    pub material_theme: Option<MaterialThemeFile>,
    pub selected_colors: HashMap<String, Color32>,
}

Fields

theme_mode: ThemeMode

contrast_level: ContrastLevel

material_theme: Option<MaterialThemeFile>

selected_colors: HashMap<String, Color32>

Implementations

impl MaterialThemeContext

pub fn setup_fonts(font_name: Option<&str>)

pub fn setup_local_fonts(font_path: Option<&str>)

pub fn setup_local_theme(theme_path: Option<&str>)

Internal implementation for preparing local themes from JSON files

This function handles the loading and parsing of Material Design theme JSON files. It supports both runtime file loading and build-time constant inclusion.

Arguments

• theme_path - Optional path to theme JSON file. If None, uses build-time constants.

Implementation Details

• First attempts to load from specified file path (if provided)
• Falls back to build-time included theme constants
• Finally falls back to default built-in theme
• Parses JSON and stores in static PREPARED_THEMES collection
• Replaces any existing theme with the same name

pub fn load_themes()

Internal implementation for loading prepared themes to the global theme context

This function applies the first prepared theme from the PREPARED_THEMES collection as the active global theme. It creates a new MaterialThemeContext with the theme data and updates the global theme state.

Behavior

• Takes the first theme from prepared themes collection
• Creates a MaterialThemeContext with default settings (Light mode, Normal contrast)
• Updates the global GLOBAL_THEME with the new context
• If no themes were prepared, the global theme remains unchanged

pub fn load_fonts(ctx: &Context)

Load all prepared fonts to the egui context
