Explain the difference between AWT and SWT?
Answer:
Abstract Windows Toolkit (AWT) is the original Java GUI tool kit.
AWT's comes standard with every version of Java technology.
It is very stable.
It doesn’t need to be installed.
AWT is a very simple tool kit with limited GUI components, layout managers, and events.
Lowest-common denominator (LCD) approach is used for for AWT.
Some commonly used components like Tables, Trees, Progress Bars, and others, are not supported.
Applications that need more component types need to be created from scratch.
SWT is based on a peer implementation.
It has an adequate set of controls to make most applications on a host-by-host basis, creating emulated controls for any not supplied by the particular host. Thus, it overcomes the LCD problem faced by AWT.
In SWT, the peers are just wrappers on host controls.
In AWT, peers can provide services to minimize the differences between hosts.
SWT is a good enough portable solution but not as well as Swing.
