Struct Popper 

pub struct Popper { /* private fields */ }

Implementations

impl Popper

pub fn new(open: Signal<bool>) -> Self

pub fn child<V: View + 'static>(self, child: V) -> Self

pub fn anchor(self, anchor: Anchor) -> Self

pub fn anchor_rect(self, rect: Rect) -> Self

pub fn anchor_view(self, id: ElementId) -> Self

pub fn anchor_self(self) -> Self

Anchors the overlay to the popper’s own layout box.

The popper is usually a zero-sized box in its parent, so this anchors the overlay near wherever the Popper happens to sit in the tree, not to the control the user clicked. For a menu or tooltip under a button, store the button’s ElementId (for example ctx.element() from its paint pass) and use Self::anchor_view instead; that stays correct when the button moves or the layout changes.

pub fn at_cursor(self) -> Self

pub fn anchor_point(self, x: f32, y: f32) -> Self

Anchors the overlay to a fixed screen-space point.

Unlike Self::at_cursor, the point does not follow later pointer movement. Use this for a context menu that should stay where the user clicked. The default placement is crate::overlay::Placement::Cursor, so the overlay’s top-left sits at the point.

pub fn anchor_static(self, point: Point) -> Self

Anchors the overlay to a fixed screen-space Point.

pub fn placement(self, placement: Placement) -> Self

pub fn offset(self, dx: f32, dy: f32) -> Self

pub fn overflow(self, overflow: OverlayOverflow) -> Self

pub fn layer(self, layer: OverlayLayer) -> Self

pub fn input_mode(self, mode: InputMode) -> Self

pub fn dismiss(self, dismiss: Dismiss) -> Self

pub fn on_dismiss(self, f: impl Fn() + 'static) -> Self

pub fn is_open(&self) -> bool

pub fn open(&self)

pub fn close(&self)

pub fn toggle(&self)

Trait Implementations

impl View for Popper

fn body(&self) -> impl View + 'static

fn hit_testable(&self) -> bool

fn layout_style_ctx(&self, _rt: &Runtime, _el: ElementId) -> LayoutStyle

fn accessibility(&self) -> Option<Accessible>

fn arrange_override( &self, _rt: &Runtime, _el: ElementId, _rect: Rect, _ctx: &mut LayoutCtx<'_>, ) -> bool

fn clip_self(&self) -> bool

fn clip_radius(&self) -> f32

fn paint_opacity(&self) -> Option<f32>

fn cache_layer(&self) -> bool

Allows the runtime to replay this element’s painted subtree from cache while its element revision and absolute paint context stay unchanged.

fn paint_opacity_ctx(&self, _rt: &Runtime, _el: ElementId) -> Option<f32>

fn paint_offset(&self) -> Vec2

fn paint_offset_ctx(&self, _rt: &Runtime, _el: ElementId) -> Vec2

fn paint_scale(&self) -> f32

fn paint_scale_ctx(&self, _rt: &Runtime, _el: ElementId) -> f32

fn paint_rotation(&self) -> f32

fn paint_rotation_ctx(&self, _rt: &Runtime, _el: ElementId) -> f32

fn foreground_filter(&self) -> Option<Filter>

fn captures_pointer_ctx(&self, _rt: &Runtime, _el: ElementId) -> bool

fn reuse_state(&self, _old: &Self)

fn test_id(&self) -> Option<String>

fn focus_trap(&self) -> bool

fn accepts_tab(&self) -> bool

fn accepts_text_input(&self) -> bool

Whether this view edits text when focused.

fn ime_caret_rect(&self) -> Option<Rect>

Caret rectangle in window coordinates, used to place the platform IME candidate window. Widgets with a text caret return the box the caret occupies; hosts fall back to the focused element’s bounds when this is None.

fn paint_foreground(&self, _ctx: &mut PaintCtx<'_>)

fn accepts_drop(&self, _payload: &DragPayload) -> bool

fn on_drag_over(&self, _pos: DropPosition, _ctx: &mut EventCtx<'_>)

fn on_drop(&self, _pos: DropPosition, _ctx: &mut EventCtx<'_>)

fn on_drag_start(&self, _ctx: &mut EventCtx<'_>)

fn on_drag_end(&self, _end: DragEnd, _ctx: &mut EventCtx<'_>)
