Struct sixtyfps_corelib::eventloop::ComponentWindow

#[repr(C)]pub struct ComponentWindow(pub Rc<dyn GenericWindow>);

The ComponentWindow is the (rust) facing public type that can render the items of components to the screen.

Implementations

impl ComponentWindow

pub fn new(window_impl: Rc<dyn GenericWindow>) -> Self

Creates a new instance of a CompomentWindow based on the given window implementation. Only used internally.

pub fn run(
    &self,
    component: Pin<VRef<'_, ComponentVTable>>,
    root_item: Pin<ItemRef<'_>>
)

Spins an event loop and renders the items of the provided component in this window.

pub fn scale_factor(&self) -> f32

Returns the scale factor set on the window.

pub fn set_scale_factor(&self, factor: f32)

Sets an overriding scale factor for the window. This is typically only used for testing.

pub fn free_graphics_resources(&self, component: Pin<ComponentRef<'_>>)

This function is called by the generated code when a component and therefore its tree of items are destroyed. The implementation typically uses this to free the underlying graphics resources cached via RenderingCache.

pub fn set_focus_item(
    &self,
    component: Pin<ComponentRef<'_>>,
    item: Pin<VRef<'_, ItemVTable>>
)

Clears the focus on any previously focused item and makes the provided item the focus item, in order to receive future key events.

Trait Implementations

impl Clone for ComponentWindow

fn clone(&self) -> ComponentWindow

Returns a copy of the value.

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

Performs copy-assignment from source.
