Trait i_slint_backend_winit::WinitWindowAccessor

pub trait WinitWindowAccessor: WinitWindowAccessorSealed {
    // Required methods
    fn has_winit_window(&self) -> bool;
    fn with_winit_window<T>(
        &self,
        callback: impl FnOnce(&Window) -> T,
    ) -> Option<T>;
    fn on_winit_window_event(
        &self,
        callback: impl FnMut(&Window, &WindowEvent) -> WinitWindowEventResult + 'static,
    );
}

This helper trait can be used to obtain access to the winit::window::Window for a given slint::Window.

Required Methods

fn has_winit_window(&self) -> bool

Returns true if a winit::window::Window exists for this window. This is the case if the window is backed by this winit backend.

fn with_winit_window<T>(&self, callback: impl FnOnce(&Window) -> T) -> Option<T>

Invokes the specified callback with a reference to the winit::window::Window that exists for this Slint window and returns Some(T); otherwise None.

fn on_winit_window_event( &self, callback: impl FnMut(&Window, &WindowEvent) -> WinitWindowEventResult + 'static, )

Registers a window event filter callback for this Slint window.

The callback is invoked in the winit event loop whenever a window event is received with a reference to the slint::Window and the winit::event::WindowEvent. The return value of the callback specifies whether Slint should handle this event.

If this window is not backed by winit, this function is a no-op.

Object Safety

This trait is not object safe.
