Module unsegen::widget

Widget abstraction and some basic Widgets useful for creating basic building blocks of text user interfaces.

Example:

use unsegen::base::*;
use unsegen::widget::*;
use unsegen::widget::builtin::*;
use std::io::stdout;

struct MyWidget {
    layout: VerticalLayout,
    prompt: PromptLine,
    buffer: LogViewer,
}

impl Widget for MyWidget {
   fn space_demand(&self) -> Demand2D {
       let widgets: Vec<&Widget> = vec![&self.prompt, &self.buffer];
       self.layout.space_demand(widgets.as_slice())
   }
   fn draw(&self, window: Window, hints: RenderingHints) {
       let widgets: Vec<(&Widget, RenderingHints)> =
           vec![(&self.prompt, hints), (&self.buffer, hints.active(false))];
       self.layout.draw(window, widgets.as_slice());
   }
}


fn main() {
    let stdout = stdout();
    let mut term = Terminal::new(stdout.lock()).unwrap();
    let mut widget = MyWidget {
        layout: VerticalLayout::new(
            SeparatingStyle::AlternatingStyle(StyleModifier::new().invert(true))
        ),
        prompt: PromptLine::with_prompt(" > ".to_owned()),
        buffer: LogViewer::new(),
    };

    loop {
        // Put application logic here: read input, chain behavior, react to other stuff
        {
            let win = term.create_root_window();
            widget.draw(win, RenderingHints::new().active(true));
        }
        term.present();
    }
}
