Setting Up
First we're going to get a window setup so RAUI can render to it.
Creating the Project
Let's create a new Rust project and add our dependencies.
Create a new cargo project:
cargo new --bin my_project
Then add the following dependencies to the Cargo.toml:
[dependencies]
# The RAUI mother-crate
raui = { version = "*", features = ["app"] }
Initializing The Window
Next we need to setup our UI window. Using the raui-app crate this is super easy!
In most cases you will probably want to integrate RAUI with a game engine or other renderer, and in that case you would not use raui-app, you would use an integration crate like raui-tesselation-renderer. For now, though, we want to get right into RAUI without having to worry about integrations.
Go ahead and add the following to your main.rs file:
use raui::prelude::*;
fn main() {
DeclarativeApp::simple("RAUI Guide", WidgetNode::default());
}
We don't add any widgets yet, we'll get to that in the next step. At this point you should be able to cargo run and have a blank window pop up!
OK, not that cool. We're not here for a blank window, so let's go put some GUI on the screen!
