I have a table like above. Initially all the cells except button column are not editable. I have created the table using custom TableModel
. My isCellEditable
in custom TableModel
looks like this:
public boolean isCellEditable(int rowIndex, int columnIndex) {
//System.out.println("isCellEditable: " + rowIndex + " " + columnIndex);
if(getColumnClass(columnIndex) == JButton.class)
return true;
else
return false;
}
But when I click on the Edit button of each row a JDialog
will pop up with that row (by constructing a JTable
in this dialog with only one row.) I can update the cell values in this JDialog's table. and then update them in the respective cells of that row.
I successfully updated the main table's row after updating here, only if my isCellEditable
return true. But this should not happen. Only when I click then I should be able to change isCellEditable
of the row as Editable and update and then make it uneditable.
I have seen the following post but was unable to implement it.
XxxTableModel
stores String.class
for JButton
as Renderer
/ Editor
for JTable
and for your code (is based on) too

both returns the same GUI, with the same ...
