A theming crate for fltk-rs, based on work by Remy Oukaour and Greg Ercolano, and schemes developed by the NTK GUI library.
Usage
[dependencies]
fltk = "1.1.6"
fltk-theme = "0.1"
Example
Setting the color theme:
use fltk::{prelude::*, *};
use fltk_theme::{ColorTheme, color_themes};
fn main() {
let a = app::App::default().with_scheme(app::Scheme::Gtk);
let theme = ColorTheme::from_colormap(color_themes::BLACK_THEME);
theme.apply();
let mut win = window::Window::default().with_size(400, 300);
let mut btn = button::Button::new(160, 200, 80, 40, "Hello");
btn.set_color(btn.color().lighter());
win.end();
win.show();
a.run().unwrap();
}
Setting the widget theme:
use fltk::{prelude::*, *};
use fltk_theme::{widget_themes, WidgetTheme, ThemeType};
fn main() {
let a = app::App::default();
let widget_theme = WidgetTheme::new(ThemeType::Aqua);
widget_theme.apply();
let mut win = window::Window::default().with_size(400, 300);
let mut btn = button::Button::new(160, 200, 80, 30, "Hello");
btn.set_frame(widget_themes::OS_DEFAULT_BUTTON_UP_BOX);
win.end();
win.show();
a.run().unwrap();
}
Setting the widget scheme:
use fltk::{prelude::*, *};
use fltk_theme::{WidgetScheme, SchemeType};
fn main() {
let a = app::App::default();
let widget_scheme = WidgetScheme::new(SchemeType::Clean);
widget_scheme.apply();
let mut win = window::Window::default().with_size(400, 300);
let mut btn = button::Button::new(160, 200, 80, 30, "Hello");
win.end();
win.show();
a.run().unwrap();

Widget Schemes
These provide schemes for widgets without color theming. Currently there are 4 schemes:
-
Clean: Taken from NTK's clear scheme.
-
Crystal: Taken from NTK's crystal scheme.
-
Gleam: Taken from NTK's gleam scheme.
-
SvgBased: This overrides FLTK's Base scheme round/rounded/oval FrameTypes which are drawn using scalable vector graphics.
