JxBrowser 6.0

This page will guide you through the major new features and improvements included into JxBrowser 6.0.

GPU-accelerated rendering

Apart from the standard lightweight (off-screen) rendering mode, now JxBrowser supports heavyweight (windowed, GPU-accelerated) rendering mode. The description of the difference between these two modes is given below.

In lightweight rendering mode Chromium engine renders web page off-screen using CPU. An image of the web page is saved in shared memory. JxBrowser reads the image from the shared memory and displays it using standard Java Graphics 2D API. This approach works great if you need a true lightweight Swing/JavaFX component for display of modern HTML5/JavaScript/CSS web pages.

To create a Browser instance with lightweight rendering mode use the following code:

Browser browser = new Browser(BrowserType.LIGHTWEIGHT);

In the heavyweight rendering mode, which is made default mode in JxBrowser 6, we embed a native window into Java frame and configure Chromium engine to render content into this native window using GPU. GPU-accelerated rendering in this case works much faster compared to lightweight rendering mode. In this mode the rendering performance is the same as in Google Chrome, allowing display of full screen video with 60fps.

To create Browser instance with heavyweight rendering mode use the following code:

Browser browser = new Browser();
Browser browser = new Browser(BrowserType.HEAVYWEIGHT);

JavaScript-Java Bridge

Performance

Transferring data between Java and JavaScript now works ~10 times faster.

JSArray & JSDictionary

In JxBrowser 6 JavaScript-Java Bridge API allows transferring arrays and dictionaries from JavaScript to Java code and vice versa. The following sample demonstrates how to work with JSArray:

browser.registerFunction("MyFunction", new BrowserFunction() {
    public JSValue invoke(JSValue... args) {
        // Returns ['Str', 123, true] array
        List array = new ArrayList();
        array.add("Str");
        array.add(123);
        array.add(true);
        return JSValue.create(array);
    }
});

Proxy API

Proxy API has been improved in JxBrowser 6. It now supports HTTP, HTTPS, FTP, and SOCKS protocols. The following sample demonstrates how to work with updated Proxy API:

String proxyRules = "http=foo:80;https=foo:80;ftp=foo:80;socks=foo:80";
String exceptions = "<local>";  // bypass proxy server for local web pages
contextParams.setProxyConfig(new CustomProxyConfig(proxyRules, exceptions));

BrowserContextParams contextParams = new BrowserContextParams("chromium-data-dir");
Browser browser = new Browser(new BrowserContext(contextParams));

CJK Input

With the heavyweight mode enabled on Mac OS X and Windows, JxBrowser component now allows CJK input, analogous to Google Chrome. Such input is enabled by default.
