Crate direct_gui

Draw GUI controls directly on a buffer

Usage

This crate is on crates.io and can be used by adding direct-gui to the dependencies in your project's Cargo.toml.

[dependencies]
direct-gui = "0.1"

and this to your crate root:

extern crate direct_gui;

Examples

use direct_gui::*;
use direct_gui::controls::*;

let screen_size = (800i32, 600i32);

// Create a buffer where we will render to
let mut buffer: Vec<u32> = vec![0; (screen_size.0 * screen_size.1) as usize];

// Create a new instance of the gui
let mut gui = Gui::new(screen_size);

// Load the sprite of a button
let button_img = gui.load_sprite_from_file("examples/button.png", Color::from_u32(0xFF00FF)).unwrap();

// Create a new button using the sprite loaded before at pixel (20, 10)
gui.register(Button::new_with_sprite(button_img).with_pos(20, 10));

// Handle "input events" by pretending that the mouse is hovering over the button.
let cs = ControlState {
    mouse_pos: (22, 12),
    ..ControlState::default()
};
gui.update(&cs);

// Finally render the current gui state to the buffer
gui.draw_to_buffer(&mut buffer);
