Crate suzy 

Create an application with Suzy

Suzy allows you to create a GUI comprised of widgets.

The most basic app template will look something like this:

#[derive(Default)]
struct Data { }

impl WidgetContent for Data {
    fn init(_init: impl WidgetInit<Self>) {}
    fn children(&mut self, _receiver: impl WidgetChildReceiver) {}
    fn graphics(&mut self, _receiver: impl WidgetGraphicReceiver) {}
}

fn main() {
    Data::run_as_app();
}

Watch System

Suzy’s watch system provides the main way to define functionality within the framework. It enables you to describe the relationships between widgets in a declarative way.

For example, if you wanted to make a widget half the width of its parent:

init.watch(|this, rect| {
    this.child.set_width(rect.width() / 2.0);
});

When the parent changes size, the closure will be re-run and update the size of the child.

See the watch module documentation for more information about the watch system.
