Tutorial Callback Property Binds

You can bind callbacks to changes in widget properties or custom properties. This is done differently from widget callbacks where you prepare a CallbackConfig first. Instead, you can use the "bind" method on the property you wish to bind to.

Here is an example of binding a callback to a labels height property, using a closure:

use ez_term::*;
let (root_widget, mut state_tree, mut scheduler) = load_ui();

let my_callback = |context: Context| {

    true
};

let state = state_tree.get("my_label").as_label_mut();
state.size.height.bind(Box::new(my_callback), &mut scheduler);

The same example but using a function:

use ez_term::*;
let (root_widget, mut state_tree, mut scheduler) = load_ui();

fn my_callback(context: Context) -> bool {

    true
};

let state = state_tree.get("my_label").as_label_mut();
state.size.height.bind(Box::new(my_callback), &mut scheduler);
