Returns a safe wrapper for the IO.

Source

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

Source

pub fn style(&self) -> &Style

Returns a reference for the current style definition.

Source

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

Gets a mutable reference to the style definition.

Source

pub fn get_main_viewport(&self) -> &Viewport

Gets a reference to the main viewport
