#4366 — Valid entry JTable

  To: comp.lang.java.gui
Hi

 Is it possible to get valid entries say for example a list of valid
entries description in each cell of like the first two rows when the
user keeps adding rows and the mouse selection is on an empty cell
line after I click the Okaty button?


Something like this -Valid entries

   Cell value at rowno1,colno1 is ......
   cell value at rowno1 colno2 is...

   and so on....

Any references,sample code,links might help me

Thanks

Sriram

Huh? Could you rephrase that?

maybe additionally to rephrasing a more sophisticated example would be nice.

That is a very long and confusing sentence. I'd find it easier to 
understand if you split it into several short sentences. Please also use 
  terms that others are more likely to understand. What is a "valid 
entry"? Are you talking of the validation of the values in a field using 
something like an InputVerifier? Or do you just want to print to stdout 
the text values of some JTextFields? Or of some JTable cells?

Did you just want to put some System.out.println statements in an 
ActionListener associated with your "Okay" JButton?

Ate it? Ah, as in "the dog ate my homework."

Well, your code compiles and runs!

It sounds like you want to be able to add rows of data to a tabular data 
structure and get the data back later: a TableModel, if you will. Even 
if you don't use JTable to view your data, a TableModel is a way to 
encapsulate your data. You access your data externally though the 
get/setValueAt methods, and you can hide the actual implementation: an 
array or collection or whatever. In the past, I have used an extension 
of AbstractTableModel to generate random test data for a prototype.

Here's some examples:
