Wraps NSView
and UIView
across platforms.
This implementation errs towards the UIView
side of things, and mostly acts as a wrapper to
bring NSView
to the modern era. It does this by flipping the coordinate system to be what
people expect in 2020, and layer-backing all views by default.
Views implement Autolayout, which enable you to specify how things should appear on the screen.
use cacao::color::Color;
use cacao::layout::{Layout, LayoutConstraint};
use cacao::view::View;
use cacao::appkit::window::{Window, WindowDelegate};
#[derive(Default)]
struct AppWindow {
content: View,
red: View,
window: Window
}
impl WindowDelegate for AppWindow {
const NAME: &'static str = "RootView";
fn did_load(&mut self, window: Window) {
window.set_minimum_content_size(300., 300.);
self.window = window;
self.red.set_background_color(Color::rgb(224, 82, 99));
self.content.add_subview(&self.red);
self.window.set_content_view(&self.content);
LayoutConstraint::activate(&[
self.red.top.constraint_equal_to(&self.content.top).offset(16.),
self.red.leading.constraint_equal_to(&self.content.leading).offset(16.),
self.red.trailing.constraint_equal_to(&self.content.trailing).offset(-16.),
self.red.bottom.constraint_equal_to(&self.content.bottom).offset(-16.),
]);
}
}

Structs
A clone-able handler to a ViewController
reference in the Objective C runtime. We use this
instead of a stock View
for easier recordkeeping, since it’ll need to hold the View
on that
side anyway.
Represents an action that can be displayed when a user swipes-to-reveal on a ListViewRow. You return this from the appropriate delegate method, and the system will handle displaying the necessary pieces for you.
Enums
Represents the “type” or “style” of row action. A Regular
action is
nothing special; do whatever you want. A Destructive
action will have
a special animation when being deleted, among any other system specialties.
This enum represents the different stock animations possible
for ListView row operations. You can pass it to insert_rows
and remove_rows
- reloads don’t get animations.
Specifies a row edge.
