Trait ModifyWindow

pub trait ModifyWindow {
    // Required methods
    fn modify_window<T>(&mut self, f: impl FnOnce(&Window) -> T) -> Option<T>;
    fn window(&self) -> Option<Arc<Window>>;
}

Required Methods

fn modify_window<T>(&mut self, f: impl FnOnce(&Window) -> T) -> Option<T>

Takes a closure which mutates the parent window of the current view.

fn window(&self) -> Option<Arc<Window>>

Returns a read-only pointer to the parent window of the current view.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
