Lightweight rendering mode works great if you need a true lightweight Swing/JavaFX component that allows displaying modern HTML5/JavaScript/CSS web pages in your Java application. You can make this lightweight component semitransparent, display other components on top of it, put it into JLayeredPane or JInternalFrame, get notifications about mouse and keyboard events, etc. Heavyweight (GPU-accelerated) rendering mode works much faster compared to lightweight rendering mode. Rendering performance is the same as in Google Chrome. You can display full screen video or HTML5 animation with 60fps. Compared to lightweight rendering mode, CPU and memory usage is much smaller, because web page's content is rendered via GPU. read less

A heavyweight component relies on native code for its visual representation so it is drawn by the underlying operating system. Heavyweight components are those defined in the java.awt package A lightweight component does not rely on native code - it is implemented entirely in Java. This means that a lightweight componet is entirely portable. One consequence of the difference between heavyweight and lightweight components is that mixing them in the same application can cause trouble because they are drawn in different ways. You should avoid mixing them. read less

All Swing components are so-called "lightwight" components because they are written in java. If for example you run Swing application and try to analyze it using UI analyzing tool (e.g. WinSpy in windows) you see only one element: the window (JFrame) itself. All other components are drawn from OS point...

All Swing components are so-called "lightwight" components because they are written in java. If for example you run Swing application and try to analyze it using UI analyzing tool (e.g. WinSpy in windows) you see only one element: the window (JFrame) itself. All other components are drawn from OS point of view. Heavyweight API - AWT uses portable elements provided by OS. Since java must be portable among various operating system AWT is very limited. It implements only the minimal subset of screen elements supported by all platforms. However the AWT elements are mapped directly to the appropriate platform elements, so UI discovery tool will see them. These elements are named "heavy weight". read less

Light weight components are faster in response and performance. read less
