Struct MacPopover 

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

Authentic macOS AppKit NSPopover floating surface.

Features authentic balloon bubble geometry, arrow pointer directed at anchor points, dynamic scaling and opacity transitions, and theme-driven background/border colors.

Example

use egui_macview::{MacPopover, MacPopoverArrowEdge, MacTheme};

let theme = MacTheme::default();
let popover_rect = egui::Rect::from_min_size(egui::Pos2::new(50.0, 50.0), egui::vec2(160.0, 100.0));

MacPopover::new()
    .theme(&theme)
    .arrow_edge(MacPopoverArrowEdge::Top)
    .show(ui, popover_rect, |popover_ui| {
        popover_ui.label("Popover Content");
    });

Implementations

impl<'a> MacPopover<'a>

pub fn new() -> Self

Creates a new popover surface.

pub fn id(self, id_source: impl Hash + Debug) -> Self

Sets an explicit widget Id for this popover.

pub fn theme(self, theme: &'a MacTheme) -> Self

Injects dynamic theme to eliminate hardcoded metrics and colors.

pub fn arrow_edge(self, edge: MacPopoverArrowEdge) -> Self

Specifies the edge where the directional arrow emerges.

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

Sets custom offset along the arrow edge in points (defaults to center).

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

Scales the popover geometry around its center (used during zoom transitions).

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

Sets opacity alpha multiplier in [0.0, 1.0] for fade transitions.

pub fn show<R>( self, ui: &mut Ui, rect: Rect, add_contents: impl FnOnce(&mut Ui) -> R, ) -> (Response, R)

Renders the popover balloon and invokes add_contents for inner child widgets.
