ComboBox / dropdown trigger sizing.

Fields

background_color: Option<Rgba>

ComboBox background color.

min_height: Option<f32>

Minimum trigger height in logical pixels.

min_width: Option<f32>

Minimum trigger width in logical pixels.

arrow_icon_size: Option<f32>

Dropdown arrow size in logical pixels.

arrow_area_width: Option<f32>

Width of the arrow clickable area, in logical pixels. None where the theme states no width (docs/platform-facts.md §2.24): GNOME’s dropdown draws its arrow inline, macOS’s width is only a measured range (~16–18px), and the iOS and Material platform presets and the community colour-scheme presets cite none.

disabled_opacity: Option<f32>

Opacity multiplier when disabled (0.0-1.0), applied to the whole widget on top of its disabled colours (see ThemeDefaults::disabled_opacity).

disabled_text_color: Option<Rgba>

ComboBox text color when disabled.

hover_background: Option<Rgba>

ComboBox background on hover.

disabled_background: Option<Rgba>

ComboBox background when disabled; None, the enabled background.

font: Option<FontSpec>

ComboBox font specification.

border: Option<WidgetBorderSpec>

ComboBox border specification.

Implementations

impl ComboBoxTheme

pub const FIELD_NAMES: &[&str]

All serialized field names for this widget theme, for TOML linting.

impl ComboBoxTheme

pub fn merge(&mut self, overlay: &Self)

Merge an overlay into this value. Some fields in the overlay replace the corresponding fields in self; None fields are left unchanged. Nested structs are merged recursively.

pub fn is_empty(&self) -> bool

Returns true if all fields are at their default (None/empty) state.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ComboBoxTheme

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ComboBoxTheme

where ComboBoxTheme: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>
