Rudimentary question: Adding MouseListener to JTable rows

I am adding a MouseListener to the rows of a table in order to add Drag and Drop to the rows (with Apple's D & D API).This is as far as I've gotten:

for (int i = 0; i < table.getRowCount(); i++) {
row[ i ].addMouseListener( rowListener );
}
Which returns the following error:
"...Undefined variable: row
row.addMouseListener( rowListener );
^ "

I [i] think [/i] that what I am looking for is to define "row" using something like:
" row = table.grabAllTheRows "
then add the MouseListener to each row:
"row[ i ].addMouseListener( rowListener )".

If I am on the wrong track, please let me know.

Swing does not provide with any functionality for trapping mouse motion in a JTable. You could however have a work around. You could add a component/panel in each of the cells and add a mouselistener to those components.

yep..you need to define the type of row first and then provide it an object reference..but you can eliminate the row variable by using table.getRow(i) method or it's equivalent in the API.

table.getRow(i).addMouseListener(rowListener);

Hi gsatsan;

Thanks for the comment. I tried it and this code:

for (int i = 0; i < table.getRowCount(); i++) {
table.getRow(i).addMouseListener(rowListener);
}

returns this error message:
"...Method getRow(int) not found in class javax.swing.JTable.
table.getRow(i).addMouseListener(rowListener);"
            ^
How do I fix it?

Thanks in advance.

You can implement your own getRow() like this :

suppose your table class is called MyTable :

public class MyTable extends JTable {
private MyTmodel
..........................
public Vector getRow(int row) {
 Vector v = new Vector();
 int cols = getColumnCount();
 for(int i = 0; i<cols; i++)
  v.addElement(getValueAt(row, i));
 return(v);
}

public Object[] getRow(int row) {
 int cols = getColumnCount();
 Object[] o = new Object[cols];
 for(int i = 0; i<cols; i++)
  o[i] = getValueAt(row, i);
 return(o);
}
..........................
}

, and so you have two methods which are returning a roe Vector or an row array elements of Objects.
 The same method you can use for "paste" a row, using setValueAt(int row, int col) method

Hi,

getRow() won't help. You need it to be Component to add mouse listener. JTable doesn't have components which correspond to rows. Add MouseListener directly to table and use columnAtPoint() and rowAtPoint() to get column/row information.
