§Flemish

An elmish architecture for fltk-rs, inspired by Iced.

§Usage

Add flemish to your dependencies:

[dependencies]
flemish = "0.5"

A usage example:

use flemish::{
    button::Button, color_themes, frame::Frame, group::Flex, prelude::*, OnEvent, Sandbox, Settings,
};

pub fn main() {
    Counter::new().run(Settings {
        size: (300, 100),
        resizable: true,
        color_map: Some(color_themes::BLACK_THEME),
        ..Default::default()
    })
}

#[derive(Default)]
struct Counter {
    value: i32,
}

#[derive(Debug, Clone, Copy)]
enum Message {
    IncrementPressed,
    DecrementPressed,
}

impl Sandbox for Counter {
    type Message = Message;

    fn new() -> Self {
        Self::default()
    }

    fn title(&self) -> String {
        String::from("Counter - fltk-rs")
    }

    fn update(&mut self, message: Message) {
        match message {
            Message::IncrementPressed => {
                self.value += 1;
            }
            Message::DecrementPressed => {
                self.value -= 1;
            }
        }
    }

    fn view(&mut self) {
        let col = Flex::default_fill().column();
        Button::default()
            .with_label("Increment")
            .on_event(|_| Message::IncrementPressed);
        Frame::default().with_label(&self.value.to_string());
        Button::default()
            .with_label("Decrement")
            .on_event(|_| Message::DecrementPressed);
        col.end();
    }
}

Modules§

Macros§

  • cmap
  • widget_extends
    Defines a set of convenience functions for constructing and anchoring custom widgets. Usage: fltk::widget_extends!(CustomWidget, BaseWidget, member); It basically implements Deref and DerefMut on the custom widget, and adds the aforementioned methods. This means you can call widget methods directly, for e.x. custom_widget.set_color(enums::Color::Red). For your custom widget to be treated as a widget it would need dereferencing: group.add(&*custom_widget);

Structs§

  • ColorMap
    Color map struct. (index, r, g, b)
  • ColorTheme
    A theme is just a Vec of colormaps
  • Settings
  • WidgetScheme
    A widget scheme sets the style of drawing a widget without interfering with coloring
  • WidgetTheme
    A widget theme is a scheme + a set of default colors
