Expander / disclosure row geometry.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

header_height: f32

Collapsed header row height in logical pixels.

arrow_icon_size: f32

Disclosure arrow size in logical pixels.

hover_background: Option<Rgba>

Expander header background on hover.

arrow_color: Option<Rgba>

Disclosure arrow/chevron color.

arrow_side: Option<ArrowSide>

Which end of the header row the disclosure arrow sits at: before the title, or at the row’s end. None where the theme states none (docs/platform-facts.md §2.27).

arrow_gap: Option<f32>

Space between the arrow’s icon box (arrow_icon_size square) and the title after it, or, for a trailing arrow, the header content before it, in logical pixels. None where the platform states none: AppKit documents no disclosure geometry (docs/platform-facts.md §2.27).

content_indent: Option<f32>

Horizontal distance from the expander’s leading inner edge (inside its frame, where it has one) to the content it reveals, in logical pixels. None where the platform states none: AppKit documents no disclosure geometry (docs/platform-facts.md §2.27).

frame_enabled: Option<bool>

Whether the expander draws a frame (its border) around its header and the content it reveals: KDE’s has none, libadwaita’s and WinUI’s are framed. None where the theme states none (docs/platform-facts.md §2.27).

font: ResolvedFontSpec

Expander font specification.

border: ResolvedWidgetBorder

Expander border specification.
