WebEngine is a software component that allows developers to embed web content within applications. It acts as a mini-browser, enabling the display of HTML, CSS, and JavaScript, which helps create rich user interfaces. This technology is commonly used in applications that require web-based features, such as displaying online content or integrating web services. Many popular frameworks and platforms, like Qt and Electron, utilize WebEngine to enhance their applications. By leveraging this technology, developers can create cross-platform applications that maintain a consistent look and feel, while also providing access to the vast resources available on the web.
