What is @lumino/widgets?

@lumino/widgets is a library for building complex, high-performance web applications with a focus on modularity and flexibility. It provides a set of widgets and layout management tools that can be used to create sophisticated user interfaces.

What are @lumino/widgets's main functionalities?

Creating a Simple Widget

This code demonstrates how to create a simple widget using @lumino/widgets. The widget displays 'Hello, Lumino!' and attaches itself to the document body.

const { Widget } = require('@lumino/widgets');

class MyWidget extends Widget {
  constructor() {
    super();
    this.node.textContent = 'Hello, Lumino!';
  }
}

const widget = new MyWidget();
widget.attach(document.body);

Layout Management

This code demonstrates how to use the BoxLayout to manage the layout of multiple widgets. Two widgets are created and added to a BoxLayout, which is then set as the layout for a main widget that is attached to the document body.

const { Widget, BoxLayout } = require('@lumino/widgets');

const layout = new BoxLayout({ direction: 'left-to-right' });
const widget1 = new Widget();
widget1.node.textContent = 'Widget 1';
const widget2 = new Widget();
widget2.node.textContent = 'Widget 2';

layout.addWidget(widget1);
layout.addWidget(widget2);

const mainWidget = new Widget();
mainWidget.layout = layout;
mainWidget.attach(document.body);

DockPanel for Complex Layouts

This code demonstrates how to use the DockPanel for more complex layouts. Two widgets are created and added to a DockPanel, with the second widget being docked to the right of the first widget. The DockPanel is then attached to the document body.

const { Widget, DockPanel } = require('@lumino/widgets');

const dock = new DockPanel();
const widget1 = new Widget();
widget1.node.textContent = 'Docked Widget 1';
const widget2 = new Widget();
widget2.node.textContent = 'Docked Widget 2';

dock.addWidget(widget1);
dock.addWidget(widget2, { mode: 'split-right', ref: widget1 });

dock.attach(document.body);
