RootMut

tilo_app::headless

Struct RootMut 

pub struct RootMut<'a, W>
where
    W: Widget + 'static,
{ /* private fields */ }
Expand description

The root of a FrameHarness, to change (FrameHarness::root_mut). Letting go of it takes what the widgets report changed, as the live host does after each event.

Implementations§

§

impl<W> RootMut<'_, W>
where W: Widget + 'static,

pub fn replace(self, root: W)

Put root in the root’s place, as a view that builds its widget anew does: the replacement is reported, as its parent reports it to the live host, and the next frame builds the tree again.
