Hey there!

I have been trying to get all my JTable cells to be not Editable so you can't change the info displayed on the JTable. It sounds easy to do but I cant seem to do it.

Any help would be appreciated
Thanks!!

Hi everyone,
It really depends on what your default editor component is
if your component is say a JTextArea the do the following


One more thing do not forget to add a table listener so that no matter which cell is clicked it cannot be edited or in your initialization you can do a loop an set all cells to uneditble mode

I you have any other questions on this subject post them here

Hi,
I guess you can implement the isEditable() method in your table model and return false and you table will not be editable. Let's see a quick example

public class MyTableModel extends AbstractTableModel{

public void isEditable(){
return false;
}
}

Then you have a table and you set its model to a MyTableModel object eg.

JTable table = new JTable();
table.setModel(new MyTableModel());

Remember to implement MyTableModel well so that it will have some data. I hope this helps

AbstractTableModel.isCellEditable(int,int) returns false by default, so you don't need to override it to get that behavior.

The DefaultTableModel implementation of that method returns true by default, so that one must be overriden if you wish to make cells un-editable.
