pub struct Printer { /* private fields */ }Available on non-Android only.
Expand description
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();
}
