valueChange in a ListSelection when i

[ben chato]

Hi !
I've got a problem with my JTable.
Normally, when we click on a row, its background becomes blue (it is now selected !)
But, when the cellEditor is a JComboBox, even if i change the value in the 3rd row, table.getSelectedRow() still returns 0. (and the first row is still blue).
How can i get the row index of the JComboBox i clicked and force the selectedRow ?
thanks !

Add a listener to the JComboBox. When its value changes, update your table to select the row in which the JComboBox resides. The problem is trying to determine the row number that the JComboBox is in, because that's the row that you have to select after the JComboBox's value changes.

If you're adding the JComboBox's dynamically, meaning that your application will add a variable amount of JComboBox's to your JTable, then just subclass JComboBox and add a new attribute that stores the row number in which the combox box is located in your JTable. Add a method to your new class that will allow the JTable to get the row number from the combo box, then you will know the row to select.

Thanks, it could be a good idea but i think it won't work.
My JComboBox are not placed dynamically : i use them as a DefaultCellEditor for my Column.

I finally found the answer :
1- I placed a mouseListener on the JTable
2- When i click on a cell, the mousePressed tell me the point.
3- I get the rowAtPoint()
4- I send the focus on the row with :
try {
table.editCellAt(line,0);
table.getEditorComponent().requestFocus();
lsm = table.getSelectionModel();
lsm.setSelectionInterval(line,line);
} catch (Exception ex) {
...
}
that's all !
