# direct-gui
Simple direct rendering GUI controls
### [Documentation](https://docs.rs/direct-gui/)
## Usage
Add this to your `Cargo.toml`:
```toml
[dependencies]
direct-gui = "0.1"
```
And this to your crate root:
```rust
extern crate direct_gui;
```
### Run the examples
On Linux you need the `xkb` & `wayland` packages as required by `minifb` -- `sudo apt install libwayland-cursor0 libxkbcommon-dev libwayland-dev`
cargo run --example button
cargo run --example label
cargo run --example sprite
## Examples
```rust
use direct_gui::*;
use direct_gui::controls::*;
let screen_size = (800i32, 600i32);
// Create a buffer where we will render to
let mut buffer: Vec = 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", 0xFF00FF).unwrap();
// Create a new button using the sprite loaded before at pixel (20, 10)
gui.register(Button::new(button_img).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);
```
