Struct Printer

pub struct Printer { /* private fields */ }

Available on crate feature dep_fltk only.

Defines a printer object. Example usage:

use fltk::{prelude::*, *};
let mut but = button::Button::default();
but.set_callback(|widget| {
    let mut printer = printer::Printer::default();
    if printer.begin_job(1).is_ok() {
        printer.begin_page().ok();
        let (width, height) = printer.printable_rect();
        draw::set_draw_color(enums::Color::Black);
        draw::set_line_style(draw::LineStyle::Solid, 2);
        draw::draw_rect(0, 0, width, height);
        draw::set_font(enums::Font::Courier, 12);
        printer.set_origin(width / 2, height / 2);
        printer.print_widget(widget, -widget.width() / 2, -widget.height() / 2);
        printer.end_page().ok();
        printer.end_job();
    }
});
