Struct polyhorn_ios::handles::ViewHandle

pub struct ViewHandle { /* fields omitted */ }

Platform-specific implementation of the view handle trait that can be used to execute imperative code against a view.

Trait Implementations

impl Animatable for ViewHandle

type Animator = Animator

This is the type that can schedule new animations for this object.

type CommandBuffer = CommandBuffer

This is the command buffer that this object can piggy-back on.

fn animate<F>(&mut self, animations: F) where
    F: FnOnce(&mut Animator) + Send + 'static, 

This function should invoke the given callback with a mutable reference to (a new instance of) this object's animator.

fn animate_with_buffer<F>(&mut self, buffer: &mut CommandBuffer, animations: F) where
    F: FnOnce(&mut Animator) + Send + 'static, 

This function should invoke the given callback with a mutable reference to (a new instance of) this object's animator that piggy-backs on the given command buffer. Explicitly passing a command buffer ensures that the animations are started in the same UI event loop iteration as the current render itself.

impl ViewHandle for ViewHandle

fn layout_guide(&self) -> LayoutGuide<f32>

This function should return the layout guides of this view. TODO: on what thread does this occur?

fn size<F>(&self, callback: F) where
    F: FnOnce(Size<f32>) + Send + 'static, 

This function should call the given callback with the size of this view.

fn size_with_buffer<F>(&self, buffer: &mut CommandBuffer, callback: F) where
    F: FnOnce(Size<f32>) + Send + 'static, 

This function should call the given callback with the size of this view. Explicitly passing a command buffer ensures that the dimensions are measured in the same UI event loop iteration as the current render itself.
