Makepad 2.0 Theme System
Overview
The Makepad 2.0 theme system provides a comprehensive set of design tokens accessed
through theme.* variables in Splash scripts. It delivers consistent styling for
colors, typography, spacing, and widget states across your entire application.
Three built-in themes are available:
mod.themes.dark -- dark desktop theme (default)mod.themes.light -- light desktop thememod.themes.skeleton -- minimal skeleton theme with hardcoded values
Golden rule: Always use theme.* variables instead of hardcoded values for any
color, font size, or spacing in production UIs. This ensures your app automatically
supports theme switching and maintains visual consistency.
Theme Setup in App::run
The theme must be loaded before widgets are loaded. The standard pattern is:
impl App {
fn run(vm: &mut ScriptVm) -> Self {
crate::makepad_widgets::theme_mod(vm);
script_eval!(vm, {
mod.theme = mod.themes.light
});
crate::makepad_widgets::widgets_mod(vm);
App::from_script_mod(vm, self::script_mod)
}
}
If you skip steps 1-2, the default theme is dark (set inside theme_mod).
The counter example uses the simplified one-liner crate::makepad_widgets::script_mod(vm)
which bundles steps 1-3 with the default dark theme.
How It Works Internally
theme_mod() does the following:
- Calls
makepad_draw::script_mod(vm) to load drawing primitives
- Creates the
mod.themes module
- Loads
theme_desktop_dark, theme_desktop_light, and theme_desktop_skeleton
- Sets
mod.theme = mod.themes.dark as the default
Then widgets_mod() creates mod.prelude.widgets_internal with theme: mod.theme,
making theme.* available in all widget scripts that use mod.prelude.widgets.*.
