This crate aims to simplify generating gui from a data structure.
[dependencies]
fltk = "1.2.16"
fltk-form = "0.1"
fltk-form-derive = "0.1"
You can also git clone
the repo and run the example directly:
$ cargo run --example basic
#[macro_use]
extern crate fltk_form_derive;
use fltk::{prelude::*, *};
use fltk_form::{FltkForm, HasProps};
#[derive(Copy, Debug, Clone, FltkForm)]
pub enum MyEnum {
A,
B,
C,
}
#[derive(Debug, Clone, FltkForm)]
pub struct MyStruct {
a: f64,
b: f64,
c: String,
d: MyEnum,
e: bool,
}
impl MyStruct {
pub fn default() -> Self {
Self {
a: 0.0,
b: 3.0,
c: String::new(),
d: MyEnum::A,
e: true,
}
}
}
fn main() {
let my_struct = MyStruct::default(); // <-- instantiate your struct
let a = app::App::default().with_scheme(app::Scheme::Gtk);
app::set_background_color(222, 222, 222);
let mut win = window::Window::default().with_size(400, 300);
let mut grp = group::Group::default()
.with_size(300, 200)
.center_of_parent();
let form = my_struct.generate(); // <-- generate the form
grp.end();
let mut btn = button::Button::default()
.with_label("print")
.with_size(80, 30)
.below_of(&grp, 5)
.center_x(&grp);
grp.set_frame(enums::FrameType::EngravedFrame);
win.end();
win.show();
let v = form.get_prop("b"); // <-- get a single property
assert_eq!(v, Some("3.0".to_owned()));
btn.set_callback(move |_| {
println!("{:?}", form.get_props()); // <-- get a HashMap of the properties
});
a.run().unwrap();
}
You can also rename properties using the rename_prop() method:
#[macro_use]
extern crate fltk_form_derive;
use fltk::{prelude::*, *};
use fltk_form::{FltkForm, HasProps};
#[derive(Copy, Debug, Clone, FltkForm)]
pub enum MyEnum {
A,
B,
C,
}
#[allow(non_snake_case)]
#[derive(Debug, Clone, FltkForm)]
pub struct MyStruct {
very_long_name: f64,
second_value: f64,
full_name: String,
Choices: MyEnum,
do_it: bool,
}
impl MyStruct {
pub fn default() -> Self {
Self {
very_long_name: 0.0,
second_value: 3.0,
full_name: String::new(),
Choices: MyEnum::A,
do_it: true,
}
}
}
fn main() {
let my_struct = MyStruct::default();
let a = app::App::default().with_scheme(app::Scheme::Gtk);
app::set_background_color(222, 222, 222);
let mut win = window::Window::default().with_size(400, 300);
let mut grp = group::Group::default()
.with_size(300, 200)
.center_of_parent()
.with_label("Form 1")
.with_align(enums::Align::Top | enums::Align::Left);
let mut form = my_struct.generate();
form.set_label("");
form.rename_prop("very_long_name", "First Value");
form.rename_prop("second_value", "Second Value");
form.rename_prop("full_name", "Full name");
form.rename_prop("do_it", "Do it?");
grp.end();
grp.set_frame(enums::FrameType::EngravedFrame);
let mut btn = button::Button::default()
.with_label("print")
.with_size(80, 30)
.below_of(&grp, 5)
.center_x(&grp);
win.end();
win.show();
let v = form.get_prop("First Value");
assert_eq!(v, Some("0.0".to_owned()));
btn.set_callback(move |_| {
println!("{:?}", form.get_props());
});
a.run().unwrap();
}
