States

States are pretty simple, it is how you take any data in and out of your widgets!

Creating a state

An Example of a state is

#[derive(State)]
pub struct IntState(i32);

This will allow you to then insert the state into your app, and retrieve it from any function!

Registering a state

If you need an example of how to insert a state, all you have to do is:

App::new()?.states(IntState(0));

This will register your state, allowing you to use it in any widget!

Using a state

Say you need to get/modify the int in IntState

It's pretty simple! Just make a widget that takes in that state!

fn widget(int_state: ResMut<IntState>) -> WidgetResult {
   int_state.0 += 1;
   Ok(())
}

See! Now you can modify any state within your widgets!
