Prevent scrolling when appending to JTextArea

Try:
yourJTextArea.select(1, 1);
It should work because it works well for my project.
Good luck! :-)

Capture Hyperlink click in JButton or JLabel

Simon,
I think you can add an ActionEvent by calling addxxxListener(...).

How to capture a Hyperlink click without JEditorPane

Simon
Maybe you can use two strings like:
String htmlText1 = "I love a ;
String htmlText2 = "person";
...
then make only the 2nd string link to the URL.
Good luck.

Centering the header of the columns in JTable

hi,
I use the HTML (i.e. "<HTML><center>Name</center></HTML>") to boldface and center the text of the header for all the columns in a JTable. But I can only boldface the text but could not center them. Does anybody know how to solve this problem? Thanks.

JTextField - Restrict length

hi,
To disable cut/copy/paste in a JtextField, you can create a JTextField and override the copy() and paste()
methods as below:
JTextField myTextField = new JTextField()
{
public void cut() {};
public void copy() {};
public void paste(){};
}
This is also disable cut().
Good luck.

Could we remove the Java cup icon from JFileChooser dialog?

Thanks, Paul.
My problem is same as that posted on JDC discussion forum: the JFileChooser extends a JDialog not a JFrame, so the Java cup icon still exists.
