Struct Flex

Source

pub struct Flex { /* private fields */ }

Expand description

a Flexbox widget

§Example

use fltk::{prelude::*, *};
fn main() {
    let a = app::App::default();
    let mut win = window::Window::default().with_size(400, 300);
    let mut col = group::Flex::default().size_of_parent();
    col.set_type(group::FlexType::Column);
    let expanding = button::Button::default().with_label("Expanding");
    let mut normal = button::Button::default().with_label("Normal");
    col.fixed(&mut normal, 30);
    col.end();
    win.end();
    win.show();
    a.run().unwrap();
}

Implementations§

Source §

impl Flex

Source

pub fn new<'a, T: Into<Option<&'a str>>>( x: i32, y: i32, width: i32, height: i32, title: T, ) -> Flex

Creates a new widget, takes an x, y coordinates, as well as a width and height, plus a title

§Arguments

x - The x coordinate in the screen
y - The y coordinate in the screen
width - The width of the widget
heigth - The height of the widget
title - The title or label of the widget

To use dynamic strings use with_label(self, &str) or set_label(&mut self, &str). labels support special symbols preceded by an @ sign and for the associated formatting.

Source

pub fn default_fill() -> Self

Constructs a widget with the size of its parent
