Struct Drawer 

pub struct Drawer<'a> { /* private fields */ }

A side-anchored slide-in overlay panel.

The open flag drives visibility. While it transitions from false to true the panel slides in from its anchored edge; the reverse plays in reverse. Pressing Esc, clicking the dimmed backdrop, or clicking the built-in close “×” button flips it back to false.

Implementations

impl<'a> Drawer<'a>

pub fn new(id_salt: impl Hash, open: &'a mut bool) -> Self

Create a drawer keyed by id_salt whose visibility is bound to open. Defaults: anchored to the right, 420 pt wide, no title, dismisses on Esc and backdrop click.

pub fn side(self, side: DrawerSide) -> Self

Anchor the drawer to the left or right edge. Default: DrawerSide::Right.

pub fn width(self, width: f32) -> Self

Set the panel width in points. Default: 420. Clamped to at least 120.

pub fn title(self, title: impl Into<WidgetText>) -> Self

Show a strong title at the top of the drawer, alongside the close “×” button. When unset, no automatic chrome is rendered and the body closure receives the full panel area.

pub fn subtitle(self, subtitle: impl Into<WidgetText>) -> Self

Show a muted subtitle line below the title. Has no effect when Drawer::title is unset.

pub fn close_on_backdrop(self, close: bool) -> Self

Whether clicking the dimmed backdrop dismisses the drawer. Default: true.

pub fn close_on_escape(self, close: bool) -> Self

Whether pressing Esc dismisses the drawer. Default: true.

pub fn show<R>( self, ctx: &Context, add_contents: impl FnOnce(&mut Ui) -> R, ) -> Option<R>

Render the drawer. Returns None while the drawer is fully closed (off-screen and not animating); otherwise Some(R) with the body closure’s return value.

The closure is invoked every frame the panel is on-screen, including while it slides in or out. Treat the body as ordinary layout — the slide animation is applied by translating the parent Area.

Trait Implementations

Formats the value using the given formatter.
