Jtable seclections

[KP Kirchdörfer]

Hi;

I know this is a java question, but I'd like to ask here first before going to
a java forum, due to friendly and helpful approach.

I've managed to create and fill a Jtable with the help of a DefaultTableModel;
I've also managed to print the whole table (jtable.print() - that was too
easy :))  and I can make and undo selections (SingleIntervalSelections) with
the appropriate MouseListeners.

I googled and read a lot esp. the Java Tutorials, but I don't got a clue how
to deal with the selection.
I'd like to print or copy to clipboard the selected rows and columns, but I'm
stuck, how to get the "content" of the selection for further processing. I'm
under the impression, I'm just a small step away, I just don't get it :)

Any hints?

TIA
kp

It's been a while since I messed with JTables but it looks like you need
to get an array of selected row numbers and use that to access the
actual data in the table model - something like this might work where
myjtable is your JTable:

myselection = int[] myjtable.getSelectedRows

mymodel = DefaultTableModel myjtable.getModel

mydata = Vector mymodel.getDataVector

loop myindex =0 to myselection.length-1
 
    say mydata.elementAt(myselection[myindex])

    end

I don't know if that helps as I can't test it now but I wanted to at
least give you something to try.

Hi Kermit,
   thanks a lot for this explanation. It also will help me in my
implementation of PRINT using JTable's
when cross Tables are involved (PRINT A,B,C BY D VERSUS E)

Kind regards,
Thomas.

Thx Kermit, you've helped me shurely to get on the right track.
I missed the getDataVector method, and at least I was able to see the
selctions and also to see the problems :)
Selections seems to be a real mess, once a user change the sort order.

I started to work with the getValueAt(row, column) method, which is
independent from the users sort order  - but thats another story.

Thanks again
