My objective here is to obtain a console-like-behaving component in Java, not necessarily in JTextArea, but this seemed like a logical thing to try first.

When I put the mouse over the Darker gray JTextArea the scroll pane does not get the event. In general my question is how can I make sure the parent of a component receives the event if the component didn't handle that ...
I'm implementing a GUI application in Jython, using Eclipse and PyDev plugin. The problem is that I have a hard time using the builtin debugger. When I start a debug session it just stops. Of course this should be expected as the program just creates a JFrame and then it's finished. So any breakpoints I put for different events .e.g. ...

What's the programmatic equivalent of clicking the close (x) button in the upper right corner of a JFrame? There's the dispose() method but that's not the same thing, since a JFrame can be set to do several different things upon closing (not to mention if there's a WindowListener involved) ...
For a hw assignment, I need to setup a JTable in Swing, and populate the table's contents via a custom model class that extends the AbstractTableModel.

Any suggestions? import javax.swing.*; import java.awt.*; import java.awt.event.*; public class JMous...

I can still navigate it using keyboard. ...
