Update jTable Filled from DB

Hi,

i'm having a question i'm making a small program that involves reading
from a DB and putting the data in jTable.

But when you select a row in the jTable and press a button there comes
an dialog that you can edit the data afterwards when you close the
dialog the jTable should be updated.

I can't seem to figure out how to make it update after closing the dialog

Thx in advance

I've not looked at your source code, but basically what you could do is
this:

- create a class that extends the DefaultTableModel, have it contain an
array of results to be displayed
- each time something changes, you
alter that array and revalidate the JTable

This way, the JTable will interact with the TableModel and will update
what is being shown.

Please consider working through Sun's GUI tutorial.

Hi,

Have a look at the following article I've put online yesterday:
http://jcsnippets.atspace.com/java/gui-graphics/creating-a-custom-
tablemodel-for-a-jtable.html

As for revalidation, call the method "revalidate()". You can find more
information on this in the Java Docs:
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JComponent.html#reval
idate()

Also, setting a new model for the JTable will have the same effect.

Best regards,

JayCee

When posting long URL's, they can be protected
from line wrapping by enclosing in '<', '>'. E.G.
<http://jcsnippets.atspace.com/java/gui-graphics/creating-a-custom-tablemodel-for
-a-jtable.html>

Thank you for the tip, Andrew - I did not know that. Very handy!

Best regards,

Actually,
<URL:http://jcsnippets.atspace.com/java/gui-graphics/creating-a-custom-tablemodel-for
-a-jtable.html>
is often safer. It was once the official standard for quoting URLs in
plain text, but was dropped in a later RFC simply because few people
were using it; however, it is still supported by some software,
including some software that will break up a URL that has merely been
enclosed in <...>.
