Trait kas::draw::ThemeApi

pub trait ThemeApi {
    fn set_font_size(&mut self, pt_size: f32) -> TkAction;
    fn set_scheme(&mut self, scheme: &str) -> TkAction;
    fn list_schemes(&self) -> Vec<&str, Global>;

    fn set_theme(&mut self, _theme: &str) -> TkAction { ... }
}

Interface through which a theme can be adjusted at run-time

All methods return a TkAction to enable correct action when a theme is updated via Manager::adjust_theme. When adjusting a theme before the UI is started, this return value can be safely ignored.

Required methods

fn set_font_size(&mut self, pt_size: f32) -> TkAction

Set font size

Units: Points per Em (standard unit of font size)

fn set_scheme(&mut self, scheme: &str) -> TkAction

Change the colour scheme

If no scheme by this name is found the scheme is left unchanged.

fn list_schemes(&self) -> Vec<&str, Global>

List available colour schemes

Provided methods

fn set_theme(&mut self, _theme: &str) -> TkAction

Switch the theme

Most themes do not react to this method; kas_theme::MultiTheme uses it to switch themes.
