Struct UiState 

struct UiState<B: Backend> {
    backend: Rc<B>,
    layout: Layout<B::Widget>,
    windows: Vec<Option<WindowState<B>>>,
    on_close: Option<WindowCloseHandler>,
}

Fields

backend: Rc<B>

layout: Layout<B::Widget>

windows: Vec<Option<WindowState<B>>>

Indexed by WindowId; None once closed, so the ids of other windows stay valid.

on_close: Option<WindowCloseHandler>

What runs when the user asks to close a window; without one, it closes.

Implementations

impl<B: Backend> UiState<B>

fn window(&self, window: WindowId) -> &WindowState<B>

fn invalidate(&mut self, window: WindowId)

fn resize(&mut self, window: WindowId, size: Size)

A closed window can still report a resize that was already on its way, so that is ignored rather than treated as a mistake.

fn remove_tree(&mut self, node: NodeId)

Removes node and everything under it, taking their widgets off screen.

fn layout_window(&mut self, window: WindowId)
