Swing vs AWT

Features

AWT(Abstract Windowing ToolKit)
Swing
  • A rich set of user interface components.

  • A robust event-handling model.

  • Graphics and imaging tools, including shape, color, and font classes.

  • Layout managers, for flexible window layouts that don't depend on a particular window size or screen resolution.

  • Data transfer classes, for cut-and-paste through the native platform clipboard.
  • All the features of AWT.

  • 100% Pure Java certified versions of the existing AWT component set (Button, Scrollbar, Label, etc.).

  • A rich set of higher-level components (such as tree view, list box, and tabbed panes).

  • Pure Java design, no reliance on peers.

  • Pluggable Look and Feel.

  • AWT (Pros & Cons)

    Pros
    Cons
  • Speed:- use of native peers speeds component performance.

  • Applet Portability:- most Web browsers support AWT classes so AWT applets can run without the Java plugin.

  • Look and Feel:- AWT components more closely reflect the look and feel of the OS they run on.
  • Portability:- use of native peers creates platform specific limitations.
    Some components may not function at all on some platforms.

  • Third Party Development:- the majority of component makers,including Borland and Sun, base new component development on Swing components.
    There is a much smaller set of AWT components available, thus placing the burden on the programmer to create his or her own AWT-based components.

  • Features:- AWT components do not support features like icons and tool-tips.

  • Swing (Pros & Cons)

    Pros
    Cons
  • Portability:- Pure Java design provides for fewer platform specific limitations.

  • Behavior:- Pure Java design allows for a greater range of behavior for Swing
    components since they are not limited by the native peers that AWT uses.

  • Features:- Swing supports a wider range of features like icons and pop-up tool-tips for components.

  • Vendor Support:- Swing development is more active.
    Sun puts much more energy into making Swing robust

  • Look and Feel:- The pluggable look and feel lets you design a single set of GUI components
    that can automatically have the look and feel of any OS platform (Microsoft Windows, Solaris, Macintosh, etc.). It also makes it easier to make global changes to your Java programs that provide greater accessibility (like picking a hi-contrast color scheme or changing all the fonts in all dialogs, etc.).
  • Applet Portability:- Most Web browsers do not include the Swing classes,so the Java plugin must be used.

  • Performance:- Swing components are generally slower and buggier than AWT,due to both the fact that they are pure Java and to video issues on various platforms. Since Swing components handle their own painting (rather than using native API's like DirectX on Windows) you may run into graphical glitches.

  • Look and Feel:- Even when Swing components are set to use the look and feel of the OS they are run on,
    they may not look like their native counterparts.
  • Swing Class Hierachy :
    JComponent class derived directly from Container, is the root class for most of UI component of Swing components.
