Java GUI listeners without AWT
I am a starting Java developer, learning just from internet tutorials. I am learning full screen GUI applications. I was told yesterday that I shouldn't use AWT in my programs, because it is outdated. I already know about light and heavyweight components, the main problem is the mouse and keyboard listeners. Why is AWT outdated? How to make a program without AWT (adding listeners to JComponents etc) (what kind of Swing things can replace the AWT)?
Solution 1:
You're mis-interpreting the information given to you. You should avoid using Swing components with AWT components. It's OK to use Swing with the AWT listener structure, layout managers, etc. and in fact it's impossible not to.
Solution 2:
There have been some good answers, but I would like to cover a slightly different aspect. Things that Swing provides beyond AWT.
Components
Swing supports styled documents in JEditorPane
& JTextPane
& to a limited extent using HTML in some other JComponents
. AWT does not support styled documents in any component.
AWT provides no tree based structure like JTree
, no tabular structure such as JTable
, no version of JToolBar
.
AWT has no equivalent (that I can find or recall) for JColorChooser
& none for the simple utility class - JOptionPane
.
Listeners
As mentioned in a comment, see the 20+ extra/alternate listeners in the javax.swing.event
package.
Pluggable Look & Feel
Swing components can be set to a particular look & feel at run-time, including a native PLAF.
See the screen shots on the Nested Layout Example for some more samples.
Layouts
In addition to the plethora of AWT layouts, Swing provides:
BoxLayout
GroupLayout
OverlayLayout
ScrollPaneLayout
SpringLayout
ViewportLayout
Other
- Key Bindings. See How to Use Key Bindings for details.
-
UndoManager
for undo/redo ability in editable documents. - Inbuilt double buffering to avoid flicker on repaint.
-
SwingWorker
for responsive GUIs.
There is probably a lot more I missed in that brief description, but the bottom line is that Swing is an altogether newer and more enabled GUI toolkit.
Swing both builds on, and relies heavily on, classes in the AWT.
