Struct MacSplitView 

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

Authentic macOS AppKit split container (NSSplitView equivalent).

Features draggable hairline dividers, min/max pane constraints, collapse states, optional drag handle indicators, and horizontal or vertical divider orientations.

Example

use egui_macview::{MacSplitOrientation, MacSplitView, MacTheme};

let theme = MacTheme::default();

MacSplitView::new("main_split", MacSplitOrientation::Horizontal)
    .theme(&theme)
    .min_first(100.0)
    .show(ui,
        |left_ui| { left_ui.label("Sidebar"); },
        |right_ui| { right_ui.label("Detail Content"); },
    );

Implementations

impl<'a> MacSplitView<'a>

pub fn new( id_source: impl Hash + Debug, orientation: MacSplitOrientation, ) -> Self

Creates a split view with state tracked automatically via egui::Id.

pub fn with_pos( id_source: impl Hash + Debug, orientation: MacSplitOrientation, pos: &'a mut f32, ) -> Self

Creates a split view binding directly to an external &mut f32 position variable.

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

Injects dynamic theme to eliminate hardcoded metrics and colors.

pub fn min_first(self, min: f32) -> Self

Minimum size constraint for the first pane in points.

pub fn max_first(self, max: f32) -> Self

Maximum size constraint for the first pane in points.

pub fn min_second(self, min: f32) -> Self

Minimum size constraint for the second pane in points.

pub fn collapsed_first(self, collapsed: bool) -> Self

Collapses the first pane completely (width/height = 0).

pub fn collapsed_second(self, collapsed: bool) -> Self

Collapses the second pane completely (width/height = 0).

pub fn show_handle(self, show: bool) -> Self

Controls visibility of the subtle center drag handle pill on the divider.

pub fn default_ratio(self, ratio: f32) -> Self

Default split fraction if not yet persisted.

pub fn split_panes(&mut self, ui: &mut Ui) -> (Rect, Rect)

Computes the layout geometry, handles divider drag interaction and painting, and returns (first_rect, second_rect) for caller-managed child rendering.

pub fn show<R1, R2>( self, ui: &mut Ui, first: impl FnOnce(&mut Ui) -> R1, second: impl FnOnce(&mut Ui) -> R2, ) -> (R1, R2)

Renders the split container and both pane closures, returning their outputs.
